Parsing XML data into PostgreSQL using PHP

Hi,

It would be great helpful for me to know, how to parse the data which
in xml format (.xml) into PostgreSQL using PHP or in any other way.

Scenario: I have the data in .xml format with properly defined tag.  I
want to upload the data into postgreSQL.  Can i use PHP ? if So I want
to know the syntax / reference (URL..).  If PHP is not ideal one,
suggest me some other way to proceed.

Thanks in advance.

Awaiting for your earliest response
