dynamic selection of elements

Hi list,

I have a performance problem with xalan:evaluate, first the scenario:

<somegeneratedxml>
	<wishlist>
		<item id="length">
		<item id="weight">
		<item id="speed">
	</wishlist>
	<data>
		<item>
			<length>100</length>
			<height>100</height>
			<weight>100</weight>
			<color>red</color>
			<speed>100</speed>
		</item>
		<item>
			<length>100</length>
			<height>100</height>
			<weight>100</weight>
			<color>red</color>
			<speed>100</speed>
		</item>
		... a lot more item childs
     </datat>
</somegeneratedxml>

the wishlist items are dynamic and represent the set of data that I want to pick from each item in the data set, so I constructed for each wishlist/item a path with xalan:evaluate, which selects the elements from each data/item, but this is very slow. A better idea anyone?

Michael
