Hi all, I added the lxml project to launchpad, the Ubuntu Bug-Tracker. It also has a FAQ engine and a couple of other goodies. https://launchpad.net/lxml It's easy to sign up for launchpad, BTW, no 90%-footnotes-contract. Have fun, Stefan

[lxml-dev] Reparenting a node
by Lawrence Oluyede 30 Jan '23

30 Jan '23

I have a doc A and a doc B, I'd like to put a node extracted from A in the document B but I always get a ValueError: ValueError: Element is not a child of this node. I didn't find any "setparent" in the API. How can I do this? -- Lawrence, oluyede.org - neropercaso.it "It is difficult to get a man to understand something when his salary depends on not understanding it" - Upton Sinclair

Canonicalization of PROV-XML Documents fails
by Steven 30 Jan '23

30 Jan '23

Hey everyone, i want to canonicalize Prov Documents, which are encoded according to the PROV-XML Scheme (https://www.w3.org/TR/prov-xml/). I used the etree.canonicalize method with the following XML document: https://openprovenance.org/store/documents/5763.xml . Unfortunately the order of elements remains unchanged. I tried to pass the XML via file and via string - but the cancolized document look unchanged. Does lxml cant deal with XML-Extensions?

Good way to remove/catch wrong tags?
by codecomplete＠free.fr 28 Jan '23

28 Jan '23

Hello, Some columns in a DB have badly formed HTML, to the point BeautifulSoup (lxml?) fails: ============= #Some records start with 0A</crap> soup = BeautifulSoup("\n</strong>", 'lxml') #AttributeError: 'NoneType' object has no attribute 'text' print(soup.body.text) ============= What would be a nice way to solve the problem? Is there a command to remove wrong tags altogether (eg. strings that starts with </strong>), or should I just catch the error? Thank you.

[lxml-dev] Checking whether a node is a comment/element
by Geoffrey Sneddon 11 Jan '23

11 Jan '23

Hi, What's the best way to check whether a given node is a comment or an element? For the former, I'm currently using isinstance(node, etree._Comment), which is rather obviously sub-optimal. -- Geoffrey Sneddon <http://gsnedders.com/>

by Stefan Behnel 11 Jan '23

11 Jan '23

Hi all, lxml 2.0.5 is on PyPI. This is a bug-fix-only release of the stable 2.0 series. Have fun, Stefan 2.0.5 (2008-05-01) Bugs fixed * Resolving to a filename in custom resolvers didn't work. * lxml did not honour libxslt's second error state "STOPPED", which let some XSLT errors pass silently. * Memory leak in Schematron with libxml2 >= 2.6.31.
