从PHP中提取XML

<toplevel>
 <CompleteSuggestion>
  <suggestion data="shook ones part 2"/>
 </CompleteSuggestion>
 <CompleteSuggestion>
  <suggestion data="shook me all night long"/>
 </CompleteSuggestion>
 <CompleteSuggestion>
  <suggestion data="shook ones instrumental"/>
 </CompleteSuggestion>
 <CompleteSuggestion>
  <suggestion data="shook me all night long lyrics"/>
 </CompleteSuggestion>
</toplevel>

I want to extract "shook ones part 2" from this XML output. I have gone through every solution, but I'm unable to do this. I tried this:

<?php
$url = 'http://suggestqueries.google.com/complete/search?output=toolbar&hl=en&q=shook&ds=yt';
$exact = simplexml_load_file($url);
echo $exact->CompleteSuggestion[0]->suggestion;
?>

    shook ones part 2 is value of an attribute data of suggestion. So you should get all attributes of a suggestion with function attributes() and select data:

    $exact = simplexml_load_file('$url');
    echo $exact->CompleteSuggestion[0]->suggestion->attributes()->data;
