SimpleXML to return a few items at a time

[eluser]ModernM[/eluser]
I am using simple XML to grab the data from a cURL response in XML. Now I can get everything back using this

Code:

<?php $Items = new SimpleXMLElement($res);?>
    
    
      <div class="row-fluid">
        <div class="span10">
         <ul class="thumbnails">
          &lt;?php foreach ($Items->SearchResults->Items->Item as $ProductID){
   echo '<li class="span3">
             <div class="thumbnail"> <img src="'.$ProductID-&gt;ThumbPicLink.'" alt="'.$ProductID-&gt;PrName.'">
      <h5>'.$ProductID->PrName.'</h5>
      <p>Short Description</p>
      <h6>Item Number:'.$ProductID->ProductID.'</h6>
            </div>
          </li>';
    }?&gt;
        </ul>
        </div>

How do I express this so it returns 10 items at a time, what I am trying to do is paginate the data instead of returning 10000 items at once.

Thanks
