My inclination would be to only include the lib/ directory, at least for the 1.95.x (and I think 1.95.2 is a good update candidate! ;) versions. The directory structure has changed between 1.2 and 1.95.x, so that this is reasonable. Nothing from the xmlwf/ directory should be needed. -Fred -- Fred L.

The relationship of xslt and xpath is the other way 'round: the XPath expression parser can also parse XSLT patterns. For that, it imports ParsedPattern etc; perhaps it should just ignore patterns if it cannot import the patterns classes.

Initial Comment: We are using here version 11.1beta3 of 4XSLT on RedHat 6.2 operating system and I've just found something that looks like a bug: Consider this very simple xml file: and this xslt file:

* *

After transforming the XML file with this XSL Transformation, I should get something like: ...

...

* *

... Thus the character which should be always replaced with is considered as a space character and is only displayed if the string contains another non-space character (e.g. *). This is quite annoying because is widely use in HTML to have empty coloured cells in a table. Regards, O.

It's irrelevant where you untar the distribution; it could have been in /tmp. However, when you invoked "python setup.py install", which copy of Python did you get? You can find out by saying "which python". If the answer is "/usr/bin/python", or "/usr/local/bin/python", then that is the problem - you should use the Python installation in your account. > I poked around in my Python install and found a folder "distutils" in > Python-2.1.1/Lib that contained a file core.py, but that doesn't seem > right (shouldn't it be in the Modules folder?).

Reviews of multiple books, as when DDJ reviews 5 books in a column, or Yee reviews all the books in a trilogy or series. I'd wrap up (title,author+) in an 'item' element, a good generic name. Also, I'd like to have 'review' be the root element of the DTD, meaning one review = one document. However, because no one defines how validation works in the presence of namespaces, you can still have documents that contain multiple reviews. --amk From israel@lith.com Mon Aug 20 21:33:38 2001 From: israel@lith.com (Israel Evans) Date: Mon, 20 Aug 2001 13:33:38 -0700 Subject: [XML-SIG] Newbie requesting guidance, or directions to guidance..., a map, a hint, a sly wink of the eye...

I'm currently implementing a Web-based XML editor in Python using the Python XML package (mainly for the DOM stuff). Thanks a lot to its developers, it's a great package! Now, the editor needs to know at which node it may insert which other nodes, which nodes it has to insert because they are required etc. etc. So I need to parse the DTD. Or the Schema. I decided to go for the latter, because as soon as XSchema matures, DTDs will likely become obsolete step by step. BTW, XSchema allows more complex specification of XML structure and content grammar. I have browsed the web for a Python-based XSchema Parser, but so far, I have not found anything. So I started to work on an own parser and I'm coming along quite nicely (after all, it's Python! :-). It doesn't do that much, but it will soon. I do that work for the company I work in (warptec) and I do not know whether I'm allowed to 'Free' the XSchema parser, but I have given some strong arguments to my boss. It will be decided within a couple of days. I won't promise anything. But chances are good that I may put it under a free license and contribute it to the PyXML project. My question is: Do you want that code, after all? Do you think a schema parser makes sense for the project and be something which should be part of the PyXML project?

This looks in the registry under HKEY_LOCAL_MACHINE\Software\Python\PythonCore\x.y\InstallPath to find the location where Pythin is installed. (x.y is the required version 2.0, 2.1, whatever). This registry key is created by the installer when you install Python itself. If you compiled it from source, it will not be present. Could you look for this entry with the registry editor?

They are documented here: The documentation has followed the Java SAX 2.0 API, but I think the default for feature_validation should be the opposite of what that page says. The default SAX parser you get in Python is the expat driver, and for this property it has the opposite value of that documented. That is bound to confuse people, and so I think we should change the documentation. There is also feature_external_pes which I don't know what expat does with. Does the expat version we have now read external parameter entities? If not, we should either change that or the documentation. The best is, I think, to change the implementation, but if that proves difficult we should change the documentation. The feature_namespaces feature is also troublesome. Part of the point behind splitting the startElement event into startElement and startElementNS was to make SAX easier to use for novices. If that is to have any point the default has to be that namespace processing is off. This is also what expatreader.py and drv_xmlproc.py implement at the moment. I think we should change the documentation to reflect this. Comments, anyone? --Lars M.

Which type of parsing will work e.g. parsing to DOM and proxying to Python, SAX? I'm wondering because I would love to special-case Xerces DOMs as an input type in Pyana (1). Also, Pyana, for DOM output, generates and proxies a Xerces DOM (2). It would be great if the user could hand that to PIRXX for further processing (e.g. for validation). The problem is that we can only do these kinds of things (with any degree of safety) if we merge the two extensions into one binary. Is that something that we should discuss? (1) Pyana is a Python interface to the Xalan XSLT processor. docs: http://pyana.sourceforge.net/docs/ sourceforge: http://sourceforge.net/projects/pyana (2) Not checked-in to CVS yet.

For starters, SAX parsing via a Python SAX2 driver. What will follow is SAX bridges (feeding C++ SAX into Python is part of = the SAX driver already, feeding Python SAX into a C++ handler will be possible too). A DOM wrapper is also planned. In a nutshell, the original goals still hold true (note the last point):= - Make Xerces available as a PyXML parser (make_parser interface) - Bridge between Python and C++ SAX streams - Wrap Xerces DOM in a way compatible to 4DOM - Wrap the XalanTransformer class, then adapt to common Python interfaces on that basis - Provide an interface to XSLT extension functions written in Python= (code for that is already existing at WEB.DE AG) - Coordinate efforts with Pyana >The problem is that we can only do these kinds of things (with any >degree of safety) if we merge the two extensions into one binary.

ZSI was designed to work with *pre-existing* transports, such as Apache (such as through mod_python which is what we do), Python's HTTPServer (the release includes the server I use for SOAP interop testing), or sys.stdin, sys.stdout (which the docs show). Any object with a read method can be used for input, and anything with a write method can be used for output.

Please take a look at the ZSI doc; if it doesn't do what you want, I'm probably quite willing to add what's missing. ZSI is at http://www.zolera.com/resources/opensrc, including PDF and HTML doc separate from the kit.

You have to do something like convert them to a canonical form and compare those. Luckily :), pyxml (the CVS version, not yet the released version) has XML C14N code. You can rip that out and use it stand-alone. (Shameless plug) you can also find it on the W3C web site, look for XML Digital Signature.

There are a couple of reasons for that. First, I wanted to get some feedback on usage models before "blessing" one particular style. It's also a result of my transport-neutral approach; ZOPE's dispatch style is probably different from a dynamic application gateway, which is different from a dedicated apache-based web service, etc. > >From a pedagogic point of view, may I suggest you start your > documentation with a SOAP "hello world."

Welll... I suppose I could do something like that. :) I do have a couple of questions, tho. What if there is data in the sent <hi> element? Is that parsed and passed as parameters to the hi() method? Which must then check for parameters, or ignore them? That is, can I do <S:Body><hi><p1>you stinking</p1><foo>mongrel</foo></hi></S:Body> ? It turns out, I believe, that SOAP::Lite won't actually be able to parse that message. It requires the SOAP message to be fully typed. But if it *could* parse it, I assume the p1 and foo parameters would somehow be made available (as a dictionary?) to Demo::hi. But suppose hi takes no parameters? Does Demo::hi have to error-check and be ready to generate faults? More on this below... I'm headed somewhere. > I'm trying to work up a talk on how EASY it is to work with SOAP in > scripting languages. It's easy to be loose and sloppy, but I think it's actually hard to do the right thing. SOAP in RPC mode is really strongly-typed, and that makes an interesting mix when you work with loosely-typed scripting languages. ZSI is different from other scripting SOAP implementations -- it seems to be the only Python one that can work with typed and -- if you have a "schema," in the form of ZSI "typecodes" -- completely untyped messages. ZSI enforces type-correctness at th SOAP message level. If you want the "hi" method <hi>...</hi> to take any kind of parameter, you must explicitly say "TC.Any()" and ZSI will try interpret the message (provided it contains type information) or raise an "Unparseable message" exception. "Python ZSI" is intended to evoke "Java RMI", on purpose. > I'll try to boil your example down to the barest > essence and see how close it gets to SOAP::Lite. :-) Attached is something that I could add to ZSI. I think it works like the SOAP::Lite dispatcher, or as close as it can without using 'eval' :) Not tested, but byte-compiled. /r$ -- Zolera Systems, Securing web services (XML, SOAP, Signatures, Encryption) http://www.zolera.com --------------2ED5E5B62C8B18B8FA985AC0 Content-Type: text/plain; charset=us-ascii; name="cgizsi.py" Content-Transfer-Encoding: 7bit Content-Disposition: inline; filename="cgizsi.py" #! /usr/bin/env python '''Simple CGI dispatching for ZSI.

Then you may want to give a try to XMLdiff available at http://www.logilab.org/xmldiff/ The current version has a slight algorithm complexity problem which makes it unusable for medium to large documents, but we are working on another algorithm that we should be releasing by the end of the week which dramatically improves the performance on big documents (at the cost of having a slightly less optimal output).

The problem is that the Printer class will convert the data from utf-8 to latin-1 twice for attributes : if you give a look at the visitAttr method, it first calls TranslateCdata (which does the first conversion), and then _write which attempts to convert the code again, resulting in the exception being raised.

From Juergen Hermann" Hi! When you checkout "test" on win32, you run into problems because someone checked this in without -kb, though all the text files have windows (CRLF) line endings. This also means that e.g. "a_oasis-logo.gif" is totally broken. I propose an "cvs admin -kb" on that tree. BTW, someone should put a README into the root of "test", describing what those directories contain.

Are there any features of 4xslt that you need that aren't available in other XSLT processors? Or is it just the convenience of doing XSLT transformations directly in Python that leads you to want to use 4xslt? If it is the later, Python buildings for Xalan, the Apache groups XSLT processor, are available (the Windows release has the most convenient installation process, if you have a choice of platforms to experiment with): http://sourceforge.net/project/showfiles.php?group_id=28142&release_id=4 7388 Documentation: http://pyana.sourceforge.net/docs/ If you are willing to send me your XML and XSLT files then I can do the transformation with Xalan and tell you how long it takes.

Yep. Most transformation engines have pretty bad startup times. Though if your transformations are taking >10 seconds it probably doesn't matter. Xalan has a bit slower transformation speed than Saxon but has a horrible startup time (probably because it is so huge). Running it in-process solves that problem, of course. > I haven't used Xalan for a while and have been meaning to get the latest > versoin to try on this. The Python binding might be good to try. Thanks. The Python bindings are for Xalan 1.1. The CVS version works correctly with Xalan 1.2 but hasn't been extensively tested. I can send you a binary if you are interested. Cheers, Brian
