XSL Param with XPath expressions

[V4mp1r3]

Hi !

I'm making a XSL that returns distinct values from a XML Element, but the element is dynamic, so i pass it from the server as a Parameter.

XSL:

<?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" />
 
<xsl:param name="puff" />
<Element>
    <xsl:template match="/">            
        <xsl:for-each select="//$puff[not(.=preceding::$puff)]">
            <value><xsl:value-of select="." /></value>        
        </xsl:for-each>
 
    </xsl:template>
 
</Element>
</xsl:stylesheet>

It gives me syntax error when i use the param in the xpath expressions.. any solution? Thanks in advance

Try this way:

...
<xsl:for-each select="concat('//', $puff, '[not(.=preceding::', $puff, ')]')">
