Makes much more sense. I actually did something like this not too long ago. So here’s how I did it…

I took the current xml file, and looped through it. I had my variables set for the old title, and the newly updated title so I knew which one to replace. I looped through the xml file and copied everything into a new xml, until I got to the outdated block. I then replaced it with the new information I wanted and continued my loop until the end. Once finished, I saved it overwriting the old xml file. And that’s it!

I modified my large piece of code to give you a smaller one that you should be able to use with little or no modifications. Let me know if you have any questions.

Code:

formatOutput = true;//why not?
	$library = $doc->appendChild($doc->createElement(“pricing”));//creates 
	foreach($xml->package as $package) {//loops through the xml file
	  $b = $doc->createElement( “package” );//creates 
		if ($package->title == $oldtitle && $package->price == $oldprice && $package->description == $olddesc){//if we are at the outdated package, update information

			$name = $doc->createElement( “title” );//creates element <br />
			$name->appendChild($doc->createTextNode( $newtitle ));//adds $newtitle value inside the <br />
			$b->appendChild( $name );//closes element 

			$price = $doc->createElement( “price” );

			$price->appendChild($doc->createTextNode( $newprice ));

			$b->appendChild( $price );

			$desc = $doc->createElement( “description” );

			$desc->appendChild($doc->createTextNode( $newdesc ));

			$b->appendChild( $desc );

		} else {//not at the package we want to update so simply copy over to our new xml

			$name = $doc->createElement( “title” );

			$name->appendChild($doc->createTextNode( $package->title ));

			$b->appendChild( $name );

			$price = $doc->createElement( “price” );

			$price->appendChild($doc->createTextNode( $package->price ));

			$b->appendChild( $price );

			$desc = $doc->createElement( “description” );

			$desc->appendChild($doc->createTextNode( $package->description ));

			$b->appendChild( $desc );

		}
	  $library->appendChild( $b );//
	 }
   $doc->save($xmlFile);//save our new xml in place of the old one.  overwrites automatically.
}

updateXML(‘Package 1′,’$750′,’This is a description for Package 1.’,’a’,’a’,’a’);//will change package 1 to a for everything. example only
?>
