I seem to have found a solution for the problem where libxml2 wasn't
using lou_logPrint. Check the latest commit in liblouisxml
(http://code.google.com/p/liblouisxml/source/detail?r=206). I used
http://github.com/martine/LogJam/blob/master/src/tools.c#L284 as an
example on how to achieve this. However as you see from the example what
is missing is the clean up part. I do not free the context (
xmlFreeParserCtxt(ctxt);) and I do not set the old error handler
(apparently through initGenericErrorDefaultFunc(NULL);). I tried to do
this but I got a segmentation fault.
Maybe this helps for further explorations
Thanks
Christian
