simple dom xml

[prometheos]

Hi, i have an xml in the following format (ratings as root). I want to increment the 'stars' attribute.

<ratings stars="0">
   <rating>
      <experience></experience>
      <comment></comment>
   </rating>
</ratings>

 

Here's what i have to increment the stars attribute, but it's not working? ($experience is a posted variable)

$dom = new DOMDocument();							
$dom->load($forfilename);
if($experience=="Positive"){
	$val += 1;
	$dom->setAttribute('stars', $val);
}else{
	$val -= 1;
	$dom->setAttribute('stars', $val);
}
$dom->save($forfilename);

Can any1 help me :S this should work right? What am i missing?

Thanks in advance

Check if th file is loading correctly:

 

echo $dom->saveXML();

 

Use that before and after the if condition.

 

Also, are you using some special class, i dont see a 'setAttribute' method listed in the php manual for the default DOMDocument class.

Thanks for the reply, i realised that about the document class so i changed it to this and its working now! thanks

here's what i have :

$xmlDoc = new DOMDocument();
$xmlDoc->load($filename); 

if($experience=="Positive"){
	$searchNode = $xmlDoc->getElementsByTagName("ratings"); 
	$val += 1;
	$ratings = $searchNode->item(0);
	$ratings->setAttribute('stars', $val);

}
