[SOLVED] xmlns:xsi and xsi:schemaLocation are valid xml ?

I am using the lxml 2.0 library in Ptyhon to generate gexf.
This library returns warning when declaring both attributes containing a semicolon :
/home/pom/trunk/gexf.py:33: TagNameWarning: Tag names must not contain ':', lxml 2.0 will enforce well-formed tag names as required by the XML specification.
gexfXML.set("xmlns:xsi",self.xsi)
/home/pom/trunk/gexf.py:34: TagNameWarning: Tag names must not contain ':', lxml 2.0 will enforce well-formed tag names as required by the XML specification.
gexfXML.set("xsi:schemaLocation",self.schemaLocation)
It's not a big deal since only a warning but it claims it not correct regarding XMl specification which I don't know.

This is incredible, but I discovered that xsi:schemaLocation make the XML file invalid. You can browse the Web to find the exact reason of this issue, but it seems to be something the consortium who made the specifications have just...forgotten. Remove this line to hide this warning.

Actually I just discovered the notion of namespace in xml.
For people using lxml and python here is hte right way to write the gexf tag :
Code: Select all
xmlns="http://www.gephi.org/gexf/1.1draft"
xsi="http://www.w3.org/2001/XMLSchema-instance"
schemaLocation="http://www.gephi.org/gexf/1.1draft http://gephi.org/gexf/1.1draft.xsd"
viz="http://www.gexf.net/1.1draft/viz"
version="1.1"
gexfXML = etree.Element("{"+xmlns+"}gexf",version=version,nsmap={None:xmlns,'viz':viz,'xsi':xsi})
gexfXML.set("{xsi}schemaLocation",schemaLocation)
I am still working on a libgexf pure python. I will release it soon and post a topic in the forum.
