Simple XML hack (See code) Need XML children $10

I will pay $10 for the simple fix --- YOU MUST JOIN THE CATEGORIES INTO A SINGLE STRING I am trying to scrape the Freelancer board listings, I can get the from the RSS feed but I am stuck getting the CATEGORIES for the projects. 1) It can be a single string 2) It can be an array -------------------------------------------------------------------------- <?php // Grab the job board listings $url = "http://www.freelancer.com/rss.xml"; $xml = simplexml_load_file($url); $items = $xml->xpath("//item"); foreach ($items as $item){ // THIS WILL NOT JOIN THE CHILDREN $categories = join( ",", $item->category); echo $item->title."<BR>"; echo $item->pubDate."<BR>"; echo $item->link."<BR>"; echo $item->description."<BR>"; } ?> ----------------------------------------------------------------------------------------
