I am working on adding a functionality to PostgreSQL. I need to parse
the XML format query plan (produced by PostgreSQL v9.3) and save it in a
simple data structure (say C structure). I was wondering if PostgreSQL

parsing. This is getting difficult as I was not able to get any DTD or XML
Schema for the XML files generated by PostgreSQL.

code, but none of the functions are being called for any xml related query
I issue to the database and some of the functions in those files mention as

   It would be greatly helpful if someone could guide me on this.

   Thank you.
