Re: Processing an element only if there are no better options

Use:

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
  <xsl:output omit-xml-declaration="yes"/>
  <xsl:template match="ProductGroup">
    <xsl:for-each select="Product">
      <xsl:sort select="substring-after(@Type, 'Type')"
                data-type="number"/>
      <xsl:if test="position() = 1">
        <xsl:copy-of select="."/>
      </xsl:if>
    </xsl:for-each>
  </xsl:template>
</xsl:stylesheet>

When the above transformation is applied on this source.xml:

<ProductGroup>
  <Product Type="Type3">[...]</Product>
  <Product Type="Type1">[...]</Product>
  <Product Type="Type2">[...]</Product>
</ProductGroup>

the wanted result is produced:

<Product Type="Type1">[...]</Product>
