[xslt] xslt error message

["Kaarle Kaila" <kaarle kaila fi>]

hi,

I cannot get an error message from libxslt. I would be very gratefull for
some advice in this!

I have this code:
------------
 res = xsltApplyStylesheet(cur,doc,pars);
 if (res == NULL) {


  xmlErrorPtr errx;
  errx = xmlGetLastError();
...................
}

--------
It works ok as long as the transformation succeeds but when an error occurs
in the transformation
then the function xsltApplyStylesheet  returns NULL
and also xmlGetLastError() returns NULL and I don't get any error message.

Is there a function liks xsltGetLastError() or how should I be abel to
display the reson of the failure??

regards
