[lxml-dev] Building LXML Trunk
by Sidnei da Silva Aug. 31, 2022

Aug. 31, 2022

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

[lxml-dev] Pickling objectified trees
by Christian Zagrodnick June 9, 2008

June 9, 2008

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 Feb. 20, 2008

Feb. 20, 2008

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] python crashes in xmlDictFree inside Zope
by Eric Tiffany June 4, 2007

June 4, 2007

I have been prototyping some XMLSchema parsing/validating using lxml 1.3beta. Everthing works great from python 2.4.4 started from the command line, or running from inside Eclipse. However, when I moved my code over to my Plone product, python crashes when Zope is initializing the product. I am creating my XMLSchema object there. THe code is essentially the same, running under the same python and with the same libs (afaik). Some earlier attempts (with python 2.4.3) gave me this error: python(11139) malloc: *** Deallocation of a pointer not malloced: 0x80; This could be a double free(), or free() called with the middle of an allocated block; Try setting environment variable MallocHelp to see tools to help debug I'm not seeing that now, as I have "upgraded" to python 2.4.4 which seems to be stripped or something. I don't have a test case immediately available, but here is the stack backtrace from the python crash log: OS Version: 10.4.9 (Build 8P2137) Report Version: 4 Command: Python Path: /opt/local/Library/Frameworks/Python.framework/Versions/2.4/Resources/Python .app/Contents/MacOS/Python Parent: bash [11055] Version: 2.4a0 (2.4alpha1) PID: 11135 Thread: 0 Exception: EXC_BAD_ACCESS (0x0001) Codes: KERN_PROTECTION_FAILURE (0x0002) at 0x00000001 Thread 0 Crashed: 0 libxml2.2.dylib 0x033f6294 xmlDictFree + 45 1 libxml2.2.dylib 0x033f62e2 xmlDictFree + 123 2 libxml2.2.dylib 0x033f62e2 xmlDictFree + 123 3 etree.so 0x06406a08 __pyx_f_5etree_14_ParserContext_initThreadDictRef + 63 (etree.c:19725) 4 etree.so 0x06406a5b __pyx_f_5etree_14_ParserContext_initParserDict + 35 (etree.c:19740) 5 etree.so 0x06431bca __pyx_f_5etree_11_BaseParser__parseDocFromFile + 99 (etree.c:21340) 6 etree.so 0x0646a8f4 __pyx_f_5etree__parseDocument + 395 (etree.c:22486) 7 etree.so 0x0646cc50 __pyx_f_5etree_parse + 176 (etree.c:10300) 8 org.python.python 0x0027faca PyEval_EvalFrame + 22777 (ceval.c:3568) 9 org.python.python 0x00280665 PyEval_EvalCodeEx + 1774 (ceval.c:2741) 10 org.python.python 0x0027e49f PyEval_EvalFrame + 17102 (ceval.c:3661) 11 org.python.python 0x00280665 PyEval_EvalCodeEx + 1774 (ceval.c:2741) 12 org.python.python 0x0027e49f PyEval_EvalFrame + 17102 (ceval.c:3661) 13 org.python.python 0x0027ebaa PyEval_EvalFrame + 18905 (ceval.c:3651) 14 org.python.python 0x0027ebaa PyEval_EvalFrame + 18905 (ceval.c:3651) 15 org.python.python 0x0027ebaa PyEval_EvalFrame + 18905 (ceval.c:3651) 16 org.python.python 0x0027ebaa PyEval_EvalFrame + 18905 (ceval.c:3651) 17 org.python.python 0x0027ebaa PyEval_EvalFrame + 18905 (ceval.c:3651) 18 org.python.python 0x0027ebaa PyEval_EvalFrame + 18905 (ceval.c:3651) 19 org.python.python 0x0027ebaa PyEval_EvalFrame + 18905 (ceval.c:3651) 20 org.python.python 0x0027ebaa PyEval_EvalFrame + 18905 (ceval.c:3651) 21 org.python.python 0x0027ebaa PyEval_EvalFrame + 18905 (ceval.c:3651) 22 org.python.python 0x00280665 PyEval_EvalCodeEx + 1774 (ceval.c:2741) 23 org.python.python 0x002808a5 PyEval_EvalCode + 87 (ceval.c:490) 24 org.python.python 0x002a75fd PyRun_FileExFlags + 200 (pythonrun.c:1285) 25 org.python.python 0x002a78e0 PyRun_SimpleFileExFlags + 640 (pythonrun.c:869) 26 org.python.python 0x002b13ec Py_Main + 3199 (main.c:493) 27 org.python.python 0x00001fae 0x1000 + 4014 28 org.python.python 0x00001ed5 0x1000 + 3797 Thread 0 crashed with X86 Thread State (32-bit): eax: 0x00000000 ebx: 0x033f6275 ecx: 0x00000000 edx: 0x00000000 edi: 0x00000001 esi: 0x05856fd0 ebp: 0xbfffcfe8 esp: 0xbfffcfb0 ss: 0x0000001f efl: 0x00010286 eip: 0x033f6294 cs: 0x00000017 ds: 0x0000001f es: 0x0000001f fs: 0x00000000 gs: 0x00000037 Binary Images Description: 0x1000 -

[lxml-dev] html branch
by Ian Bicking June 4, 2007

June 4, 2007

I've started a branch with lxml.html, in http://codespeak.net/svn/lxml/branch/html It currently includes: lxml.doctestcompare: XML/HTML doctests lxml.usedoctest: enable the doctest from within a doctest lxml.html.usedoctest: enable the doctest, using the HTML parser lxml.html: * lxml.html.HtmlMixin, defining on each element: - remove_element: element removes itself from a tree - remove_tag: element removes itself but not its children from a tree - find_rel_links: find <a rel="?"> - find_class: find <* class="?"> * HTML: parser * parse_elements: parse fragment, return list of elements * parse_element: parse fragment, return single element * Element: apparently a highly broken element factory (segfaults?!) * tostring: HTML serialization lxml.defs: lists of HTML tags (e.g., block_tags) lxml.clean: clean Javascript and other problem code from HTML lxml.rewritelinks: change the links in a document lxml.htmldiff: make human-readable diffs and blame reports The usedoctest modules are based on a really horrible hack. It seems to work, except for some reason lxml/html/tests/test_clean.txt is sometimes run without the doctest change. The other doctests aren't run like this, and when you explicitly run the test (e.g., python test.py test_clean) it runs fine. So something weird with the test runner, I guess. -- Ian Bicking | ianb(a)colorstudy.com | http://blog.ianbicking.org | Write code, do good | http://topp.openplans.org/careers

[lxml-dev] unittest.main()
by Ian Bicking May 30, 2007

May 30, 2007

I noticed many tests have: if __name__ == '__main__': unittest.main() But this seems to ignore test_suite(), so it's not really very useful. This seems more helpful: if __name__ == '__main__': print 'to test use test.py %s' % __file__ -- Ian Bicking | ianb(a)colorstudy.com | http://blog.ianbicking.org | Write code, do good | http://topp.openplans.org/careers

[lxml-dev] matches()
by Ian Bicking May 29, 2007

May 29, 2007

Using lxml trunk: doc.xpath('descendant-or-self::*[starts-with(lower-case(@href), "javascript:")]') works, but: doc.xpath('descendant-or-self::*[matches(@href, "^javascript:", "i")]') Returns ["i"]. This does not seem right...? -- Ian Bicking | ianb(a)colorstudy.com | http://blog.ianbicking.org | Write code, do good | http://topp.openplans.org/careers

[lxml-dev] lxml 1.3 - or 2.0?
by Stefan Behnel May 29, 2007

May 29, 2007

Hi all, I'm currently thinking about what should be changed or fixed for lxml 2.0, a preliminary list is at the end of TODO.txt. As fixing the entity handling would visibly change the way parsers behave (more exceptions, stricter parsing, etc.), maybe this would rather go into that list. This is what I have for now: * reformat error log lines, add column number * always use '<string>' as URL when tree was parsed from string? (can libxml2 handle this?) * clean up (and remove?) duplicated API for extension functions * find a way to integrate Schematron (if it's available) * always use ns-prefixed type names in objectify's ``xsi:type`` attributes * remove ``findOrBuildNodeNs()`` from C-API (replaced by findOrBuildNodeNsPrefix) * lxml.html (Ian?) * clean support for entities (maybe an Entity element class?) * follow PEP 8 in API naming (avoidCamelCase in_favour_of_underscores) The list of trunk changes since 1.2.1 is already pretty long, and there were some major changes under the hood (even since 1.3beta), e.g. the namespace cleanup code, XSD type prefixing in objectify, exception messages, etc. Hence, I'm actually considering to skip the 1.3 release and to rather start working on 2.0 directly, so that we could have an alpha version soon. Maybe some more bug fixes could be backported into a 1.2.2 first, so that people can work with it, but a 1.3 would mean "new features". I would like to have the freedom to break a few things here in order to make their API cleaner. And that means 2.0, not 1.3. Comments? Stefan

[lxml-dev] Entity handling in lxml
by Stefan Behnel May 27, 2007

May 27, 2007

Hi all, lets make this a new thread to discuss the topic that was raised by Eric Garin. The parsers in lxml are currently configured to replace entity references (&entity;) by their definition. This requires a DTD, either inside the document, as external URL reference or from the system catalog. The parsers do not currently load DTDs by default, neither do they do validation. So, the current situation is: 1) If you use the default parser, all entities will pass through without exception, but put an error message in the error_log: entity.xml:5:ERROR:PARSER:WAR_UNDECLARED_ENTITY: Entity 'oneXXX' not defined They will not be visible at the API level, they will cut off text that contains them ("my &entity; value" will result in a text property value "my "), but they will be serialised correctly. They may also break a lot of things internally, as the implementation is not prepared for dealing with stuff like entity reference nodes. 2) If you configure a parser to load the DTD, declared entities will be replaced and undeclared entities will behave as above. 3) If you configure a parser to validate against a DTD, it will still behave exactly as above. This behaviour is definitely a bug. It would be cleaner to do this: 1) The default parser should replace internally defined entities and report all other entities as an error. 2) A parser that loads the DTD should report undeclared entities as an error (although it would not do any validation). 3) A validating parser should report undeclared entities as an error, just as any other structural or semantic deviation from the DTD. The alternative would be to provide an API for entities and to rewrite the internals to deal with them somehow. We could potentially make entity references a sort of element that behaves more or less like a comment. Entities would mainly have a name and a tail. We would then need an Entity() factory and integrate entity reference nodes into the internal traversal code (basically: let _isElement(c_entity_node) return 1). When would they appear in the tree? We would additionally need a "resolve_entities" keyword argument for the parsers, that would be the easiest way to deal with this. If it is set, unresolvable entities will result in an error as described above. Otherwise, entity references will not be replaced. Any comments? Stefan

Re: [lxml-dev] lxml lets undeclared entities pass through silently (was: Xhtml and entities)
by Stefan Behnel May 27, 2007

May 27, 2007

Hi Eric, please reply also to the mailing list (reply all), not just to me. That way, you may also get comments by other people and the mails will be archived and others can search and read them. Eric Garin wrote: > Sorry Stefan but I've actually read this documentation (and even several times) Sorry if I sounded somewhat harsh, I do believe you. > So I did a test with something really simple : [parse XML containing an undeclared entity] > Result : parser says nothing even if &oneXXX; is not declared Not quite, it does say something, it just doesn't raise an exception. >>> from lxml import etree >>> parser = etree.XMLParser() >>> xml = etree.parse("entity.xml", parser) Ok, no exception here, so what happened? >>> print parser.error_log entity.xml:5:ERROR:PARSER:WAR_UNDECLARED_ENTITY: Entity 'oneXXX' not defined So, libxml2 did find the missing entity and reported the error to lxml. I looked into it and it seems that the parser continued parsing and returned a document containing the entity reference, saying that it was well formed. Therefore, lxml did not raise an exception. When you serialise the document after parsing, you will see that the entity reference is still in there,so this actually works. However, when you print the ".text" of the element containing the entity reference, it is not printed, so you can see that it is not passed on to the API level. Given the normal lxml behaviour of resolving entities and not supporting them at the API level at all, I would call this a bug. However, it is not obvious how to deal with this. I mean, entity references currently pass in and out rather nicely, they are just not visible. So raising an error here would likely break some existing code that does not explicitly load DTDs to resolve them but relies on lxml's current behaviour of passing them through. On the other hand, there is no easy way to support them at the API level, as they can occur anywhere in text content. I mean, how should lxml distinguish between a user passing in the entity "&entity;" and someone who just passes in the text "In XML, entities are written as &entity;", expecting that it gets properly escaped like any other text in lxml.etree? So it is better to raise an error here than to have users deal with entities. Any opinions on this? Stefan
