Re: [xml] Return type of the xpath query during the compilation of xpath

[Umesh Chandak <umeshc gslab com>]

Hi Daniel,

xmlXPathCompExprPtr->steps[xmlXPathCompExprPtr->last -1]->op .
last -1 because libxml always sort the results.

will the above thing works for finding the last xpath operation.

Also will the approach of last operation to determine the  return type 
of query will work except for variables ?

Thanks.
Regards,
Umesh
