Could someone point me toward a very simple bare bones example of a
PHP script for connecting to a server external to the one running the
PHP script and accepting the small XML file that server will return?
And maybe give me a few PHP keywords I can study for parsing that XML
file?
The XML file will contain a Session ID. So a few PHP keywords related
to initiating a PHP session using that Session ID would be really
helpful.
Thank you.

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.

Thank you Jerry. It's supposedly a well formed XML file. And just
the words "DOM classes" scares me. ;-)
But in any case you've given me some things to look into and after
that if I haven't figured it out I'll at least be able to ask a more
focused question.
Thanks again.

Ah, the DOM Classes aren't THAT bad! They are just a bit more
complicated than SimpleXML - but provide more functionality.

I completely agree with Jerry one this one. DOM is the way to go.

Not necessarily. It all depends on how the server is configured. I've
seen some which only pass it as a $_POST value in an XML form, and not
call it PHPSESSID.
It all depends on what's on the other end.
