[lxml-dev] pretty-printing
by Albert Brandl Feb. 24, 2007

Feb. 24, 2007

Hi! I've posted a question about pretty-printing some time ago. Now I finally found the time to construct an example. The problem occurs with the following code: nsmap = dict (foo="http://foo.org", bar = "http://bar.org") e = Element("{http://foo.org}somefoo", nsmap = nsmap) s = Element("{http://bar.org}somebar", nsmap = nsmap) e.append(s1) et = ElementTree(e) et.write("foo.xml", pretty_print = True) This code creates the following XML file: <foo:somefoo xmlns:foo="http://foo.org" … [View More]

[lxml-dev] [objectify] __MATCH_PATH_SEGMENT regex modification suggestion
by Holger Joukl Jan. 2, 2007

Jan. 2, 2007

Hi, I suggest to loosen the __MATCH_PATH_SEGMENT regex a little to care for more possible element names, which are sometimes outside of my control. Currently ObjectPath chokes on paths like 'root.a-x.a-y'. While such names are often inconvenient at best I found that python itself is quite non-restrictive wrt attibute names: python2.4 Python 2.4.3 (#2, Nov 20 2006, 16:26:48) [GCC 2.95.2 19991024 (release)] on sunos5 Type "help", "copyright", "credits" or "license" for more information. >… [View More]

[lxml-dev] lxml on OS X compile problems

Hi All, My first question - anyone successfully build lxml on OS X 10.3.9? And next, have they encoutnered the following error - specifics- OS X 10.3.9 gcc 3.3 python 2.4.4 lxml 1.1.2 libxml2 config line - ./configure \ --with-python=/Library/Frameworks/Python.framework/Versions/2.4/ libxslt config line- ./configure \ --with-python=/Library/Frameworks/Python.framework/Versions/2.4/ \ --prefix=/usr/local \ --with-libxml-prefix=/usr/local \ --with-libxml-include-prefix=/usr/local/include \… [View More] --with-libxml-libs-prefix=/usr/local/lib Results- xsltproc was compiled against libxml 20611, libxslt 10109 and libexslt 807 libxslt 10117 was compiled against libxml 20626 libexslt 807 was compiled against libxml 20611 I'm a little worried that the xsltproc wasn't combiled against the same libraries- but I'm not sure how to resolve this. I've played with installing various versions of libxslt and libxml and they seem to be installing- though all the libxml2 headers may not be installing properly. The present error occurs since I've copied the missing headers xmlstring.hand xlmsave.h to /usr/include/<etc>.

[lxml-dev] relax ng bug: validation twice doesn't give same answer
by Martijn Faassen Dec. 21, 2006

Dec. 21, 2006

Hi there, We just ran into the following problem with lxml's RelaxNG validation. Validating with the same RelaxNG schema gives the right result (invalid). Validating again however gives valid! This script is a minimal test case that demonstrates the problem. Tested with lxml 1.1.2 and libxml2 2.6.24 and also 2.6.26 on another machine. From an earlier thread last year it's possible that this is a libxml2 bug: http://codespeak.net/pipermail/lxml-dev/2005-September/000423.html This was … [View More]

[lxml-dev] Processing instruction doubt
by Steve Howe Dec. 20, 2006

Dec. 20, 2006

Hello all, This should be rather a stupid question, but supposing I have an ElementTree instance, and I want to add a processing instruction to it - in my case, a xml-stylesheet PI - how do I add that PI in the correct location of the tree (i.e. before the root) without serializing ? <?xml-stylesheet type="text/xsl" href="stylesheet.xsl"> <data> ... </data> Before someone answers "add the PI into the XSLT before serializing it", the ElementTree is received by a … [View More]

[lxml-dev] lxml documentation volunteers?
by Martijn Faassen Dec. 19, 2006

Dec. 19, 2006

Hi there, I think it's time to give the lxml documentation a reworking, in particular our API documentation. It must become more clear for users what is in the API; I find myself having to look at the code or do a dir() far too often to find whether a feature is supported. What I would wish for is API documentation similar to the module documentation on python.org. Something close to that would be familiar for users so they can get started with lxml quickly. I hope we can also continue … [View More]

[lxml-dev] About lxml status
by David Soulayrol Dec. 14, 2006

Dec. 14, 2006

Hello, I am currently using 4Suite-XML for a project on my own, which makes use of DOM, XSLT and XPath. I've always looked around if I could find other libraries to replace 4Suite eventually, and I (re-) discovered libxml today, and found a link to lxml from there. What I'd like to know is (before I dive deeply in documentation) how you would compare the XML support between 4Suite and lxml. Would you say lxml is ready for common DOM manipulations, XSLT transformations and … [View More]

I've adapted the code responsible for building the element tree to use SubElement instead of append, so that "pretty_print = True" does what I want. A minor problem remains, but I have a workaround for this. If you try to write the document to a file without … [View More]
