  I did not complain, I asked for informations. And I still don't have
them, I don't know what version of the libs you're using

  it could very well being linkage problems too !

  So it's probably somewhere else and that could be version or linking problems
    what are the versions you used ? 
    did you used xml2-config ? and xslt-config ? for the compile and
linking flags.

  the xmlDocPtr that you get MUST be similar. making a separate example
calling xmlParseFile oinstead of parsing the memory could help convince
you where the problem is.

  It would have forced you to separate the linking process and make sure
that what you had was pristine, too bad you don't consider my advice useful,

  libxml ??? It should be libxml2 !!!

  Discarding my suggestion is not the best way to make progresses...
