SimpleXML and Google Calendar

[Relics]

Hello all,

I'm very new to SimpleXML and I'm learning how to do parsing XML data. I've got a code bit that I'm trying to use to pull Google Calendar data and display it on a site. I don't need anything more than something to pull the data and display it. Below is the code that I'm using:

<?php
    $userid = 'username%40googlemail.com';
    $magicCookie = 'cookie';
    
    // build feed URL
    $feedURL = "http://www.google.com/calendar/feeds/USERNAMEREMOVED/public/basic";
    
    // read feed into SimpleXML object
    $sxml = simplexml_load_file($feedURL);
    
    // get number of events
    $counts = $sxml->children('http://a9.com/-/spec/opensearchrss/1.0/');
    $total = $counts->totalResults; 
    ?>
    <h1><?php echo $sxml->title; ?></h1>
    <?php echo $total; ?> event(s) found.
    <p/>
    <ol>
    <?php    
    // iterate over entries in category
    // print each entry's details
    foreach ($sxml->entry as $entry) {
      $title = stripslashes($entry->title);
      $summary = stripslashes($entry->summary);
      $link = stripslashes($entry->id);
      
      echo "<li>\n";
      echo "<h2>$title</h2>\n";
      echo "$summary <br/>\n";
      echo "$link <br/>\n";
      echo "</li>\n";
    }
    ?>

What I need is to display the link back to the Google Calendar event when clicked. The problem is I don't know how to tell the SimpleXML to use the link in XML data tagged: <link rel="alternate" .....>. There is also a <link rel="self"....> in the code, so adding "$link = stripslashes($entry->link); doesn't work. If anyone can tell me the code I need to use, I would appreciate it. Thanks

nest this within the foreach statement that you have already....

foreach ($entry->link as $link){
if($link['rel']=='alternate'){
echo "<h2><a href='" .$link['href'] . "'>" . $entry->title . "</a></h2>";
}
}
