Re: [xsl] Parameters in XPath

---

---

What I'm trying to accomplish with the Filter
parameter is to dynamically pass into the stylesheet a
XPath expression to be evaluated.
For example:

<xsl:param name="Filter" select="@rebate>9.99 and
@shippingMethod='Ground' and @cost<199.99"/>

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

Thanks.
