Mad multiple select, and I'm getting it all wrong!!!

Hello again everyone (sorry, I'll figure this stuff out in the end),

I'm writing a select for an apply-templates command, but I'm getting it all
mixed up. This is what I've written:

	<xsl:apply-templates
		select="HoldingInformation2Response/Items/Item[class_code =
			RetrieveClassInfoRSResponse/Items/Item/ClassCode[../DisplayOnInternetSite
= 'Y']]" />

And what I want to do, is select all Item nodes from
HoldingInformation2Response/Items where it's class_code is equal to all
ClassCode nodes from RetrieveClassInfoRSResponse/Items/Item where
DisplayOnInternetSite = 'Y'

Here are the nodes in a visual sense:

<ROOT>
<HoldingInformation2Response>
	<Items>
		<Item>
			<Holding/>
			<class_code>OMN</class_code>
			<Available>
		</Item>
		<Item>
			<Holding/>
			<class_code>DRP</class_code>
			<Available>
		</Item>
	</Items>
</HoldingInformation2Response>
<RetrieveClassInfoRSResponse>
	<Items>
		<Item>
			<ClassCode>OMN</ClassCode>
			<DisplayOnInternetSite>N</DisplayOnInternetSite>
		</Item>
	</Items>
	<Items>
		<Item>
			<ClassCode>DRP</ClassCode>
			<DisplayOnInternetSite>Y</DisplayOnInternetSite>
		</Item>
	</Items>
</RetrieveClassInfoRSResponse>
</ROOT>

This looks like it should work, but it doesn't do anything. I have a
template matching Item, and I was using this to test what was being returned
<xsl:value-of select="." />, but this wasn't doing anything.

Any help would be great.

Daniel.
