Search specific text on a webpage using xpath

Question

I want to search specific text on a webpage using XPath.

<?php
$url = 'http://www.barringtonsports.com/browse/hockey_sticks/show/325/list';
$html = file_get_contents($url);        
$doc = new DOMDocument();
@$doc->loadHTML($html);     
$xpath = new DOMXPath($doc);
$found = $xpath->evaluate("//span[contains(text(),'blablabla')]");
if(!$found){
   echo "NOT FOUND";        
}
else{
    echo "found";
}
?>

it always give the output found as the text blablabla is not in the webpage. where is the problem? Is my evalute expression correct for searching specific text?

Answer 1

evaluate will not return a boolean for a XPath expression that selects a node, you have to use:

$found = $xpath->evaluate("boolean(//span[contains(text(),'blablabla')])");
