Re: [xml] Fwd: continued problem with Python, libxml2 and entities

Mike,

You should tell libxml2 to resolve entities before doing any XSLT
processing. In your test.py, use

sourcedoc = libxml2.readFile( 'test.xml', None, libxml2.XML_PARSE_NOENT
)

If you look at pyxsltproc.py you will see that it does the same trick
with a global setting ( libxml2.substituteEntitiesDefault(1) ) but I
believe this way of doing is deprecated.
