Question

Source HTML

  <div class="number value">14,818</div>
              <div class="number delta-negative">
                     -10.19%</div>
    <div class="number value">58,016</div>
              <div class="number delta-positive">          
                    +44.38%</div>
     <div class="number value">119,561</div>
              <div class="number delta-negative">           
                    -11232</div>

Code

$doc = new DomDocument(); 
$doc->loadHTMLFile('http://example.com/source.html/');
$xpath = new DomXpath($doc);  
$query = '//div[@class="number value"]//'; 
$nodes = $xpath->query($query);  
$urls = array();  
foreach ($nodes as $node) { 
$href = trim($node->nodeValue);
$urls[] = $href;}
$datap = implode(',', $urls); 
echo $datap;

I want extract values 14,818, 58,016 and 119,561 but above code doesnt work…why?

Answer 1

Your query is for class="number_value" while your HTML says class="number value".

Change one of them (probably the HTML) to reflect this. (Question edited to correct error.)

Edit:

Running your query results in an invalid query error. Looking at your query, it’s obvious why — you have two trailing slashes. These are invalid without anything following them.

Try this:

$query = '//div[@class="number value"]';
