getting content value from meta tag

Question

Considering the following code:

<div class="item">
  <meta content="2013-06-28" itemprop="date">
</div>
<div class="item">
  <meta content="2013-06-27" itemprop="date">
</div>
<div class="item">
  <meta content="2013-06-25" itemprop="date">
</div>
...

Using php and DOM/xPath, how would I extract the date values?

`$itemprops = $xpath->query("//@itemprop"); foreach ($itemprops as $itemprop) { $name = $itemprop->nodeValue; $value = $itemprop->nodeValue; }` // $name is correct but $value is empty. Also tried getting value through parentNode, getAttribute but just cant get it right. — rdvn, Jun 28 '13 at 16:52

If you just want the dates, this xpath will return them all:

//meta[@itemprop = "date"]/@content

This should help get you started:

<?php
$html = <<< ENDL
<div class="item">
  <meta content="2013-06-28" itemprop="date">
</div>
<div class="item">
  <meta content="2013-06-27" itemprop="date">
</div>
<div class="item">
  <meta content="2013-06-25" itemprop="date">
</div>  
ENDL;

$doc = new DomDocument();
$doc->loadHTML($html);
$xpath = new DOMXpath($doc);

$metas = $xpath->query("*/div[@class='item']/meta");
if(count($metas)) {
  foreach($metas as $key => $element) {
      echo "[{$element->nodeName}]";
      foreach($element->attributes as $attrName => $attrValue) {
          echo "$attrName = $attrValue->nodeValue<br>";
      }
  }
} else {
  echo "No metas found!";
}
?>

Will result in:

[meta]content = 2013-06-28
itemprop = date
[meta]content = 2013-06-27
itemprop = date
[meta]content = 2013-06-25
itemprop = date
