Thanks Dieter,
But I still cant get it to work. I've changed my get_attributes.py script
to this:
if not attobject:
return ''
version = attobject.get_viewable()
nodes = version.content.documentElement.getElementsByTagName(attname) if
not nodes:
return ''
nodeValue = nodes[0].childNodes[0].nodeValue
if not nodeValue:
return "none"
return nodeValue
and my zpt is like this:
<span id="section_subheader" tal:define="isadditional
python:here.get_uclattribute(attobject, 'ucl_additional_name')"
tal:condition="python: isadditional !='none'" tal:attributes="id
python:here.get_uclattribute(attobject,
'ucl_additional_name_color')"><span
tal:content="python:here.get_uclattribute(attobject,
'ucl_additional_name') or nothing" tal:omit-tag="">Website
Subheader</span></span>
But I get the following error:
Error Type: IndexError
error Value: list index is out of range
and the traceback says "Module None, line 7 in get_attributes" is the cause.
Hope you can help.
