Complex for-each comparison problem

Hi,

i wrote days before about CDATA compare problems and now i know my problem is at another point.

xml:
-------------------------------------
<itables>
   <itable id=1 name="h">
      <i>
         <paramter>
	    <value="<![CDATA[7]]>"/>	
	    <value="<![CDATA[8]]>"/>
	 </paramter>
      </i>
   <itable id=2 name="s">
      <i>
         <paramter>
	    <value="<![CDATA[1]]>"/>	
	    <value="<![CDATA[5]]>"/>
	 </paramter>
      </i>
   </itable>
</itables>
-------------------------------------

I want to compare each itable/@id with each value:

itable id=1 with
	<![CDATA[7]]>
	<![CDATA[8]]>
	<![CDATA[1]]>
	<![CDATA[5]]>

itable id=2 with
	<![CDATA[7]]>
	<![CDATA[8]]>
	<![CDATA[1]]>
	<![CDATA[5]]>

and then i want give out the itable name where id = value.

I hope i expressed myself clearly.

Best reagrds and thanks

Sven
