Write to XML file using the DOM

[rhyspaterson]

Hey guys,

 

I am reading in data from an XML file which looks like such:

 

<?xml version="1.0" encoding="iso-8859-1"?>
<building>
<floor level="ground">
	<printer>
		<name>PRINTER_1</name>
		<updated>2008-09-11T13:22:00+10:00</updated>
	</printer>
	<printer>
		<name>PRINTER_2</name>
		<updated>2008-09-11T13:22:01+10:00</updated>
	</printer>
</floor>
</building>

 

- and the PHP code:

 

<?
$printers = $document->getElementsByTagName( "printer" );
foreach( $printers as $printer )
{
$names = $printer->getElementsByTagName( "name" );
$name = $names->item(0)->nodeValue;

$updateds = $printer->getElementsByTagName( "updated" );
$updated = $updateds->item(0)->nodeValue;

echo "Printer name is $name and was updated at $updated";
}
?>

 

Now everything is fine and dandy. However, i can't for the life of me figure out how to overwrite one of the elements. I know how to create and append, but not overwrite..! I would like to be able to search for a printer element, such as PRINTER_1 and overwrite the data in it's specific <updated></updated> tags (using the DOM if possible).

 

Any suggestions?

 

Cheers,

Rhys
