Fatal error: Call to a member function appendChild()

[alittee]

This is driving me up the wall what causes this to happen?

 

/*CREATING XML DOCUMENT*/
	$doc = new DOMDocument('1.0');

	//creating document format
	$doc->formatOutput = true;	

	$doc->load($patXML);

	//root node - policies
	$pols = $doc->getElementsByTagName('Policies')->item(0);

	//child node - policy
	$policy = $doc->createElement('Policy');
	$pols->appendChild($policy);

 

Just want to add another element to the XML file.

 

Thanks

Sorrry the Error I'm receiving is Fatal error: Call to a member function appendChild() on a non-object on line....

the item() call will return NULL if there is no item at that index.

$pols = $doc->getElementsByTagName('Policies')->item(0);
if($pols == NULL){
	die('No element found');
}else{
	$policy = $doc->createElement('Policy');
	$pols->appendChild($policy);
}

THANK YOU SOOOO MUCH! but how did that work??? seems like it would have just been something that tests if it was working not necessarily a fix to the problem???

 

Either way thank you a lot, I may have ended up breaking something.
