[lxml-dev] Checking whether a node is a comment/element
by Geoffrey Sneddon 10 Apr '23

10 Apr '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/>

[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

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.

Hi, I've tried to build lxml from trunk today, on Win32. Got the following error: src\lxml\etree.c(880) : error C2059: syntax error : ')' src\lxml\etree.c(881) : error C2059: syntax error : ')' src\lxml\etree.c(882) : error C2059: syntax error : ')' src\lxml\etree.c(883) : error C2059: syntax error : ')' Any clue? Smells like a Pyrex issue? -- Sidnei da Silva Enfold Systems http://enfoldsystems.com Fax +1 832 201 8856 Office +1 713 942 2377 Ext 214

parser.feed w/ target not "immediate"
by Phil Mayers 14 Jun '14

14 Jun '14

(Bah sorry, hit wrong key) I'm using lxml to parse Junoscript, which is a protocol that's a single infinite XML document, a bit like XMPP. It goes: <junoscript> <pdu>...</pdu> <pdu>...</pdu> <pdu>...</pdu> I've been using the construct: parser = XMLParser(target=SomeClass()) while getdata(): parser.feed(data) ...and handling the start/end event callbacks to dispatch PDUs. I've run into problems in production where, all of a sudden, parser events aren't being dispatched when I expected. The difference seems to be the chunking of the data differs in production, for reasons of timing/load. I found this thread: http://thread.gmane.org/gmane.comp.python.lxml.devel/4871/focus=4881 ...which suggests this is actually expected, and my understanding of the parser/target stuff is wrong - there's no guarantee that "end" will be called at any particular time. Is this correct? Since it's an infinite document, I can't call ".close()". Does lxml have any API I can use to handle this, and that also has a push interface? Note I cannot let lxml read or block, since it's being used in an async fashion. I need to push the data in, and get notifications of tag start/end events as soon as the full open/close has happened. If lxml doesn't have this, can anyone recommend another parser? Cheers, Phil
