Well, you need to parse the COBOL. This means you need a language that's
reasonably good at regular expression handling. Perl and Python are
common choices; XSLT 2.0 has good capabilities in this area, but XSLT
1.0 and XQuery 1.0 aren't really suitable. I've no idea what's available
on IBM mainframes.

Many XQuery processors that run on the mainframe are likely to be Java
programs. Java does offer cross-language support, but the question of
how to call Java from COBOL on an IBM mainframe is just a little bit
off-centre for this list!
