Newbie Question: Filtering Elements out of a Collectio

I apologise in advance if this is in a list FAQ.

I have this rather simple xml file that contains the following:

<shapeCollection>
	<shapeSet id="ID01">
		<square/>
		<rectangle/>
		<ellipse/>
	</shapeSet>
	<shapeSet id="ID02">
		<circle/>
		<square/>
		</shapeSet>
	<shapeSet id="ID03">
		<circle/>
		<ellipse/>
	</shapeSet>
	<shapeSet id="ID04">
		<circle/>
		<octagon/>
	</shapeSet>
</shapeCollection>


	Where there is an arbirary number of shapeSets. How would I generate a
collection of shape sets that didn't contain any shape set that had an
ellipse in it? I would think this is a rather simple xslt script but I admit
that I'm so new at this that the idea of it is elluding me.
