​If the XML being generated has a fixed structure/schema I personally would
treat the XML as a serialization format and de-serialize and store it in a
database as one or more relationally linked tables.​ If you have to deal
with the possibility of dynamic structure I would still try to put the
fixed items into individual columns and then and then any dynamic items
could be stuffed into an hstore typed table.

My answer to your stated question is: what happened when you tried doing
that? Documentation and a bit of experimentation goes a long ways in
learning.
