[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

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] Building LXML Trunk

Hi, I've tried to build lxml from trunk today, on Win32.

[lxml-dev] Pickling objectified trees
by Christian Zagrodnick 09 Jun '08

09 Jun '08

Hi, the other day I had to pickle objectified trees. I just thought to share my findings. Pickling is about serialization. IMHO the natural serialization of an objectified tree is its XML representation. So the following basically does that: -------------------------- import copy_reg import lxml.etree import lxml.objectify def treeFactory(state): """Un-Pickle factory.""" return lxml.objectify.fromstring(state) copy_reg.constructor(treeFactory) def reduceObjectifiedElement(object): """Reduce function for lxml.objectify trees. See http://docs.python.org/lib/pickle-protocol.html for details. """ return (treeFactory, (lxml.etree.tostring(object), )) copy_reg.pickle(lxml.objectify.ObjectifiedElement, reduceObjectifiedElement, treeFactory) ----------------------------------------- You might consider just registering the reduce function in lxml itself. Shouldn't hurt, should it. -- Christian Zagrodnick gocept gmbh & co. kg · forsterstrasse 29 · 06112 halle/saale www.gocept.com · fon. +49 345 12298894 · fax. +49 345 12298891

[lxml-dev] lxml namespaces
by Maxim Sloyko 19 Feb '08

19 Feb '08

Hi All! I have a little problem with XML namespaces. In my application I have two XML processors, that process the same document, one after the other. The first one looks for nodes in 'ns1' namespace, and substitutes them, according to some algorithm. After this processor is finished, it is guaranteed that there are no more 'ns1' nodes left in the tree. 'ns1' namespace dclaration is still there, in the root node (well, I put it there manually). Now, when this namespace is no longer needed, I want to get rid of it, because it confuses some other processors (namely, my browser) So, the question is, how do I do that? del tree.getroot().nsmap['ns1'] does not seem to do the trick :( Thanks in advance and Happy Holidays! -- Maxim Sloyko

[lxml-dev] easy_install issues
by pf＠pfhawkins.com 04 Dec '07

04 Dec '07

I'm having trouble installing any version of lxml higher than 1.3.3. The error says that easy_install can't find a proper version of dateutil, even though I have a high enough version of "python-dateutil" installed on this system. I assume that the issue has to do with "dateutil" vs. "python-dateutil", but I'm not sure. FWIW, I'm running ubuntu gutsy. Thanks in advance! P. F.

[lxml-dev] Error (?) with UTF-8 document and Python unicode repr.
by Artur Siekielski 29 Nov '07

29 Nov '07

Hi. First of all, thanks for a great XML/HTML library! API is really good thought. I'm coming here with a problem with HTML doc encoded with UTF-8: $ cat test_doc.html <?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>A*?Ä?ka</title> <meta http-equiv="Content-Type" content="text/html; charset=utf-8" /> </head> <body> <h1>GdaA*?sk</h1> </body> </html> ("title" and "h1" contents are utf-8 strings, decodable to latin2). From raw Python everything seems to be as expected: >>> sdata = open('test_doc.html').read() >>> sdata[219:240] '<title>\xc5\x81\xc4\x85ka</title>' >>> udata = unicode(sdata, 'utf-8') >>> udata[219:240] u'<title>\u0141\u0105ka</title>\n ' >>> print udata[219:240].encode('latin2') <title>Łąka</title> The last statement prints as expected on my console with latin2 charset. But when using lxml something strange happens: >>> from lxml import etree >>> t = etree.parse(open('test_doc.html'), etree.HTMLParser()) Now getting title element text: >>> t.getroot()[0][0].text u'\xc5\x81\xc4\x85ka' This is strange, because this is a unicode string (as indicated by the first "u") but it's representation printed to console is the same as raw bytes from 'sdata' var. I would expect that it should be equal to contents to 'udata' var. As a consequence converting to latin2 doesn't work: >>> t.getroot()[0][0].text.encode('latin2') Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/share/python2.5/encodings/iso8859_2.py", line 12, in encode return codecs.charmap_encode(input,errors,encoding_table) UnicodeEncodeError: 'charmap' codec can't encode character u'\xc5' in position 0: character maps to <undefined> If it's not an error, please tell me. For now I cannot even find any reasonable workaround. I'm using the latest lxml 1.3.6. Thanks for looking at this problem, Regards, Artur

Hi all, lxml 2.0alpha5 made it to PyPI. This is (hopefully) the last alpha in the pre-2.0 series, so please report any remaining API quirks, weirdnesses and bugs now to make sure they get fixed before 2.0 gets its API freeze during the beta cycle. If all works out well, there should not be more than one beta release before the final version. This release features a major overhaul of the target parser, including an internal SAX parser framework and an ET compatible TreeBuilder implementation. The complete Changelog follows below. Note that the API now enforces keyword-only arguments in a couple of places. This can require some syntactic changes in existing code. Have fun, Stefan 2.0alpha5 (2007-11-24) Features added * Rich comparison of element.attrib proxies. * ElementTree compatible TreeBuilder class. * Use default prefixes for some common XML namespaces. * lxml.html.clean.Cleaner now allows for a host_whitelist, and two overridable methods: allow_embedded_url(el, url) and the more general allow_element(el). * Extended slicing of Elements as in element[1:-1:2], both in etree and in objectify * Resolvers can now provide a base_url keyword argument when resolving a document as string data. * When using lxml.doctestcompare you can give the doctest option NOPARSE_MARKUP (like # doctest: +NOPARSE_MARKUP) to suppress the special checking for one test. Bugs fixed * Target parser failed to report comments. * In the lxml.html iter_links() method, links in <object> tags weren't recognized. (Note: plugin-specific link parameters still aren't recognized.) Also, the <embed> tag, though not standard, is now included in lxml.html.defs.special_inline_tags. * Using custom resolvers on XSLT stylesheets parsed from a string could request ill-formed URLs. * With lxml.doctestcompare if you do <tag xmlns="..."> in your output, it will then be namespace-neutral (before the ellipsis was treated as a real namespace). Other changes * The module source files were renamed to "lxml.*.pyx", such as "lxml.etree.pyx". This was changed for consistency with the way Pyrex commonly handles package imports. The main effect is that classes now know about their fully qualified class name, including the package name of their module. * Keyword-only arguments in some API functions, especially in the parsers and serialisers.
