Re: Parameters in XPath

<xsl:param name="Filter" select="@rebate>0"/>


so Filter is the boolean value true or false depending on the value of
the rebate attribute at this point.


<xsl:apply-templates
select="/Cat[@CatId=$Cat]/Prod[$Filter]"/>

If Filter is true it will have no effect but if Filter is the boolean
value false then this selct will not slect anything.

either way Filter is a constant value not depending on the path so this
is the same as


<xsl:if test="$Filter">
<xsl:apply-templates
select="/Cat[@CatId=$Cat]/Prod"/>
</xsl:if>
