Hi,
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 already had any parsing functions implemented that I can use to do the XML parsing. This is getting difficult as I was not able to get any DTD or XML Schema for the XML files generated by PostgreSQL.
I found the files xpath.c/xslt_proc.c files that contain parsing related 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 deprecated.
It would be greatly helpful if someone could guide me on this.
Thank you.
