Processing an XML output

[Amrit Hallan <amrit@touchtelindia.net>]

I'm working on the website of a travel insurance agent who represents 
many companies. A few companies want him to use XML processing. They 
want him to submit forms in XML format. Using JavaScript/PHP I'm able to 
do that, but when the form is submitted, it generates an XML response in 
the form:

  <?xml version="1.0" ?>
- <purchaseresponse haserror="1" phc="b2tc609z1nm91">
  <redirect>twelcome</redirect>
etc.......
  </purchaseresponse>

Since the dynamically generated response originates from a remote file 
(residing on the parent company's server), how can I use this data, and 
even process it, store it, or present it to the person who has submitted 
the form?

Thanks in advance for your timely help.
