Re: [xsl] Building Dynamic Urls

[George Cristian Bina <george@xxxxxxx>]

Hi Adam,

You need to move the logic inside the variable, something like below:

<xsl:variable name="newURL">
    <xsl:value-of select="$url"/>
    <xsl:if test="child::area">
        <xsl:text>?area=</xsl:text>
        <xsl:value-of select="area"/>
    </xsl:if>
    <xsl:if test="child::action">
        <xsl:text>?action=</xsl:text>
        <xsl:value-of select="action"/>
    </xsl:if>
    <xsl:if test="child::page">
        <xsl:text>?page=</xsl:text>
        <xsl:value-of select="page"/>
    </xsl:if>
</xsl:variable>
<xsl:value-of select="$newURL"/>

with
<xsl:param name="url" select="'http://www.example.com/test'"/>
and
<area>1</area>
<action>2</action>
<page>3</page>
in the source will give you
http://www.example.com/test?area=1?action=2?page=3

Best Regards,
George
