In other words you want to get the line/column information of the current
position so that you can print it together with your application-specific
error.

The way to get to this information depends on the underlying XML parser
you are using (Expat or Xerces-C++). But the general approach would be
to create the parser yourself, then use this parser to parse the document
and query it for the current line/column information in case of an error.
This is fairly easy to implement with Expat and slightly more difficult
with Xerces-C++.
