Wow, I think you have tried to apply a good old procedural language to the wonderfully functional XSLT programming language.

Try something like this instead:

Code:

<xsl:for-each select="/data/sector">
  <xsl:variable name="sector" select="."/>

  <xsl:for-each select="/data/subSector">
    <xsl:variable name="subSector" select="."/>

    <xsl:variable name="item" select="/data/item[@sector = $sector/@id and @subSector = $subSector/@id]"/>

    Sector: <xsl:value-of select="$sector/@id">
    Sub Sector: <xsl:value-of select="$subSector/@id">
    Item ID: <xsl:value-of select="$item/@id">
    Item Text: <xsl:value-of select="$item/text()">

  </xsl:for-each>

</xsl:for-each>
