[lxml-dev] Checking whether a node is a comment/element
by Geoffrey Sneddon April 10, 2023

April 10, 2023

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 Jan. 30, 2023

Jan. 30, 2023

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

Lxml test issue in Oracle Solaris
by Esha Wang Feb. 17, 2017

Feb. 17, 2017

Hello, I am representing Oracle, and currently working on upgrading pylxml in Solaris. We have encountered an issue while running test.py, where cov.xml_report() and cov.html_report() are generating a syntax error in lxml.etree.pyx. coverage.misc.NotPython: Couldn't parse '$(SOURCE_DIR)/src/lxml/lxml.etree.pyx' as Python source: 'invalid syntax' at line 44 Line 44 of lxml.etree.pyx is "cimport cython", and test.py does not seem to be recognizing it. We have checked that valid python (2.7.12) and cython (0.25.1) versions are being used. For now, we have created the following patch, which suppresses the error: --- lxml-3.6.4/test.py_orig 2017-01-11 14:03:08.523061540 +0000 +++ lxml-3.6.4/test.py 2017-01-11 14:03:27.417867156 +0000 @@ -606,14 +606,6 @@ walker = os.path.walk walker(os.path.abspath(cfg.basedir), add_file, None) - try: - cov.xml_report(modules, outfile='coverage.xml') - if cfg.coverdir: - cov.html_report(modules, directory=cfg.coverdir) - finally: - # test runs can take a while, so at least try to print something - cov.report() - # That's all if success: return 0 Additional info below: >>> print("%-20s: %s" % ('Python', sys.version_info)) Python : sys.version_info(major=2, minor=7, micro=12, releaselevel='final', serial=0) >>> print("%-20s: %s" % ('lxml.etree', etree.LXML_VERSION)) lxml.etree : (3, 6, 4, 0) >>> print("%-20s: %s" % ('libxml used', etree.LIBXML_VERSION)) libxml used : (2, 9, 4) >>> print("%-20s: %s" % ('libxml compiled', etree.LIBXML_COMPILED_VERSION)) libxml compiled : (2, 9, 4) >>> print("%-20s: %s" % ('libxslt used', etree.LIBXSLT_VERSION)) libxslt used : (1, 1, 28) >>> print("%-20s: %s" % ('libxslt compiled', etree.LIBXSLT_COMPILED_VERSION)) libxslt compiled : (1, 1, 28) Please let us know if there is additional information we can provide.

`html.make_links_absolute' Ignores `resolve_base_href' Argument
by Sam Davis Feb. 17, 2017

Feb. 17, 2017

Hi, I'm wanting to use `html.make_links_absolute' [0] with a specific `base_url', which I believe should be possible. With that in mind, I have set the `resolve_base_href' argument to `False'. However, if `<base href=$URL>' tags are present in the document, it uses $URL rather than the given`base_url'. See linked code [1] for an example. I believe this occurs as follows: - `make_links_absolute' final call is to `rewrite_links' with one argument, the `link_repl' function. [2] - `rewrite_links' has `resolve_base_href=True' as a default, so it calls `resolve_base_href'. [3] - `resolve_base_href' then finds the base `tag in the document, and apply its values to all links found in the document'. [4] I think a solution would be to pass the `resolve_base_href' parameter through when `make_links_absolute' calls `resolve_base_href'. Can anyone confirm or correct my logic? Should I report it as a bug? Thanks, Sam [0] https://github.com/lxml/lxml/blob/572e10843774a5d6300125d89bdc423d53c92971/… [1] http://pastebin.com/UFKj6VsQ [2] https://github.com/lxml/lxml/blob/572e10843774a5d6300125d89bdc423d53c92971/… [3] https://github.com/lxml/lxml/blob/572e10843774a5d6300125d89bdc423d53c92971/… [4] https://github.com/lxml/lxml/blob/572e10843774a5d6300125d89bdc423d53c92971/…

ElementTree.write() and doctype
by Steven Vereecken Jan. 22, 2017

Jan. 22, 2017

Hi, I was looking for a way to specify a doctype with the write() method of an elementtree, analogous to the "doctype" argument for etree.tostring(). There seems to be no documented way to do so, but I found an (undocumented) argument called "docstring" (instead of "doctype") that seems to work just fine. Should this be renamed to "doctype" and added to the documentation, or is there a reason why it was left out and shouldn't be used? greetings, Steven

Type attributes with E-factory
by Richard Wellum Jan. 17, 2017

Jan. 17, 2017

Hi, Sorry for the very basic question. I'm trying lxml for the first time, playing with the builder and I would like to know if it's possible to create type attributes in the top level? E.g: <domain *type='kvm' id='19'*> <name>mcontroller</name> <uuid>9b9e2237-fff5-4598-92ec-89603e4c300a</uuid> </domain> I can't figure out how to add " *type='kvm' id='19'*" to the *domain *above. Something like: controller = E.domain((type='kvm', id='19') E.name('mcontroller'), ... Thanks, ||Rich
