From rsalz@datapower.com Fri Nov 1 17:22:27 2002 From: rsalz@datapower.com (Rich Salz) Date: Fri, 01 Nov 2002 12:22:27 -0500 Subject: [XML-SIG] Anyone want to be a maintainer? Message-ID: <3DC2B853.3070806@datapower.com> Does anyone want to maintain the xml-sig mailing list? It's run by mailman, of course, so it generally means you get one or two messages/week saying that someone has been removed for bounces. And then every other week or so there are the occasional non-member spam messages to bounce. It's really low overhead; I'm quite happy to keep doing it. I'm asking because along with that comes the privilege of maintaining the xml-sig web pages at python.org. When I first started I tweaked some words, removed some outdated references, but they've really languished for some time. My day job is no longer involved with Python and XML, so I don't have the time or energy (nor skill, frankly) to make the xml-sig web pages properly indicative of the rip-roarin' dynamic group that it should be. So, if you want commit access to www.python.org and would take pleasure in bit-bucketing the random spam, let me know. /r$ From fred@computronix.com Fri Nov 1 18:28:13 2002 From: fred@computronix.com (Fred Moscicki) Date: Fri, 1 Nov 2002 11:28:13 -0700 Subject: [XML-SIG] ConfigParser.py Message-ID: <27D23C54DCE5E743B5500C5295A73022D769D0@ALPHA.computronix.com> This message is in MIME format.

That doesn't sound good to me, but I noticed you were using 4DOM, which I don't normally use. I decided to try your test with minidom instead, and got very different results. I changed your script to allow the parseString function to be passed in to doTest(), and added an import and a second call to doTest: from xml.dom import expatbuilder doTest(100, s1, expatbuilder.parseString) I got this output: parser performance test 100 parses took 7.44 seconds, or 0.07 seconds/parse 100 parses took 0.47 seconds, or 0.00 seconds/parse (The first measurement is the original 4DOM DOM builder, and the second is the expatbuilder.) I've attached the modified script. > Is there anything I can do to make this code faster? Appearantly, use minidom instead of 4DOM.

If you want _another_ factor of 10, go to PyLTXML. The report below is from Python 2.2.1 on RedHat Linux 7.2 using PyXML 0.8.1 and PyLTXML-1.3-2.

So is the resulting object compliant (or at least close) to the Python DOM, as defined in the Python Library Reference? http://www.python.org/doc/current/lib/module-xml.dom.html (Lazy building of structures is fine, of course, since that's implementation.) If it doesn't support the DOM API, does it support something with an equivalent model and functionality? > Here are the additions I made to Fred's version of the script: ... > def allBits(s): > f=PyLTXML.OpenString(s1,PyLTXML.NSL_read|PyLTXML.NSL_read_namespaces) > b=PyLTXML.GetNextBit(f) > while b: > b=PyLTXML.GetNextBit(f) > PyLTXML.Close(f) > > def itemParse(s): > f=PyLTXML.OpenString(s1,PyLTXML.NSL_read|PyLTXML.NSL_read_namespaces) > b=PyLTXML.GetNextBit(f) > while b.type!='start': > b=PyLTXML.GetNextBit(f) > d=PyLTXML.ItemParse(f,b.item) > PyLTXML.Close(f) > return d Ouch!

Loewis writes: > I like it (obviously): errors should never pass silently, unless > expliclitly silenced. I agree. The real difference between the W3C idea of getDOMImplementation() and the one we're using is in whether not getting an implementation for some particular feature set is an error. See Ray Whitmer's response to my questions about this on the www-dom list: http://lists.w3.org/Archives/Public/www-dom/2002OctDec/0108.html Which is the "right" thing is rightly very application-specific. For the W3C flavor of this, there's no such thing as "just gimme a DOM"; you always ask for some specific set of features, and the application can reasonably say "ok, that didn't work, let's try a reduced feature set and offer reduced functionality" (where any decent application will be able to tell the user if it makes sense to do so). As I consider in my response to Ray's comments: http://lists.w3.org/Archives/Public/www-dom/2002OctDec/0109.html the right approach may be to have a second function (either somewhere else or with a different name) that does implement the W3C API for this, but the overloading of the name may well not be the right way to go about this. -Fred -- Fred L.

Here I strongly disagree: If we have a function getDOMImplementation, then people *will* expect this to be the W3C function, regardless of the documentation saying that we have renamed this function. If people think that it would really be better to return None instead of raising an exception if no implementation can be found, I'd say that it is acceptable to break the API here: Few people will be affected, IMO, and they can readily support multiple versions: try: impl = xml.dom.getDOMImplementation(features) except ImportError: impl = None if impl is None: process error Regards, Martin From tpassin@comcast.net Wed Nov 6 00:28:17 2002 From: tpassin@comcast.net (Thomas B.

However, I would really like to see that any code actually breaks under this change. We can change it in PyXML, and if anybody complains, we can change it back quickly and reconsider. Most likely, nothing breaks: all callers of getDOMImplementation arrange the arguments so that they know it will succeed.

I believe so -- our model actually _predates_ the DOM, and we've never had the time/resources to roll it forward, but it was of course solving the same problem. The documentation lists the following Python object types: FileType DoctypeType ElementTypeType ContentParticleType AttrDefnType BitType ItemType OOBType ERefType QueryType These correspond to the xml.dom objects as follows, I think: FileType * 13.6.2.1 DOMImplementation Objects ItemType * 13.6.2.2 Node Objects python tuple * 13.6.2.3 NodeList Objects DoctypeType * 13.6.2.4 DocumentType Objects FileType * 13.6.2.5 Document Objects ItemType * 13.6.2.6 Element Objects not exposed * 13.6.2.7 Attr Objects not exposed * 13.6.2.8 NamedNodeMap Objects OOBType * 13.6.2.9 Comment Objects ItemType * 13.6.2.10 Text and CDATASection Objects OOBType * 13.6.2.11 ProcessingInstruction Objects The details are in the documentation which comes with the source distribution, which uses distutils and is GPL-click-wrapped at http://www.ltg.ed.ac.uk/software/xml/ To avoid hassle, you'll want the source and the appropriate binary distribution at a minimum -- actually _building_ the extension requires an LT XML installation as well. ht -- Henry S.

Python does use Xerces, see http://sourceforge.net/projects/pirxx/ > (Perl port is done there, too.) What's the main difference (design > goal, performance, license, etc.) between PyXML and Xerces? Well, Xerces is for C++, PyXML is for Python; this is the main difference. PyXML tries to integrate all sorts of XML technology into Python, both existing one and new one. As for Xerces specifically: PyXML offers a variety of XML parsers, depending on application needs. It also offers a variety of APIs for parsing (again depending on application needs).

Hi,
 
I wrote some code using pyxml 7.  I used code such as:
 
    a_Node = xml.dom.minidom.Text("data");
 
This works fine in 7.
 
When I tried to upgrade to pyxml 8, it says I could no longer create a text node this way.  Is there a way around this?

That Text had an __init__ was an implementation detail, which was not documented and not supposed to be used. OTOH, createTextNode was documented all the time, both in the Python documentation, and the W3C DOM specification.

Wrap up any Expat issues remaining (me). 2. Release the next version of Expat (me). 3. Update the Expat code in PyXML (me). 4. Release PyXML 0.8.2 (Martin? please? ;). 5.

How exactly are you invoking the transformation? If you have a Processor instance proc, and you are calling, e.g. proc.runStream(str) then you can simply add the keyword argument topLevelParams with a dictionary of parameters as its value. For example: result = proc.runStream(str, topLevelParams={'page': 27}) If that doesn't address your need, perhaps you could post a sample of your code. -- Matt Gushee When a nation follows the Way, Englewood, Colorado, USA Horses bear manure through mgushee@havenrock.com its fields; http://www.havenrock.com/ When a nation ignores the Way, Horses bear soldiers through its streets. --Lao Tzu (Peter Merel, trans.)

BTW, your example is wrong in either case because the empty namespace is None, not '' (I suggest always using xml.dom.EMPTY_NAMESPACE.

In a fit of curiousity, I went to 4Suite 0.11.1 and pulled out this old snippet from Stylesheet.prime: for k in topLevelParams.keys(): if type(k) != types.TupleType: try: split_name = Util.ExpandQName(k, namespaces=context.processorNss) except KeyError: continue else: split_name = k overridden_params[split_name] = topLevelParams[k] Ah, nostalgia. :-) That having been said, "It has always been this way" is no reason it cannot change. Perhaps we can expect more sophistication from a user of the Processor API than we can a Web or command-line user. But even after a bit of though, I'm not inclined right away to make things more restrictive. -- Uche Ogbuji Fourthought, Inc. http://uche.ogbuji.net http://4Suite.org http://fourthought.com Python&XML column: 2.

David Mertz (mertz@gnosis.cx) Frank McIngvale (frankm@hiwaay.net) ------------------------------------------------------------------------ DIGRESSION: A user proposed improvements to gnosis.indexer to enable word-stemming and positional indices. The latter would enable proximity searches, although that is not yet implemented. I find the proposed code, however, in need of a bit of refactoring, and I have not tested it. If anyone wants this code to play with, let me know; if anyone with more time than me wants to take on the actual refactoring and testing, I would be overjoyed. -dqm ------------------------------------------------------------------------ BACKGROUND: Gnosis Utilities contains a number of Python libraries, most (but not all) related to working with XML. These include: gnosis.xml.pickle (XML pickling of Python objects) gnosis.xml.objectify (Any XML to "native" Python objects) gnosis.xml.validity (Enforce validity constraints) gnosis.xml.indexer (XPATH indexing of XML documents) gnosis.indexer (Full-text indexing/searching) [...].convert.txt2html (Convert ASCII source files to HTML) gnosis.util.dtd2sql (DTD -> SQL 'CREATE TABLE' statements) gnosis.util.sql2dtd (SQL query -> DTD for query results) gnosis.util.xml2sql (XML -> SQL 'INSERT INTO' statements) gnosis.util.combinators (Combinatorial higher-order functions) gnosis.util.introspect (Introspect Python objects) ...and so much more! :-) SUMMARY:

If I write simple code like: read_channel = self.socket.makefile('r') reader = Sax2.Reader() reply = reader.fromStream(read_channel) The fromStream method is stalled even after a complete XML element was read because it waits for the channel to close.
