[lxml-dev] setup on win32
by Slou Aug. 20, 2005

Aug. 20, 2005

Hi, here is patch that works for me (I have linux machine at home and windows xp at work). there should be added 'external' directory and contents of development versions of iconv, libxml2 and libxslt should be placed. I got them from http://www.zlatkovic.com/pub/libxml/ PS may be it's time to have some sort of bugtracking system to be installed? For example Trac (http://projects.edgewall.com/trac/) would be good I think.

[lxml-dev] ElementTree.dump() crashing the interpreter
by Steve Howe Aug. 18, 2005

Aug. 18, 2005

Hello all, As of lxml SVN revision 16125 (and other recent builds), this code is crashing the Python interpreter: from lxml import etree as ElementTree ElementTree.dump(ElementTree.Element('a')) This is happening on my Windows XP system: -- ActivePython 2.4.1 Build 245 (ActiveState Corp.) based on Python 2.4.1 (#65, Mar 30 2005, 09:33:37) [MSC v.1310 32 bit (Intel)] on win32 -- This also happens on other situations where I use ElementTree.tostring(), but I can't reproduce them on all times. I don't have access to a unix box right now, so I can't test on that platform. Any clues ? -- Best regards, Steve mailto:howe@carcass.dhs.org

[lxml-dev] xpath and ElementTree namespace notation
by Slou Aug. 17, 2005

Aug. 17, 2005

Hi, I see great inconsitence in lxml - that is nodes namespace handling. There are two aproaches right now: first one is taken from ElementTree ('{http://some.namespace/url/}node') and another that is used in .xpath method (using shorthands and map of shorthands to full urls). I think that the easiest and straight-forward solution is to cut off .xpath function and expand .find and .findall functions to accept XPath expressions as argument. This wouldn't break compatibility with ElementTree and will let to use all power of libxml in consistent way.

[lxml-dev] No output for tree.write
by Hamish Lawson Aug. 16, 2005

Aug. 16, 2005

The program below outputs the XML document as expected when run with (lxml 0.7, libxml2 2.6.16, libxslt 1.1.12, Python 2.3, Linux). But on (lxml 0.7, libxml2 2.6.16, libxslt 1.1.2, Python 2.3, Solaris 9) it produces no output. However "write_c14n" does work for the latter. **** template_source = """\ <html> <h1>Hello</h1> <p>2005</p> </html> """ from lxml import etree as elementtree from cStringIO import StringIO import sys template_file = StringIO(template_source) tree = elementtree.ElementTree(file=template_file) tree.write(sys.stdout) **** Hamish Lawson

Aug. 12, 2005

Hi together Just joined the list. Is there some information about to install lxml on a windows box? I like to participate on the Zope3/ECM wmfc development. But there seems no way to compile the lxml library on a win box.

To get dirty error reporting: Go to src/lxml/etree.pyx. Change the line DEBUG = False to DEBUG = True. libxml2 will now start to blabber way too much information at you. Another trick is to leave DEBUG = False, and simply spawn a thread, as the shutting up doesn't happen for all threads yet. :) Thanks for the offer to work on the windows installer! Note that if you want to work on a win32 installer, please read the mailing list archives, in particular this message: http://codespeak.net/pipermail/lxml-dev/2005-July/000290.html and post to the mailing list that you're volunteering on this. I have several other people who expressed interest in doing this already, and I'd prefer you guys to work together or at least determine among yourselves who will do all the work. I myself will just repeat to everybody who made it work on windows that I'm glad to get their contributions until we actually have a regularly updated windows installer. :) Regards, Martijn

[lxml-dev] lxml relaxng support
by Carlos Pita Aug. 9, 2005

Aug. 9, 2005

Hi all! I started using lxml because of its relaxng support. But: 1) does it parse relaxng compact syntax? 2) is there any way to get better error report (besides ok/error)? Btw, I've built win32 lxml binaries (which uses the libxml binaries located at http://www.zlatkovic.com/libxml.en.html). If anyone of you needs them just email me. Thank you in advance.
