Re: Handling Duplicate Lines in XSL

Heres a quick fix to your grouping problem...

If the XML was in the following format...

<foo>
    <bar>Cust1 443 West</bar>
    <bar>Cust1 443 West</bar>
    <bar>Cust1 443 West</bar>
    <bar>Cust1 443 East</bar>
</foo>

the following XSL will test to see if the current node is equal to any of
the preceding elements and if it is it will not include it in the resulting
node-set.  It then prints the value of each node.  So this...

<xsl:for-each select="foo/bar[not(. = preceding-sibling::bar)]">

    <xsl:value-of select="."/><br/>

</xsl:for-each>

Will produce this...

Cust1 443 West
Cust1 443 East

Best of luck,

M.
