using the following xml I want to find out with XSLT which node is the next to the current node. "Next" is defined as a number-prefix of the node-title"

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:tcm="http://www.CMS.com/ContentManager/5.0">
  <xsl:output method="xml" indent="yes"/>

<xsl:key name="nextItem" match="tcm:Item"
	use="../tcm:Item[number(substring-before(current()/@Title,' '))=
	 number(substring-before(@Title,' '))+1]/@ID"/>

<xsl:template match="tcm:Item">
Current node ID: <xsl:value-of select="@ID"/>
	Next node ID: <xsl:value-of select="key('nextItem',@ID)/@ID"/>
</xsl:template>

regards,
