body: <p>Having some trouble selecting some nodes in the rss feed for twitter's search</p>
  
  <p>the rss url is here</p>
  
  <pre><code>http://search.twitter.com/search.rss?q=twitfile
  </code></pre>
  
  <p>each item looks like this</p>
  
  <pre><code>&lt;item&gt;

  <p>My php is below</p>
  
  <pre><code>  foreach ($twitter_xml-&gt;channel-&gt;item as $key) {
  $screenname = $key-&gt;{"author"};
  $date = $key-&gt;{"pubDate"};
  $profimg = $key-&gt;{"google:image_link"};
  $link = $key-&gt;{"link"};
  $title = $key-&gt;{"title"};
  echo"
                          &lt;li&gt;
                          &lt;a href=$link&gt;&lt;img width=48 height=48 src=\"$profimg\"&gt;&lt;/a&gt;
                          &lt;h5&gt;&lt;a href=$link&gt;$author&lt;/a&gt;&lt;/h5&gt;
                          &lt;p class=info&gt;&lt;a href=$link&gt;$title&lt;/a&gt;&lt;/p&gt;
                          &lt;/li&gt;
  ";
  </code></pre>
  
  <p>Problem is nothing is being echoed, i mean from the rss feed, if there are 20 results, its looping 20 times, just no data</p>
