[xsl] looping through Elements stored in a variable..

["Laura Jenkins" <xsl_list@xxxxxxxxxxx>]

Hello people,
i have the following xsl structure

<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
 <xsl:template match="/">
  <xsl:variable name="univ-var">
   <University-List>
    <University id = "1"> University1</University>
    <University id = "2"> University2</University>
    <University id = "3"> University3</University>
    <University id = "4"> University4</University>
   </University-List >
  </xsl:variable>
<!-- i want to iterate through this variable without usiing the extension
nodeset..-->
<!-- something along the lines of .. -->
  <xsl:for-each select="$place-var/placements/placement">
  <xsl:value-of select="."/>
  </xsl:for-each>
 </xsl:template>
</xsl:stylesheet>

What i was doing obviousl;y does not work because it needs to be a nodeset.
Can any one tell me how to do this without using the extension : nodeset.
Its is  MANDATORY that I  DO NOT USE the extension nodeset.
Thanks
