Re: [xsl] XPath question concerning distinct-values()

[Mukul Gandhi <gandhi.mukul@xxxxxxxxx>]

Hi Thorsten,
    Here are few more 2.0 approaches (hopefully, would meet your
requirement) to solve this problem:

1)

  <xsl:template match="/">
	<xsl:variable name="unique-order-nums"
select="distinct-values(pricelist/item/order-number)"/>
	<xsl:variable name="docRoot" select="/"/>
	<xsl:for-each select="$unique-order-nums">
	    <xsl:value-of select="current()"/><xsl:text>
</xsl:text><xsl:value-of select="$docRoot/pricelist/item[order-number
= current()][1]/price"/><xsl:text>&#xA;</xsl:text>
	</xsl:for-each>
   </xsl:template>


2)

   <xsl:key name="item-key" match="item" use="order-number"/>
	
   <xsl:template match="/">
	 <xsl:variable name="unique-order-nums"
select="distinct-values(pricelist/item/order-number)"/>
	 <xsl:variable name="docRoot" select="/"/>
	 <xsl:for-each select="$unique-order-nums">
	      <xsl:value-of select="current()"/><xsl:text>
</xsl:text><xsl:value-of select="key('item-key', current(),
$docRoot)[1]/price"/><xsl:text>&#xA;</xsl:text>
	 </xsl:for-each>
    </xsl:template>
