[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.

issue with findtext and find
by Tim Browski 29 Jul '15

29 Jul '15

Hi, For the following scenario find and find text cannot return the element. Is it intended functionality or a possible bug? <a> <c></c> </a> when element called with elm.find("b/c") or elm.findtext("b/c"), it returns None. However, when I call find with exact XPATH location it returns the expected result. Best, Tim

Weird (?) tree.getpath behaviour
by Gilles Lenfant 20 Jul '15

20 Jul '15

Hi, I use the "tree.getpath(element)" to solve a problem, and I need to have a meaningful path. In the example at http://pastebin.com/1Xjprfui the getpath method behaves exactly as expected when I use it in an XML doc with no namespace or if all elements have a namespace prefix (examples 1 and 3). But if I use tree.getpath(element) on a document with a default namespace (second example), I got weird getpath results like "/*", "/*/*/*[2]" and so on when I expected meaningful path like "/root", "/root/parent/child[2]". Is this a bug or a feature ? If a feature, is there some workaround to get meaningful path expressions ? Thanks in advance for any help. -- Gilles Lenfant

Hi I'm trying to iterate through the text content of a subtree using elt.itertext() (v3.5.0b1 git master branch) as follows: import lxml.html.soupparser as soupparser import requests doc = requests.get("http://f10.5post.com/forums/showthread.php?t=1142017").content tree = soupparser.fromstring(doc) nodes = tree.getchildren() for elt in nodes: for t in elt.itertext(): print t But I keep getting an error saying File "src/lxml/iterparse.pxi", line 248, in lxml.etree.iterwalk.__init__ (src/lxml/lxml.etree.c:134032) File "src/lxml/apihelpers.pxi", line 67, in lxml.etree._rootNodeOrRaise (src/lxml/lxml.etree.c:15220) ValueError: Input object has no element: HtmlComment Is there a way to skip all HTML comments? Also, what does this error actually mean? Any help will be appreciated. Thanks John
