can you please tell me that one.

If you just wish to remove the empty ones, you may use a regular expression replace. See this code for an example.

$xml = "<tags>
  <tag><![CDATA[here is content]]></tag>
  <tag><![CDATA[     ]]></tag>
</tags>";
$cleanedXml = preg_replace('/<!\[CDATA\[\s*\]\]>/ims', '', $xml);

The output then would be:

<tags>
  <tag><![CDATA[here is content]]></tag>
  <tag></tag>
</tags>

Hope this helps!
