Everything works just fine so long as my XML file is not too long. After a certain length however, the character handler flags errors and the whole parsing process grinds to a halt. Is there some limit to the amount of character data I can parse from a file? If I change the order of the sections in my XML file, the error seems to occur at more or less the same place. If I substitute several copies of a section that was previously read OK into the top of my file, the same thing happens after about the same amount of data has been read.

Gak! There's a tiny but possibly relevant error in the example. ;-( Just calling the Parse() method with data causes the parser to expect more data; to tell it you're done, you need to call Parse() with the optional second argument set to true (an empty data string is fine): p.Parse('', 1) This tells the parser that there isn't any more input, so anything that hasn't been reported will be reported. (I'll fix the documentation.) Now, if you've passed the complete document already, this shouldn't be a real problem in practice. If this doesn't fix it for you, please provide specific code and a sample document that exhibit this problem, and the exact error you're seeing. That will make it much easier to help diagnose. -Fred -- Fred L.

In doing so it has focused attention on the modeling process, whether with languages inside or outside the UML family. The UML series of conferences is the premier venue for the exchange of innovative technical ideas and experiences relating to modeling. UML 2003 will include conference papers, workshops, tutorials and a tool exhibition. We invite three kinds of papers; although the lengths vary, each accepted paper will be allocated the same length slot in the conference programme. RESEARCH PAPERS describing innovative research on any aspect of modeling. SHORT EXPERIENCE PAPERS describing experience of significant application of modeling. Such papers will be judged by the quality of their contribution to industrial best-practice (rather than to the body of research knowledge). SHORT TOOL PAPERS describing innovative work on modeling-related tools. Such papers may concern tools with any licensing model (e.g. commercial or open source). They will be judged on their interest to the modeling community, and on the contribution they make to future tool-building within it. Topics include, but are not limited to: - lessons learned from modeling - tool support for any aspect of modeling or model use - models in the development and maintenance process - model evaluation, formal or informal - meta-modeling - model-driven engineering - semantics of modeling languages - domain-specific and concern-oriented modeling. Papers concerning modeling languages other than UML are welcome, but authors must bear in mind that their readers will, in general, be most familiar with UML. Hard Deadline for Abstracts 08 April 2003 Hard Deadline for Submissions 15 April 2003 Notification to Authors 24 June 2003 Final Version of Accepted Papers 29 July 2003 Paper Submissions: Submit your manuscript electronically in Postscript or PDF using the Springer LNCS style. Full papers should be 10-15 pages in length, short papers 2-4 pages. Full details, including more specific guidelines on the preparation of papers, can be found on the conference website. Papers will undergo a thorough process of review by a programme committee comprising leading experts from academia and industry; however, papers which are too long may be rejected without review. Proceedings will be published by Springer Verlag in the LNCS series. All papers must be original, unpublished, and not submitted simultaneously for publication elsewhere. Workshop and Tutorial Submissions: Proposals for advanced tutorials and workshops are requested: details of the proposal process are on the conference website. Important dates are listed below. Workshop deadline for submissions: 21 April 2003 Workshop notification of acceptance: 30 April 2003 Tutorial deadline for submissions: 29 June 2003 Tutorial notification of acceptance: 20 July 2003 Tutorial notes camera-ready copy deadline: 21 September 2003 See the conference website http://www.umlconference.org for details. %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% General Chair Grady Booch, USA Conference Chair Jon Whittle, USA Programme Chair Perdita Stevens, UK Workshop Chair Ana Moreira, Portugal Tutorial Chair Joao Araujo, Portugal Local Arrangements Sherif Yacoub, USA Publicity Chairs Geri Georg, USA and Jean-Michel Bruel, France %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%% From dev-xml@smartology.nl Thu Dec 5 16:49:42 2002 From: dev-xml@smartology.nl (Remy C.

The goal of this workshop is to look at issues related to the integration of non-functional properties expression, evaluation, and prediction in the context of component-based software engineering development. It is now widely recognized that what makes Component-Based Software Engineering (CBSE) hard to efficiently use is the fact that components are easy to produce but not easy to compose. This scope is addressed by a number of ongoing researches. In the context of this particular workshop we would like to focus on the difficulty of predicting the overall behavior and offered quality of service (in a broad sense, e.g. performance, dependability) of a composite out of its "internal" components. This implies that a software builder should have the behavior and the quality of service offered and required of each components expressed in some way, as well as some support tool or underlying framework supporting the composition of these added-value features. The aim of this workshop is to bring together practitioners and academics that are currently working around these topics to highlight the ongoing solutions and the problems encountered. The workshop is organized on two half-day sessions. The morning session is dedicated to invited talks and presentations. Followed, in the afternoon, by working sessions. The number and subject of these sessions will be decided by the organizers depending upon the position papers. A number of open questions will be addressed during the workshop. These questions will be refined, selected and modified according to the early discussions of the day, and some working sessions will be organized in order to give some indications on their answer. Examples of open questions: - How can we constraint/improve my component-based design with QoS annotations? - What research path should we take to make progress in predicting system behavior based on components behavior? - How do we decompose system behavior to get specific components requirements for non-functional system properties? Researchers and practitioners are invited to submit position papers on topics related to the workshop. A partial list of topics is: - Composition Language - Software performance modeling and evaluation - QoS specification - ADLs and their use in supporting features composition - Software dependability - Compositionality - Modeling methods and tools for non-functional requirements - Industrial case studies The 5-10 pages (single-spaced, 12-point, 1-inch margins) papers should be submitted either in postscript or a pdf format, via email to bruel@univ-pau.fr. The workshop organizers will review the submissions and select papers that present relevant and interesting ideas and concepts that can contribute to the discussions that will take place in the workshop. The workshop proceedings will be made available before the start of the workshop on the workshop website and may appear as a technical report at one of the organizers universities.

When feature_validation is set to false, endElement works and validation is still enabled.

When the above feature is set to 1 (true) the parser does not call the endElement(self) function. Example code: class myParser(ContentHandler): def __init__(self): pass def startElement(self, name): print 'start:', name def endElement(self, name): print 'end:', name With feature_validation set to false (o) or removing the line completely ... the result is: start: taga start: tagb end: tagb end: taga With feature_validation set to true (1) the result is: start: taga start: tagb > > An other problem (not related) is that the locator function: > > > > def setDocumentLocator(self, locator): > > self.locator = locator > > > > doesn't work > > Again, what do you mean by "doesn't work"? Example code: class myParser(ContentHandler): def __init__(self): pass def setDocumentLocator(self, locator): self.locator = locator def startElement(self, name): print 'start:', name print self.locator.getLineNumber() def endElement(self, name): print 'end:', name Running the above results in a self.locator does not have the property getLineNumber() error.

The right way to do that is to raise a SAXException in your ErrorHandler callback.

They append the warning/error to a list which can be read by the main program when the parser returns. How can I raise an SAXException so that the parser will return without halting the program ?

Raise the exception in your handler using a raise statement, then catch it using a try/except statement where you call the parser.

In that case, I can only wish you good luck, as you will need quite a lot of debugging to understand this. My initial thought is that you may be calling the wrong Expat copy, assuming multiple copies of Expat functions live inside Apache. This could be verified by setting breakpoints on the various Expat functions, to see which of them are invoked; adding printf statements inside PyXML's copy of Expat may also help. Of course, should not happen, as Python should use RTLD_LOCAL (BTW: what operating system?) If it is not that, you will have to perform step-by-step debugging, first on the Python level, e.g. by printing to a file in /tmp. If the ExpatBuilder loses its curNode attribute, print the contents of self.__dict__ in each callback function (i.e. *_handler); printing the keys might be sufficient. If that ever changes in an unreasonable way, then check whether the identity of the dict changes. If the dictionary loses the key, find the latest point where it is still there, and the earliest point where it is gone. This either points to the source of the problem, or you find that there are no Python statements in-between (i.e. in one callback, it was there until the end, and in the next callback, it is gone). Then you will have to use a C debugger. HTH, Martin From fdrake@acm.org Thu Dec 12 18:44:02 2002 From: fdrake@acm.org (Fred L.

For example transform = InputSource.DefaultFactory.fromString(XSLT, "ujds.xslt") This avoids errors if you try to do something later that performs resolution against a relative URI.

This exception does mask the real problem, unfortunately, but I'm about 90% sure that you're doing something (XSLT document() call, XInclude resolution, xsl:import or something) that tries to resolve a relative URI. The problem is that you haven't provided a base URI, so 4Suite rightly complains (though in an obfuscated way: I'll look into that). I pointed to the likely solution above. You may also want to browse my article on 4Suite: http://www.xml.com/pub/a/2002/10/16/py-xml.html Which gives a fuller example and some discussion.

Thanks, it works now! I have one more thing though - As I already have the XML file parsed to a DOM instance, it would be a nice thing if I could use that DOM instance instead of reading the whole XML file again from disk. I have tried this approach: def ProcessFile(dom, input, output): xsltprocessor = Processor() transform = InputSource.DefaultFactory.fromUri("ujds.xslt") xsltprocessor.appendStylesheet(transform) result = xsltprocessor.runNode(dom, input) if result: open(output, "w").write(result) Which results in a file with this line only: I am trying to output as HTML, which now works nicely through the other way. How can I (if possible/feasible at all) just use the DOM instance instead of loading the file? > I pointed to the likely solution above.

Okay, I have subscribed, but I think that this first problem I have run into is related to PyXML, not 4Suite. After having build an exe file and whatever other files py2exe has deemed necessary I run the exe file and get this output: Traceback (most recent call last): File "", line 26, in ?

I read http://uche.ogbuji.net:8080/uche.ogbuji.net/tech/akara/pyxml/domlettes/ where I can see that Domlette should be able to do the work that I am currently using minidom for. I can see that the return result of NonvalidatingReader.parseUri is a cDocument instance which does not offer the same methods as dom instances from minidom. This is not a big problem as long as there are something similar available, however I can't seem to find any documentation about what methods are available for cDocument objects, not even google could come up with anything useful, so could somebody direct me to the documentation I am seeking, if such does indeed exist? -- Anders -----BEGIN GEEK CODE BLOCK----- Version: 3.12 GCS/O d--@ s:+ a-- C++ $UL+++ P++ L+++ E- W+ N(+) o K? w O- M-- V PS+ PE@ Y+ PGP+ t 5 X R+ tv+ b+ DI+++ D+ G e- h !r y? ------END GEEK CODE BLOCK------ PGPKey: http://pgp.mit.edu:11371/pks/lookup?op=get&search=0x8BFECB41 From mike@skew.org Sun Dec 15 12:03:03 2002 From: mike@skew.org (Mike Brown) Date: Sun, 15 Dec 2002 05:03:03 -0700 (MST) Subject: [XML-SIG] py2exe and switching from PyXML 4Suite In-Reply-To: <20021215114049.GA21192@eddie.local> "from Anders Bruun Olsen at Dec 15, 2002 12:40:49 pm" Message-ID: <200212151203.gBFC34Jd034204@chilled.skew.org> Anders Bruun Olsen wrote: > I can't seem to find any documentation about what methods are available > for cDocument objects I don't think there is any yet.

We didn't add a getElementsByTagName *method* to cDomlette, as I warn in http://www.xml.com/pub/a/2002/12/11/py-xml.html "There is also at least one warning to attach to my suggestions to use Domlette. The book makes frequent use of the DOM method getElementsByTagName, which is not supported in Domlette, for simplicity. An equivalent function is very easy to write for yourself. I would suggest an implementation that uses Python generators and I will present just such an implementation in a forthcoming article."

Mine is 2.2+. Okay, I have now read up on iterators and generator - WOW! that's so cool!.. I immediately rewrote the search part of my program that had been giving me problems - with generators it just works perfectly and the code is so much simpler! I have implemented Uche's generators now and the function that loads an XML file into my programs internal format has now gone from 6-7 seconds load time to 1-2 second for the 219Kb XML file I am using for testing on my Athlon XP 1800+. Now - my program also saves it's data to disk by creating a dom and filling it with the right nodes and then writing it to disk with PrettyPrint (which takes over 20 seconds on my machine with the 219Kb file). I am sure this can be done much faster with 4Suite somehow, but how? right now I use xml.dom.implementation to create the empty dom, I am betting it is possible to do the same using domlette, I just can't grok how without a little helping hand :) Also it would be great if there was a way to ditch PrettyPrint as I would then be completely rid of PyXML, which seems to be giving py2exe some problems.

Rather than from xml.dom.ext import PrettyPrint use from Ft.Xml.Domlette import PrettyPrint Domlette's PrettyPrint is written in C (with Python fall-back), and is much faster. > right now I use xml.dom.implementation to create the empty dom, I am > betting it is possible to do the same using domlette, I just can't grok > how without a little helping hand :) Ouch. So you're using 4DOM, not Domlette, which is probably a bigger reason for slow performance than PrettyPrint Instead of xml.dom.implementation Use from Ft.Xml.Domlette import implementation Again I must warn you that Domlette approximates DOM and is not a full DOM. You already found the lack of getElementsByTagName. There are other subtle differences. That having been said, I have not run into a situation where Domlette is not a suitable DOM substitute. > Also it would be great if there was a way to ditch PrettyPrint as I > would then be completely rid of PyXML, which seems to be giving py2exe > some problems. Well, the above would remove dependency from PyXML. However, I think we would all like at least a report of the problems py2exe is having with PyXML, since it would be nice if that combo worked. > Once again, thanks for the help so far, you guys are great! :) I'm glad we've been of help.

I don't think there is a simple way to disable entity expansion from the internal subset, because I don't know of any XML parsers that offer this option. Maybe Xerces does? After all, DOM does keep entity ref stuff around and I think Xerces is the strictest DOM implementation out there, which means the undrlying parser probably reports all lexical entities, rather than just those that need resolution.

No. A pretty printer is expected to produce output that may have different white space usage from a plain printer. This is the whole point of a pretty printer. If you don't like that effect, then you should use a plain printer. Can't really have it both ways unless you design a pretty printer specific to your own format. I think you may be able to get closer to what you want with PrettyPrint(root, preserveElements=["raw"]) But I'm not sure that it gets you all the way. -- Uche Ogbuji Fourthought, Inc. http://uche.ogbuji.net http://4Suite.org http://fourthought.com A Python & XML Companion - http://www.xml.com/pub/a/2002/12/11/py-xml.html XML class warfare - http://www.adtmag.com/article.asp?id=6965 MusicBrainz metadata - http://www-106.ibm.com/developerworks/xml/library/x-thi nk14.html From anders@bruun-olsen.net Tue Dec 17 16:31:50 2002 From: anders@bruun-olsen.net (Anders Bruun Olsen) Date: Tue, 17 Dec 2002 17:31:50 +0100 Subject: [XML-SIG] PrettyPrint In-Reply-To: <200212171654.30453.scjuonline@web.de> References: <200212171654.30453.scjuonline@web.de> Message-ID: <20021217163149.GA1556@eddie.local> On Tue, Dec 17, 2002 at 04:54:30PM +0100, JS wrote: > I've got the following problem: > If I save the following xml file using PrettyPrint() > > bar > I get: > ##################PrettyPrint > > > > > > bar > > Now next time I read in the xml, a new text node is created in the DOM tree > due to the indent an newline behind the first element. > I could use Print since it doesn't add any additional data.

I haven't tried this myself, but it sounds like what you are looking for is a normalize function - that way you should be able to rid yourself of the extra whitespace and linebreaks.

If you mean that the printed document is not the same (for some definition of "same") as the original document. However, I can't see how you derive specific expectations for the CDATA node from that. *Any* added white space changes the output, so it if adding white space means that the document won't be correct, it is impossible to make a print function that is simultaneously pretty and correct.

This won't fix this problem as there still will be a text node before the "raw" element.

I think he means XPath normalize, which removes leading & trailing white space, as well as combining internal whitespace. This used to be a stand-alone function in Ft/Xml/Xslt/XmlWriter.py as well, but I think Jeremy or I merged it into TranslateCdataAttr. -- Uche Ogbuji Fourthought, Inc. http://uche.ogbuji.net http://4Suite.org http://fourthought.com A Python & XML Companion - http://www.xml.com/pub/a/2002/12/11/py-xml.html XML class warfare - http://www.adtmag.com/article.asp?id=6965 MusicBrainz metadata - http://www-106.ibm.com/developerworks/xml/library/x-thi nk14.html From dev-xml@smartology.nl Tue Dec 17 18:22:05 2002 From: dev-xml@smartology.nl (Remy C.
