finding nodes

hi all,

if have a xml-document with the following structure (with nested page-nodes):

<site>
	<pages>
	
		<page id="SECTION_1">

			<page id="SUB_SECTION_1_1">

				<page id="SUB_SUB_SECTION_1_1_1">

				</page>

			</page>

			<page id="SUB_SECTION_1_2">

				....

			</page>
		</page>

		<page id="SECTION_2">

			....
		
		</page>

		


	</pages>
</site>


in my xsl-document I have the following parameter:
(later given via GET-request-params/Cocoon)

<xsl:param name="goto_page" select="SECTION_1/SUB_SECTION_1_1/SUB_SUB_SECTION_1_1_1"/>

an now I want to enter the node specified by the path given in $goto_page. this path 
has no restriction in depth.

i would prefer a solution without splitting the path if there is any? 

can anybody help me or does anybody know a howto-page or anything that could 
help me ?
thanks

cheers
jm
