XML to Postgre conversion

Hello:

I am trying to figure out how to import xml documents
into a postgres database.  I am running PostgreSql
7.1.3 on Red Hat 7.2 at the moment.  I have several
dynamic xml documents that I want imported into the
database on a regular basis(through cron entries).
From my research so far, I know that there is
middleware available to perform this, but am having
some difficulty in finding the actual applications.  I
am trying to stay with open source applications, if
possible.  Can anyone give me any suggestions or
resources to pull from?

Thanks,

N. Hill
