That tells me neither what you got as output, nor what exactly you expected that you did not get. In case what you want is the complete serialisation of the "body" element, then serialise the body element. Stefan

[lxml-dev] Can't load the whole context
by David Shieh 07 Dec '09

Hi everyone, I've a problem by using lxml to parse my html file. I opened a html file, then use lxml.html.fromstring to parse it, but when I use xpath find an element and print it, it can't show the whole context. Here's the code for my oprations. from lxml.html import fromstring, tostring def test(): html = open('/home/icefox/qingbao/ sina.htm') tree = fromstring("".join(html.readlines())) text = tree.xpath('//body') file = open('test.html', 'wb') print len(text) for i, t in enumerate(text): file.write(tostring(t)) print str(i) + "---" + tostring(t)[:50] file.close() -- ---------------------------------------------- Attitude determines everything ! ----------------------------------------------

[lxml-dev] Critical crashes on Windows under high load
by Martin Aspeli 04 Dec '09

04 Dec '09

Hi folks, We have an incredibly frustrating, show-stopping problem using lxml (under Deliverance, in front of a repoze.zope2 pipeline serving up a Plone site) on Windows. Under high load, the Python process crashes. There is no traceback in the log, so I can't identify where it actually happens, but we get a Windows error dialogue saying python.exe (or pythonservice.exe if running as a Windows service) has crashed in etree.pyd (at some binary address, no line numbers or function references). The Deliverance (0.3/trunk) rules use fairly complex xpath expressions. We're trying to simplify these, but there's nothing obviously wrong, and in any case it shouldn't crash. We've tried to run both multi-threaded and single-threaded 'paster' processes: the problem happens with both. I did read somewhere that it's possible to build a single-threaded lxml egg (?), but I haven't found one. We would be incredibly grateful for any help with (a) debugging and (b) resolving this. At present, we're having to fight a lot of nervousness regarding the production-worthiness of our Deliverance/lxml based solution, which is rather unfortunate. :-( Cheers, Martin

[lxml-dev] Windows 7 64-bit
by Taylor, Martin 04 Dec '09

04 Dec '09

I'm looking for an lxml Windows binary installer for Windows 7 64-bit. On http://pypi.python.org/pypi/lxml/2.2.4 I see lxml-2.2.4.win-amd64-py2.6.exe. Is this specifically, and only, for AMD 64-bit processors or will it install and run on all 64-bit Windows platforms, including Windows 7 on Intel hardware? Thanks, Martin Taylor

Not yet. I should be getting my new Win 7 64-bit system later today. I've just be searching online for the various packages I'll need to install on this new system to prepare it for use as a test platform. If I don't get any replies to the contrary I will try it later today.
