[lxml-dev] Strange ValueError

[pythonalex at email.it]

Hello everyone. I'm Alessio Esposito and collaborate with the Institute
of Cybernetics of the CNR in Pozzuoli (NA) - Italy,

I have the latest version of lxml (lxml 2.1.4).

I need to have something like this:


...
	<octapyelement xsi:schemaLocation="http://octapycms.remuna.org/schema.xsd">
          
		<octapy:first> something </octapy:first>
		<octapy:second> something </octapy:second>
		...
		...
          
	</octapyelement>
...


And this is the python code:

...
e_octapy = SubElement(rootelement, 'octapyelement')
e_octapy.set('{%s}schemaLocation' % NS_XSI,
'http://octapycms.remuna.org/schema.xsd')
for sub_elem in struct: 
    e = SubElement( e_octapy, sub_elem )
    e.text = 'something'
...


The variable sub_elem contain strings octapy:first, octapy:second etc.

The problem is that the latest version of lxml does not accept that sub_elem
contains ':' .

This is a part of the terminal output:

Module lxml.etree, line 2342, in lxml.etree.SubElement
(src/lxml/lxml.etree.c:%u)
Module lxml.etree, line 160, in lxml.etree._makeSubElement
(src/lxml/lxml.etree.c:%u)
Module lxml.etree, line 1311, in lxml.etree._tagValidOrRaise
(src/lxml/lxml.etree.c:%u)
ValueError: Invalid tag name u'octapy:first'

The previous version of lxml (lxml 2.1) whit the same code gave no problems.

How can I fix this?

Kind regards, Alessio.
