Ah, now that is a good question! I was thinking that you might be
able to use the "recursive='true'" attribute, but I tested it and it
doesn't work. I'm not sure if there is another clever way to do it.
So off hand, the only thing I can think of is to either recursively
render until the output doesn't change (really nasty for performance)
or do a pre-render of the stuff from the database. See if this code
might help:
from genshi import XML
from genshi.template import MarkupTemplate
def get_url():
return '/widget'
def PreRender(xml):
# wrap in html tags to make genshi happy
tmpl = """<html xmlns:py="http://genshi.edgewall.org/";
xmlns:xi="http://www.w3.org/2001/XInclude";
py:strip=""
>
%s
</html>
""" % (xml)
return MarkupTemplate(tmpl).generate(get_url=get_url)
db_string = '<a href="${get_url()}">Widget</a>'
strTemplate = """
<html xmlns:py="http://genshi.edgewall.org/";
xmlns:xi="http://www.w3.org/2001/XInclude";
>
<span py:replace="PreRender(db_string)"/>
</html>
"""
tmpl = MarkupTemplate(strTemplate)
stream = tmpl.generate(db_string=db_string, PreRender=PreRender)
output = stream.render('xhtml')
print output
