This is supposedly not possible. An XML parser (which feeds SAX) is required
to stop reporting characters when it reaches a fatal error. The parser can
continue to parse for the purpose of finding other errors but that is all it
is allowed to report [1]. That said I don't know which SAX parsers actually
continue past a fatal error. Not AElfred2.

Via SAX this information is not required to be available (though it is
sometimes in the error message). It may be possible to get the line and
column position for the error which would theoretically point to the
beginning of the Surname string (the "S" would be the first character)-- 
though, error positioning is not regulated in SAX and some parsers vary. For
example, I think Expat returns character position as a 0 based value and
MSXML as a 1 based value.

What parser are you using with SAX?
