parsing the google trends atom feed

Short and sweet : how to grab the google trends atom feed and parse out the links,
in 15 lines.

  1. $feed = simplexml_load_file('http://www.google.com/trends/hottrends/atom/hourly');
  2. $children =  $feed->children('http://www.w3.org/2005/Atom');
  3. $parts = $children->entry;
  4. foreach ($parts as $entry) {
  5.    $details = $entry->children('http://www.w3.org/2005/Atom');
  6.    $dom = new domDocument();
  7.    @$dom->loadHTML($details->content);
  8.    $anchors = $dom->getElementsByTagName('a');
  9.   foreach ($anchors as $anchor) {
  10.     $url = $anchor->getAttribute('href');
  11.     $urltext = $anchor->nodeValue;
  12.     echo 'Link: <a href="' . $url . '" title="' . $urltext . '">' . $urltext . '</a> ';
  13.   }
  14. }

Requires php with simplexml and dom xml. You could use it for a blogfarm script but that’s about all I can think of.

$dom->loadHTML((string) $details->content);

@$dom->loadHTML($details->content);

    I tried to using this script in my site but i found warning like this

    Warning: DOMDocument::loadHTML() [domdocument.loadhtml]: htmlParseEntityRef: expecting ‘;’ in Entity, line: 2 in /home/username/public_html/gtrends.php on line 8

    Whats wrong?

  4. Thank you Sir…

    I was searching on the net the whole day for a solution to parse the google hot trends.
    I tried several scripts and failed.

    Finally I got your script. Its really cool, simple and efficient, which works pretty nice.

    Thank you once again.

    Keep writing useful scripts.

  5. I made a google trends parser with C++ but it does a few extra things and runs on any Linux/Unix/BSD platform with ease. It uses wget to download and separates the keywords for you into two files a plain text and a single line file that always contains the latest keywords of the hour and it even makes pages that recognize certain words like video and episode… Check the completely automated output at:
