Ah, thanks a lot! So changing 

 parseString(node, "A test") to parseString(node._o, "A test")

does it. So it works, but it looks ugly. If i read your code right
that seems to be the reason for your wrappers in Is there
no way to do the unwrapping on the C side?

No, more like this: assume a module that provides functions that want
to return XML data (as a silly example: with a function
weatherAsXml('New Haven') ). It would be very convenient if the function
could return an libxl2 document object so that the return value could
be processed with functions from libxml2/libxslt. I consider this as
an essential functionallity for the interplay of modules creating or
modifying XML data. BTW, i'm _not_ really a Python programmer so maybe
i miss something rather obvious. I just had a look at and wondered
whether an API as difined in this doc is planned for libxml2.

 Thanks again
