REST requests...XML in PHP

irf2k

I am somewhat new to the world of PHP and REST requests...
I am using php v4.4.2 on a SHARED server.
Currently, I need to know how to access the variables that are returned from this code:

$url= "http://webservices.amazon.com/onca/xml?Service=AWSECommerceService&SubscriptionId=1E3R5HVJWYX4PXS3R382&Operation=ItemLookup&ResponseGroup=Medium&AssociateTag=afterhighsc06-20&ItemId=0385504209";
$c   = curl_init($url);
curl_setopt($c, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($c);
curl_close($c);

if you go to the url shown above, you will see the code in xml...

Of course, I could just use:

$result = file_get_contents($url);

either way, I need to know, what do I do to access the variables that are returned?
Currently, I am using:

$items = $result->Items->Item;

but I know this is WRONG because I et no error and NO TEXT.

WHAT DO I NEED TO DO IN BETWEEN?

ok, so i realized i need to use DOMXML commands, but the problem is this...
my server (shared hosting) is setup as such:
DOM/XML enabled

DOM/XML API Version 20031129

libxml Version 2.6.19

HTML Support enabled

XPath Support enabled

XPointer Support enabled

Schema Support enabled

RelaxNG Support enabled

BUT...when i use this code:

$result = domxml_xmltree($newresult)

I get this error:
Fatal error: Call to undefined function domxml_xmltree() in ....
please let me know what I'm doing wrong or what other options I have...
thnx

FatalError

That's a problem with the host...hmmm...strange...it says DOM/XML is enabled, but the function is undefined...what version of PHP does the host have?

phpinfo() yields this result:
_SERVER["SERVER_SOFTWARE"] Servage.net Cluster (Enhanced Apache) (Unix) mod_ssl/2.8.15 OpenSSL/0.9.7f PHP/4.4.2

but if u need to see all the info, i have it on:
http://www.afterhighschool.ca/finances/textbooks/test.php

i did note that the configuration file was pointing to:
Configuration File (php.ini) Path /imports/php5/php.ini

would that make a difference?
thx
