Question

I’m receiving an XML file via API and parsing it with PHP / SimpleXML / XPath.

I need to take data from one of the fields that contains HTML and output it, however the HTML is all prefixed with a “h:” namespace.

Example XML:

<xmlfeed>
 <title>Title Here</title>
  <a:content xmlns:a="http://www.w3.org/2005/Atom" xmlns:h="http://www.w3.org/1999/xhtml">   
    <h:table xmlns:h="http://www.w3.org/1999/xhtml" width="1360" height="259" cellspacing="0" cellpadding="0" border="0">
     <h:tbody><h:tr><h:td width="35%" colspan="3"></h:td></h:tr></h:tbody>
    </h:table>
  <h:h3 xmlns:h="http://www.w3.org/1999/xhtml">Test heading here</h:h3>
  <h:a href="link.php">Link Here</h:a>
 </a:content>
</xmlfeed>

How can I parse all the HTML within a:content to remove the “h:” prefix from each element as well as the namespaces?

Thank you.

I must have glossed over this in the documentation.

It took a little while to find, but the following seems to work well:

$content = $xpath->query('a:content/h:*', $context);
foreach ($content as $piece)
{
    $piece->removeAttributeNS('http://www.w3.org/1999/xhtml', 'h');
    $html_content .= $dom->saveXML($piece);
}

Hope this helps someone else trying to solve the same issue.
