Your task sounds very straight-forward. You need to write a Python application that reads your table, and writes data formatted as XML to a file. In Python, that is easy to do. I have included a simple example at the end of this email. This example reads a table in a PostgreSQL database using psycopg - Python-PostgreSQL Database Adapter (http://initd.org/Software/). If you do not already have the database adapter you need for your database, you can learn about others at: http://www.python.org/sigs/db-sig/. > > I might not have all the data fields supported in the > DTD in my database. Is it okay if I leave some fields > as blank. > Maybe. You might (1) include the tags with no data or (2) include the tags with default values that you want to initialize or (3) omit the tags altogether. This depends on your needs and on the needs of the application that will consume the XML file you produce. Hope the helps.

One would need to convert these into the appropriate entity references (< and &) first. The escape() method in xml.sax.saxutils is pretty useful for this purpose.

Uh, not much to go on here. When you say latest versions, do you mean PyXML 0.8.3 and 4Suite 1.0a3? Did you have any other versions of PyXML or 4Suite installed previously? If so, which ones, and do you have the old scripts in your binary path, still? Any odd environment variables? How did you install 4Suite? python setup.py install? Or did you install an RPM or Windows binaries? Is this on Windows or Unix? How did you go about running the test suite? What error did you get? From dkuhlman at cutter.rexx.com Fri Nov 5 22:49:52 2004 From: dkuhlman at cutter.rexx.com (Dave Kuhlman) Date: Fri Nov 5 22:49:46 2004 Subject: [XML-SIG] ANN: New version of generateDS.py Message-ID: <20041105134952.A6170@cutter.rexx.com> Version 1.7a of generateDS.py is available. This new work was done with the help and guidance of Lloyd Kvam. The significant new features are: - Support for mixed content -- When an element is defined with mixed="true", generateDS.py generates a class with a very different data model, basically a list of container objects for nested text and elements. It's clumsey and it has limitations, but at least you are not completely stuck when your XML Schema defines elements with mixed content. - Extensions - When element A is defined as an extension whose base is element B, then generateDS.py generates class A as a subclass of class B. Thanks especially to Lloyd for his guidance in using subclasses to solve this one. Without his guidance and design suggestions, I would have wandered cluelessly into something quite kludgy. - Ability to access the text content of elements defined to have attributes but no nested elements. Formerly, generateDS.py did not support this. Now, for these classes, there is a valueOf_ member, which is used to access text content. The lack of support for mixed content was discussed by Uche in his article "XML Data Bindings in Python", which is at: http://www.xml.com/pub/a/2003/06/11/py-xml.html What is generateDS.py? -- generateDS.py generates Python data structures (for example, class definitions) from an XML Schema document. These data structures represent the elements in an XML document described by the XML Schema. It also generates parsers that load an XML document into those data structures, as well as export methods that write classes out to XML and to Python literal data structures. In addition, a separate file containing subclasses (stubs) is optionally generated. The user can add methods to the subclasses in order to process the contents of an XML document. You can find generateDS.py here: http://www.rexx.com/~dkuhlman/generateDS.html http://www.rexx.com/~dkuhlman/generateDS-1.7a.tar.gz And, as usually, your suggestions and comments are welcome.

Well, since it sounds as if you'd like to solve your XML processing task using Python, this probably is the right place. The only problem I can see with your question is that there is not really enough detail for anyone to help. Sounds as if you want to export data from a database (what sort? SQL? Object? Hash table? You say "tables" so I'd guess SQL). Which DBMS? Does it have XML export capabilities you can just use without writing your own code? Does the DTD *require* (not just allow) fields for which the source database has no value? If so, are there business rules you can apply to set defaults? etc. etc. I could ask a hundred questions, but it's much better if you just get specific and tell us what tools you're using, your precise goals, etc. Snippets of code or data samples will probably get you the best responses. -- Uche Ogbuji Fourthought, Inc. http://uche.ogbuji.net http://4Suite.org http://fourthought.com A hands-on introduction to ISO Schematron - http://www-106.ibm.com/developerworks/edu/x-dw-xschematron-i.html Schematron abstract patterns - http://www.ibm.com/developerworks/xml/library/x-stron.html Wrestling HTML (using Python) - http://www.xml.com/pub/a/2004/09/08/pyxml.html XML's growing pains - http://www.adtmag.com/article.asp?id=10196 XMLOpen and more XML Hacks - http://www.ibm.com/developerworks/xml/library/x-think27.html A survey of XML standards - http://www-106.ibm.com/developerworks/xml/library/x-stand4/ From subha.fernando at gmail.com Mon Nov 8 05:47:22 2004 From: subha.fernando at gmail.com (Subha Fernando) Date: Mon Nov 8 05:47:59 2004 Subject: [XML-SIG] newbie queries on xml processing Message-ID: <31f4e3904110720476e442a5e@mail.gmail.com> Hi, I'm new to this group as well as to Python & XML.

One of my objectives was to ensure that even if a process was interrupted (though not catastrophically) that the my close method could successfully close all tags and I end up with a wellformed XML file. No given that XmLWriter keeps track of state I thought I could just have a stack of try blocks that could close each tag rather than me tracking state as well, i.e. try: self._logger.endElement( u'items') except RuntimeError,e: pass try: self._logger.endElement( u'page') except RuntimeError,e: pass try: self._logger.endElement( u'pages') except RuntimeError,e: pass try: self._logger.endElement( u'template') except RuntimeError,e: pass As there didn't seem to be any point in my keeping track of something that was already managed. However __poptag def __poptag(self, tag): state = self.__stack.pop() self._flowing, self.__lang, expected_tag, \ self._packing, self._dtdflowing = state if tag != expected_tag: raise RuntimeError, \ "expected , got " % (expected_tag, tag) self._prefix = self._prefix[:-self.indentation] which manages the state doesn't restore the stack state after a RuntimeError is raised. So it is destructive even on error. For what I am doing a simple fix that I used was to restore the stack in the event of a RuntimeError as in def __poptag(self, tag): state = self.__stack.pop() self._flowing, self.__lang, expected_tag, \ self._packing, self._dtdflowing = state if tag != expected_tag: self.__stack.append(state) # restore state raise RuntimeError, \ "expected , got " % (expected_tag, tag) self._prefix = self._prefix[:-self.indentation] It would seem to me, that not restoring the stack is probably wrong when a runtime error has been raised. You may not want to bail out completely when this occurs and take corrective action, but then you have try and pick apart the error string to work out what went wrong. you have no way of winding back and recovering and outputting the correct tag because you have none of the other details that are stored in the stack with the tag (state). At least in my case this approach/fix works very well, but there may be other cases that I haven't thought about where this approach breaks down. What are other peoples thoughts on this ? Is the existing behaviour mandated as part of the standard API ?

In the current (Nov 11 2004) CVS checkout, this happens in xml.sax.drivers.drv_pyexpat.SAX_expat.close(): e.g parseFile() calls self.parser.Parse("", 1) and then calls self.close(); the following self.parser.Parse("", 0) throws an ExpatException. close() should probably check the current state and do the "catch errors" Parse call only if parsing has not stopped. Checking current state can be done using XML_GetParsingStatus(), which is apparently not available through pyexpat, unfortunately. The problem is easily reproducible by running the PyXML testsuite; test_marshal and test_saxdrivers fail, the tail of the traceback being e.g. File "/home/mitr/PyXML-0.8.4/test/test_saxdrivers.py", line 64, in test_sax1 parser.parseFile(open(findfile("test.xml"))) File "/usr/lib/python2.4/site-packages/_xmlplus/sax/drivers/drv_pyexpat.py", line 74, in parseFile self.close() File "/usr/lib/python2.4/site-packages/_xmlplus/sax/drivers/drv_pyexpat.py", line 132, in close if self.parser.Parse("", 0) != 1: ExpatError: parsing finished: line 116, column 0 ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=106473&aid=1064741&group_id=6473 From encoder-iso-8859-3 at mozilla.org Sat Nov 13 16:47:10 2004 From: encoder-iso-8859-3 at mozilla.org (encoder-iso-8859-3@mozilla.org) Date: Sat Nov 13 16:47:33 2004 Subject: [XML-SIG] Delivery reports about your e-mail Message-ID: <20041113154731.921D71E4002@bag.python.org> Your message was not delivered due to the following reason(s): Your message could not be delivered because the destination server was unreachable within the allowed queue period.

No doubt they are silly; but I've looked for the answer in books, in the docs, in clp, and here, and had no luck. 1) What is the canonical way to escape the quotes inside of an attribute? I have a cgi script, and may be getting things from users that I want to stuff inside of the attributes. That is, I have code like this: favoriteFood=fs.getfirst('favoriteFood') # fs is a cgi.FieldStorage structure attrDct={'favoriteFood':favoriteFood} and I'm afraid I'll get "Mama's" for an answer, giving me XML like (likewise, "Ben & Jerry's" gives me worries) I've cast about for what I thought were likely names, but didn't find any . 2) Similarly, in XHTML, in an href, is there some obvious function that I somehow overlooked to quote the ampersands? Possibly both have the same answer?

Nope, that's all there is. Within an attribute you only have to replace whatever your quoting character is (single or double quote) and ampersand. For example: s.replace('&', '&').replace('"', '"') then you can the attribute value as print 'myattr="%s"' % s or wahtever's appropriate. /r$ -- Rich Salz Chief Security Architect DataPower Technology http://www.datapower.com XS40 XML Security Gateway http://www.datapower.com/products/xs40.html XML Security Overview http://www.datapower.com/xmldev/xmlsecurity.html From mike at skew.org Sun Nov 14 22:45:02 2004 From: mike at skew.org (Mike Brown) Date: Sun Nov 14 22:45:05 2004 Subject: [XML-SIG] escaping ' or " in attributes In-Reply-To: <190.32f3b50b.2ec7f19e@aol.com> "from Hefferon9@aol.com at Nov 13, 2004 06:24:14 pm" Message-ID: <200411142145.iAELj2Aw005952@chilled.skew.org> Hefferon9@aol.com wrote: > 1) What is the canonical way to escape the quotes inside of an attribute?

Depends on how you're creating the X(HT)ML. If you're just doing prints then of course you will need to do your own replacements. I suggest you read Uche Ogbuji's article on xml.com entitled "Proper XML Output In Python" (Google for it) One thing you should note is that XML has an "apos" entity, but HTML does not. Therefore if you are intending to generate HTML 4.0 browser compatible XHTML (as it appears you are), then you need to use "'" instead of "'" when putting an apostrophe/single-quote in an attribute value that is delimited by those same characters.

Thank you! The limitation of the Photon Hypothesis According to the electromagnetic theory of light, its energy is related to the amplitude of the electric field of the electromagnetic wave, W=eE^2(where E is the amplitude). It apparently has nothing to do with the light's circular frequency v. To explain the photoelectric effect, Einstein put forward the photon hypothesis. His paper hypothesized light was made of quantum packets of energy called photons. Each photon carried a specific energy related to its circular frequency v, E=hv. This has nothing to do with the amplitude of the electromagnetic wave. For the electromagnetic wave that the amplitude E has nothing to do with the light's frequency v, if the light's frequency v is high enough, the energy of the photon in light is greater than the light's energy, hv>eE^2. Apparently, this is incompatible with the electromagnetic theory of light. THE UNCERTAINTY PRINCIPLE IS UNTENABLE By re-analysing Heisenberg's Gamma-Ray Microscope experiment and one of the thought experiment from which the uncertainty principle is demonstrated, it is actually found that the uncertainty principle cannot be demonstrated by them. It is therefore found to be untenable. Key words: uncertainty principle; Heisenberg's Gamma-Ray Microscope Experiment; thought experiment The History Of The Uncertainty Principle If one wants to be clear about what is meant by "position of an object," for example of an electron., then one has to specify definite experiments by which the "position of an electron" can be measured; otherwise this term has no meaning at all. --Heisenberg, in uncertainty paper, 1927 Are the uncertainty relations that Heisenberg discovered in 1927 just the result of the equations used, or are they really built into every measurement? Heisenberg turned to a thought experiment, since he believed that all concepts in science require a definition based on actual, or possible, experimental observations. Heisenberg pictured a microscope that obtains very high resolution by using high-energy gamma rays for illumination. No such microscope exists at present, but it could be constructed in principle. Heisenberg imagined using this microscope to see an electron and to measure its position. He found that the electron's position and momentum did indeed obey the uncertainty relation he had derived mathematically. Bohr pointed out some flaws in the experiment, but once these were corrected the demonstration was fully convincing. Thought Experiment 1 The corrected version of the thought experiment Heisenberg's Gamma-Ray Microscope Experiment A free electron sits directly beneath the center of the microscope's lens (please see AIP page http://www.aip.org/history/heisenberg/p08b.htm or diagram below) . The circular lens forms a cone of angle 2A from the electron. The electron is then illuminated from the left by gamma rays--high-energy light which has the shortest wavelength. These yield the highest resolution, for according to a principle of wave optics, the microscope can resolve (that is, "see" or distinguish) objects to a size of dx, which is related to and to the wavelength L of the gamma ray, by the expression: dx = L/(2sinA) (1) However, in quantum mechanics, where a light wave can act like a particle, a gamma ray striking an electron gives it a kick. At the moment the light is diffracted by the electron into the microscope lens, the electron is thrust to the right. To be observed by the microscope, the gamma ray must be scattered into any angle within the cone of angle 2A. In quantum mechanics, the gamma ray carries momentum as if it were a particle. The total momentum p is related to the wavelength by the formula, p = h / L, where h is Planck's constant. (2) In the extreme case of diffraction of the gamma ray to the right edge of the lens, the total momentum would be the sum of the electron's momentum P'x in the x direction and the gamma ray's momentum in the x direction: P' x + (h sinA) / L', where L' is the wavelength of the deflected gamma ray. In the other extreme, the observed gamma ray recoils backward, just hitting the left edge of the lens. In this case, the total momentum in the X direction is: P''x - (h sinA) / L''. The final x momentum in each case must equal the initial X momentum, since momentum is conserved. Therefore, the final X moment are equal to each other: P'x + (h sinA) / L' = P''x - (h sinA) / L'' (3) If A is small, then the wavelengths are approximately the same, L' ~ L" ~ L. So we have P''x - P'x = dPx ~ 2h sinA / L (4) Since dx = L/(2 sinA), we obtain a reciprocal relationship between the minimum uncertainty in the measured position, dx, of the electron along the X axis and the uncertainty in its momentum, dPx, in the x direction: dPx ~ h / dx or dPx dx ~ h. (5) For more than minimum uncertainty, the "greater than" sign may added. Except for the factor of 4pi and an equal sign, this is Heisenberg's uncertainty relation for the simultaneous measurement of the position and momentum of an object. Re-analysis The original analysis of Heisenberg's Gamma-Ray Microscope Experiment overlooked that the microscope cannot see the object whose size is smaller than its resolving limit, dx, thereby overlooking that the electron which relates to dx and dPx respectively is not the same. According to the truth that the microscope can not see the object whose size is smaller than its resolving limit, dx, we can obtain that what we can see is the electron where the size is larger than or equal to the resolving limit dx and has a certain position, dx = 0. The microscope can resolve (that is, "see" or distinguish) objects to a size of dx, which is related to and to the wavelength L of the gamma ray, by the expression: dx = L/(2sinA) (1) This is the resolving limit of the microscope and it is the uncertain quantity of the object's position. The microscope cannot see the object whose size is smaller than its resolving limit, dx. Therefore, to be seen by the microscope, the size of the electron must be larger than or equal to the resolving limit. But if the size of the electron is larger than or equal to the resolving limit dx, the electron will not be in the range dx. Therefore, dx cannot be deemed to be the uncertain quantity of the electron's position which can be seen by the microscope, but deemed to be the uncertain quantity of the electron's position which can not be seen by the microscope. To repeat, dx is uncertainty in the electron's position which cannot be seen by the microscope. To be seen by the microscope, the gamma ray must be scattered into any angle within the cone of angle 2A, so we can measure the momentum of the electron. But if the size of the electron is smaller than the resolving limit dx, the electron cannot be seen by the microscope, we cannot measure the momentum of the electron. Only the size of the electron is larger than or equal to the resolving limit dx, the electron can be seen by the microscope, we can measure the momentum of the electron. According to Heisenberg's Gamma-Ray Microscope Experiment, the electron��s momentum is uncertain, the uncertainty in its momentum is dPx. dPx is the uncertainty in the electron's momentum which can be seen by microscope. What relates to dx is the electron where the size is smaller than the resolving limit. When the electron is in the range dx, it cannot be seen by the microscope, so its position is uncertain, and its momentum is not measurable, because to be seen by the microscope, the gamma ray must be scattered into any angle within the cone of angle 2A, so we can measure the momentum of the electron. If the electron cannot be seen by the microscope, we cannot measure the momentum of the electron. What relates to dPx is the electron where the size is larger than or equal to the resolving limit dx .The electron is not in the range dx, so it can be seen by the microscope and its position is certain, its momentum is measurable. Apparently, the electron which relates to dx and dPx respectively is not the same. What we can see is the electron where the size is larger than or equal to the resolving limit dx and has a certain position, dx = 0. Quantum mechanics does not rely on the size of the object, but on Heisenberg's Gamma-Ray Microscope experiment. The use of the microscope must relate to the size of the object. The size of the object which can be seen by the microscope must be larger than or equal to the resolving limit dx of the microscope, thus the uncertain quantity of the electron's position does not exist. The gamma ray which is diffracted by the electron can be scattered into any angle within the cone of angle 2A, where we can measure the momentum of the electron. What we can see is the electron which has a certain position, dx = 0, so that in no other position can we measure the momentum of the electron. In Quantum mechanics, the momentum of the electron can be measured accurately when we measure the momentum of the electron only, therefore, we have gained dPx = 0. And, dPx dx =0. (6) Thought Experiment 2 Single Slit Diffraction Experiment Suppose a particle moves in the Y direction originally and then passes a slit with width dx(Please see diagram below) . The uncertain quantity of the particle's position in the X direction is dx, and interference occurs at the back slit . According to Wave Optics , the angle where No.1 min of interference pattern can be calculated by following formula: sinA=L/2dx (1) and L=h/p where h is Planck's constant. (2) So the uncertainty principle can be obtained dPx dx ~ h (5) Re-analysis The original analysis of Single Slit Diffraction Experiment overlooked the corpuscular property of the particle and the Energy-Momentum conservation laws and mistook the uncertain quantity of the particle's position in the X direction is the slit's width dx. According to Newton first law , if an external force in the X direction does not affect the particle, it will move in a uniform straight line, ( Motion State or Static State) , and the motion in the Y direction is unchanged .Therefore , we can learn its position in the slit from its starting point. The particle can have a certain position in the slit and the uncertain quantity of the position is dx =0. According to Newton first law , if the external force at the X direction does not affect particle, and the original motion in the Y direction is not changed , the momentum of the particle in the X direction will be Px=0 and the uncertain quantity of the momentum will be dPx =0. This gives: dPx dx =0. (6) No experiment negates NEWTON FIRST LAW. Whether in quantum mechanics or classical mechanics, it applies to the microcosmic world and is of the form of the Energy-Momentum conservation laws. If an external force does not affect the particle and it does not remain static or in uniform motion, it has disobeyed the Energy-Momentum conservation laws. Under the above thought experiment , it is considered that the width of the slit is the uncertain quantity of the particle's position. But there is certainly no reason for us to consider that the particle in the above experiment has an uncertain position, and no reason for us to consider that the slit's width is the uncertain quantity of the particle. Therefore, the uncertainty principle, dPx dx ~ h (5) which is demonstrated by the above experiment is unreasonable. Conclusion Every physical principle is based on the Experiments, not based on MATHEMATICS, including heisenberg uncertainty principle. Einstein said, One Experiment is enough to negate a physical principle. >From the above re-analysis , it is realized that the thought experiment demonstration for the uncertainty principle is untenable. Therefore, the uncertainty principle is untenable. Reference: 1. Max Jammer. (1974) The philosophy of quantum mechanics (John wiley & sons , Inc New York ) Page 65 2. Ibid, Page 67 3. http://www.aip.org/history/heisenberg/p08b.htm Single Particles Do Not Exhibit Wave-Like Behavior Through a qualitative analysis of the experiment, it is shown that the presumed wave-like behavior of a single particle contradicts the energy-momentum conservation laws and may be expained solely through particle interactions. DUAL SLIT INTERFERENCE EXPERIMENT PART I If a single particle has wave-like behavior, it will create an interference image when it has passed through a single slit. But the experimental result shows that this is not the case Only a large number of particles can create an interference image when they pass through the two slits. PART II In the dual slit interference experiment, the single particle is thought to pass through both slits and interfere with itself at the same time due to its wave-like behavior. The motion of the wave is the same direction as the particle. If the particle passes through a single slit only, it can not be assumed that it has wave-like behavior. If it passes through two slits, it, and also the acompanying wave must be assumed to have motion in two directions. But a wave only has one direction of motion. PART III If one slit is obstructed in the dual slit interference experiment and a particle is launched in this direction, then according to Newton��s first law, (assuming no external forces,) it will travel in a uniform straight line. It will not pass through the closed slit and will not make contact with the screen. If it has wavelike behavior, there is a probability that it will make contact. But this will negate Newton��s first law and the law of conservation of energy and momentum. Both quantum mechanics and classical mechanics are dependent on this law. THE EXPLANATION FOR THE WAVE-LIKE BEHAVIOR OF THE PARTICLE In the dual slit interference experiment, if one slit is unobstructed, particles will impact at certain positions on the screen. But when two slit are open, the particles can not reach these positions. This phenomenon brings us to the greatest puzzle regarding the image of the particle. But when we consider that the particle may experience two or more reflections, the puzzle may be resolved. As indicated, when one of the slits is obstructed, the particles that move towards this slit can not get to the screen. However, they can return to the particle source by reflection and then pass through the open slit and reach the above positions since they have different paths when one or two slits are open. This indicates that wave-like behavior may be explained solely on the basis of particle interactions. EXPERIMENTAL TEST The above may be tested by an experiment which can absorb all the particles that move towards the closed slit. If one slit is obstructed by the stuff which can absorb all the particles that move towards it, the intensity of some positions on the screen should decrease. THE CONCLUSION Single particles do not exhibit wave-like behavior. The similarity of wave and particle behavior may be attributed to initial impulse and path. The quantum mechanical explanation is suspect, since the probability of one particle and one particle among a large quantity reaching the screen is equal in mathematics and physics.

Perhaps not before - but certainly shortly after. This much depends whether I can find the time to do that on Tuesday, or whether it has to wait until Friday.

There are two approaches. 1. Modify distutils so that it invokes Embedded VC (or whatever compiler you need to use); this would be useful for all distutils-based extensions. You would use this technique then through python setup.py build --compiler=evc4 (or some other name you come up with) 2. Manually invoke the compiler. Run setup.py build with MSVC6, and check what compiler invocations are performed, with what command line options. Then perform the same invocations manually, replacing cl.exe appropriately.

Message-ID: <200411291934.44488.frans.englich@telia.com> Hello, I need some guidance for the various XML implementations. In my project I use the Python DOM classes for instantiations of my XML data, and I need XPath functionality, WXS validation, and XSLT processing. Currently, I pipe out my structures to libxml2/libxslt's xmllint/xsltproc for doing validation, and XSLT processing. libxml2 is capable, but the solution is ugly, and slow(de-serialization/serialization). In addition, I lack XPath functionality. I have no intentions to skip Python's XML structures, and use for example libxml2's. So, my plan is to get XPath somewhere, and perhaps be able to substitute libxml2 for something more Pythonic while I'm at it. From what I can tell, there is three major packages to keep an eye on: 1) standard Python; 2) PyXML; 3) 4suite. Let me see if I got this straight: * Python have _no_ XPath implementation (right?) * PyXML install an XPath implementation(written by fourthought) into Python's package xml(xml.xpath). Is it version 1.0? Is it robust and stable? * PyXML has xml.xslt; not an option since it's not stable/production quality, according to the docs -- or what is its status? How much "experimental" is it? * 4suite has XPath(another implementation written by fourthought..?) and robust xslt. * Neither PyXML nor 4suite has a W3C XML Schema stack, so I'll have to look elsewhere; one alternative is XSV but it brings in addition a dependency on PyLTXML. Looks like continuing to pipe to libxml2's xmllint(or link) is still the best alternative. What is the best option(s) for me? With my interest of keeping the dependencies down, should I go for PyXML-XPath + PyXML-XSLT _if_ it's good enough or libxslt + libxml2-WXS? I could use 4suite's XSLT, but since I nevertheless will have a dependency on libxml2/libxslt for WXS I can use that(and eat the speed penalty). Important is it has a future(maintained..) and is stable/trustable. What should I go for, and what have I missed? BTW, is there any plans to merge any XSLT/XPath stack into vanilla Python? (when?) It's functionality often needed, AFAICT. Yes, I'm new on the Python & XML front..

Although it was written to meet my own simple needs, I suggest you take a look at libxml2dom: http://www.python.org/pypi?:action=display&name=libxml2dom It should be possible to feed DOM nodes from libxml2dom into PyXML's XPath implementation, although I suppose I ought to wrap the libxml2 XPath functionality itself in order to be able to drop that particular dependency on PyXML. I did hear something about 4Suite and XPath convenience methods on nodes, and that did make me wonder if some kind of standard might emerge that I could implement in libxml2dom. Anyway, I've been using libxml2dom with libxslt without unnecessary serialisation, so this may be what you're looking for. If you and others want to improve the software, I may establish a SourceForge project for it and let development follow that course.
