Lxml test issue in Oracle Solaris
by Esha Wang 17 Feb '17

17 Feb '17

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 17 Feb '17

17 Feb '17

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/…

Re: [lxml] Why can't I import etree any more? It turns out I can!

It turns out that lxml does work with Python 3.5! In response to a question I had posted on StackOverflow, a commenter asked if I had actually tested this by running a Python script, or if I was merely relying on PyCharm's statement that it didn't know what etree is. I realized that I was relying on PyCharm, and should try actually using it. I tried this script: from lxml import etree if __name__=='__main__': print ("This is a print statement.") try: x = etree.fromstring("This is not XML") except Exception as ex: print (str(ex)) The output of this was: C:\Python35\python.exe C:/Misc/lxmltest.py This is a print statement. Start tag expected, '<' not found, line 1, column 1 (<string>, line 1) Process finished with exit code 0 I was expecting an unresolved reference error. Instead, the error message shows that etree.fromstring() was successfully called.

I have found several instances of people asking this question but none of anyone answering it. In 32-bit Python 3.2, using lxml v3.2.3, I can import the etree class using this: from lxml import etree But in 64-bit Python 3.5, using the latest version of lxml acquired using "pip install lxml", the above statement fails because etree is an unknown reference. What happened? What do I have to do to use lxml's etree class now? Is there something else I need to do to install lxml for my Python 3.5 installation? I am running 64-bit Windows 7 SP 1.

Could somebody who has actually succeeded in using lxml with Python 3.5 on a Windows 7 box please tell me how they did it?

I have used lxml in a 32-bit version of Python 32. It is quite likely that I will need to port that code to run in 64-bit Python 35 on a Windows 7 SP1 box. Every time I try to use lxml in Python 3.5 via "from lxml import etree", PyCharm complains that etree is an undefined reference. The last time I tried, I changed that line to "import lxml", and then in one of my functions I typed "lxml.", allowing PyCharm's IntelliSense to tell me what symbols were available. The only available symbol was "get_includes". Am I trying to do the impossible? Has anyone actually succeeded in using lxml in Python 3.5 on a Windows box? If so, could you please tell me how you installed it? A working sample would be wonderful. Is it possible to get the source code from a tar.gz file and build it for myself? What would I need to do that?

I could be wrong but I think you still can't install lxml on Windows using pip. At least it never works for me. I always get the builds from Chris Gohlke's page: http://www.lfd.uci.edu/~gohlke/pythonlibs/#lxml pip still won't let you install files so you can do this with easy_install or use a download cache and tell pip not to use the index.
