Alas, that module will not help you much with the insertion of records.
It is more about querying XML that is stored within the database. 

A basic question is whether you want to store XML in the DB or you just
have data that is in XML now and you want it loaded into a table
structure. The xml2 module will only be useful in the first case.

In either case the approach is to transform the data into a form that
PGSQL's COPY understands or into a bunch of INSERT statements (much less
performant). To that end you probably want to become familiar with XSLT
unless the data is so simple that a processing with regular tools (perl,
sed, awk) will suffice.
