Not sure how cURL has anything to do with XML data, but...

Two suggestions you'll probably find from different people are either [man]SimpleXML[/man] or [man]DOM[/man] (see this page in the PHP manual for more: [man]refs.xml[/man]).

EDIT: If you're not familiar with OOP programming, DOM can seem a little daunting at first. Since it's my favorite, however, I thought I'd help make it more appealing with an example. :p

Assuming you've loaded the XML into a DOMDocument object, the following code:

$attributes= $doc->getElementsByTagName('REQUEST')->item(0)->attributes;
$request = array();

foreach($attributes as $attr)
  $request[$attr->name] = $attr->value;

print_r($request);

shows that the resulting array looks like:

Array
(
    [USERNAME] => demo
    [PASSWORD] => demo
)

Nothing with the XML as such, but sending a request with XML data and waiting for an XML response seems to be easiest to handle with curl in my opinion.

Oops! I didn't read the OP's post carefully enough. In my mind, I thought the process was reversed... the initial XML request was being received from some 3rd party... not sent to. :o My mistake!

Anyway, as to sending and receiving an XML response, I usually find cURL to involve a lot of overhead (both in the sense of what the code looks like and all of the features/options cURL offers). As such, I've usually just done something like this:

$context = stream_context_create(array( 
  'http' => array( 
    'method'  => 'POST', 
    'header'  => "Content-type: application/xml\r\n",
    'content' => $xml_string_here, 
    'timeout' => 5, 
  ), 
)); 
$xml_response = file_get_contents('http://theirsite.com/path/to/api', false, $context);
