Hi Mukul

Many thanks for taking the time to covert the stylesheet to pure XSLT
1.0, it is appreciated.

Regards.

Hi Kevin,
  A pure XSLT 1.0 solution struck to me(i.e. without
extension functions), and I thought of sharing it with
you.

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

<xsl:output method="xml"  indent="yes"/>

<xsl:variable name="filea"
select="document('filea.xml')" />
<xsl:variable name="fileb"
select="document('fileb.xml')" />

<xsl:template match="/">
  <supplements>
    <!--finding supp-desc tags common to both files
-->
    <xsl:for-each select="supplements/supp">
      <xsl:variable name="desc-a" select="supp-desc"
/>
      <xsl:variable name="price-a" select="supp-price"
/>
      <xsl:for-each select="$fileb/supplements/supp">
        <xsl:if test="supp-desc = $desc-a">
          <supp>
            <supp-desc><xsl:value-of
select="supp-desc" /></supp-desc>
            <supp-price source="filea"><xsl:value-of
select="$price-a" /></supp-price>
            <supp-price source="fileb"><xsl:value-of
select="supp-price" /></supp-price>
          </supp>
        </xsl:if>
      </xsl:for-each>
    </xsl:for-each>

    <!--finding supp-desc tags existing only in
filea.xml -->
    <xsl:for-each select="supplements/supp">
      <xsl:variable name="desc-a" select="supp-desc"
/>
      <xsl:variable name="price-a" select="supp-price"
/>
      <xsl:variable name="temp">
        <xsl:for-each
select="$fileb/supplements/supp">
          <xsl:if test="supp-desc = $desc-a">
            1
          </xsl:if>
        </xsl:for-each>
      </xsl:variable>
      <xsl:if test="not(contains($temp, '1'))">
        <supp>
          <supp-desc><xsl:value-of select="$desc-a"
/></supp-desc>
          <supp-price source="filea"><xsl:value-of
select="$price-a" /></supp-price>
          <supp-price source="fileb">-</supp-price>
        </supp>
      </xsl:if>
    </xsl:for-each>

    <!--finding supp-desc tags existing only in
fileb.xml -->
    <xsl:for-each select="$fileb/supplements/supp">
      <xsl:variable name="desc-b" select="supp-desc"
/>
      <xsl:variable name="price-b" select="supp-price"
/>
      <xsl:variable name="temp">
        <xsl:for-each
select="$filea/supplements/supp">
          <xsl:if test="supp-desc = $desc-b">
            1
          </xsl:if>
        </xsl:for-each>
      </xsl:variable>
      <xsl:if test="not(contains($temp, '1'))">
        <supp>
          <supp-desc><xsl:value-of select="$desc-b"
/></supp-desc>
	  <supp-price source="filea">-</supp-price>
	  <supp-price source="fileb"><xsl:value-of
select="$price-b" /></supp-price>
	</supp>
      </xsl:if>
    </xsl:for-each>

</supplements>
</xsl:template>

</xsl:stylesheet>

Mukul
