RE: Building Dynamic Urls

Put the conditional inside the expression that initializes the variable:

<xsl:variable name="x">
  <xsl:value-of select="$url"/>
  <xsl:if test="child::area">?<xsl:value-of select="child::area"/></xsl:if>
  <xsl:if test="child::action">&amp;<xsl:value-of
select="child::action"/></xsl:if>
</xsl:variable>
