how do i grab this from the xml?

How do i grab the link href (under the published node) from this xml:

<entry>
<id>tag:search.twitter.com,2005:8927670fcdf59031552</id>
<published>2011-07-08T10:16:40Z</published>
<link type="text/html" href="http://twitter.com/username/statuses/892767c088fds031552" rel="alternate"/>
<title>dfdf</title>
<content type="html">fdf</content>

when I have this php:

 $xml = simplexml_load开发者_StackOverflow_file("http://search.twitter.com/search.atom?q=from%3Ausername&rpp=10");
        if($xml) {
                    $url = $xml->entry->link->href;
                      $status = $xml->entry->title;

Problem i see is that there's more than one link node and also there's more than one atrribute for the link node..

try this:

$xml->entry->link[0]->attributes()->href; //this is for the first href node

---

Try:

$url = $xml->entry->link[0]->href;
