PHP XmlReader problem

doc_1982

I've been toying around with a simple php script that uses the xmlreader function to print out various things from an xml file, by placing different things inside the printf statements in the while loop, like so:

<?php
$xml = new XMLReader();
$xml->open("filename.xml");
while($xml->read())
{
printf($xml->name."\n");
printf($xml->depth."\n");
printf($xml->value."\n");

}
?>

However, when i use the xml->name function, to print the name of the nodes, it prints the name of the node, followed by either usually #text or #comment.
The actual xml looks like this

<product_type>Album</product_type>
<total_duration>01:10:28</total_duration>
<total_components>1</total_components>

While a sample output(with the other 2 printf statements commented out) for my code would look like this:

product_type #text product_type #text
total_duration #text total_duration #text
total_components #text total_components #text

Does anybody know how to fix this?
