[lxml-dev] Test case that triggers assertion in lxml
by Stefan Behnel Nov. 3, 2005

Nov. 3, 2005

This test case triggers an assertion in lxml.etree: def test_iteration5(self): XML = self.etree.XML root = XML('<doc><one/><two>Two</two>Hm<three/></doc>') result = [] for el in root: result.append(el.tag) del root[-1] self.assertEquals(['one', 'two'], result) Output: Proxy: <etree._ElementIterator object at 0x40347920> Proxy type: 3 Exception exceptions.AssertionError: 'Tried to unregister unknown proxy' in 'etree.unregisterProxy' ignored Looks like it unregisters the iterator proxy when its element is GCed. While it is an interesting idea to have the iterator be itself an Element, I wonder if this is viable if you try to avoid such problems. Stefan

[lxml-dev] a patch for setup.py when libxml2 and libxslt are built to separate dir
by Trent Mick Nov. 3, 2005

Nov. 3, 2005

Hello, I'm just starting to play with lxml and am quite pleased with it so far. Thank you for creating it. I have a small patch for setup.py that, if people think is reasonable, I'd like to see applied to lxml repo. Although probably not typical, one can build libxml2 and libxslt to separate directories. Say something like this: ~/opt/libxml2-2.6.22/... ~/opt/libxslt-1.1.15/... In that situation libxml2's "xml2-config" does not know how to return the proper compilation and link flags for both libxml2 and libxslt. However, libxslt (which depends on libxml2, of course) knows how: $ xml2-config --cflags -I/Users/trentm/opt/libxml2-2.6.22/include/libxml2 $ xslt-config --cflags -I/Users/trentm/opt/libxslt-1.1.15/include -I/Users/trentm/opt/libxml2-2.6.22/include/libxml2 My patch (see attached) changes guess_dirs() to use xslt-config. What do you think? Trent -- Trent Mick trentm(a)gmail.com

[lxml-dev] Python interpreter segfault setting element tail
by Kieran Holland Nov. 3, 2005

Nov. 3, 2005

Thanks for lxml - very nice. Unfortunately the following fragment causes my python interpreter to crash and burn: ---------------- from lxml import etree root = etree.fromstring('<html><p></p>x</html>') for elem in root: elem.tail = '' ----------------- System: gentoo linux 2004.3 on x86 python 2.4.1 lxml 0.7 (and 0.6) libxml 2.6.19 Kieran
