Generate XML by data from MySQL

Hey,

I searched, but I couldn’t find anything.
I have data in my MysQL database, and I want that php creats an xml file with it.
And the xml file need to look like this:

<?xml version="1.0"?>
	<myMenu>

			<myItem doubleBurner="no" outlet1="90mm"  outlet2="Regular Vent" file="images/A36.jpg" moreInfo="no" name="A36" lenght="650mm" depth="200mm" capacityM3="40-70" operatingInstructions="download" woodPebbles="-" electronicControl="no" flameVisible="yes" outputW="4100" floorCentreOutlet="320mm" gasaansluiting="3/8" " height="610mm"/>
	</myMenu>
