These are pretty broad questions, so it's almost impossible to answer
them exactly.
Some hints - for fetching the page, the simplest way is to just fetch
the URL using the file functions. However, your server would have to be
configured to allow this (allow_url_fopen set to ON). Also, while this
is a simple interface, it is pretty much limited to opening a file for
read only - no cookies, etc.
A more versatile (but a bit more complicated) way is to fetch the url
with the curl functions. Not hard once you've done it a couple of
times, but there are a number of options.
Once you have the file, if it's a well-formed XML file you can probably
use the SimpleXML functions to process it. Again, this is somewhat
limited, but relatively easy to use. Another way which is more
versatile (and handles non-well-formed documents better) is the DOM
classes.
For handling the session - impossible to tell from what you're asking.
It depends a lot on whether the session id is passed in the file or the
URL (and you have to pass it back) or in a cookie (in which case you
must use the cURL function). But if you're only fetching one file, you
shouldn't have to worry about a session id - it's a single request.
Any more detail would be pure conjecture, and would very probably steer
you along the wrong path.
