I am using xslt and I want to implement sorting on my href link.
below is the xslt part where I need to implement sorting.

Now everything is working fine, however I want to implement sorting on the href link in above xslt.
<tr>
<th scope="col" class="first sortSelected">
<div class="thPadding">
<xsl:element name="a">
<xsl:attribute name="href"></xsl:attribute>
<xsl:attribute name="class">iconDownSortArrow</xsl:attribute>
</xsl:element>Destination
</div>
</th>
<th scope="col" class="sortHover">
<div class="thPadding">
<xsl:element name="a">
<xsl:attribute name="href"></xsl:attribute>
<xsl:attribute name="class">iconSortArrowOff</xsl:attribute>
</xsl:element>Country
</div>
</th>
<th scope="col" class="sortHover">
<div class="thPadding">
<xsl:element name="a">
<xsl:attribute name="href"></xsl:attribute>
<xsl:attribute name="class">iconSortArrowOff</xsl:attribute>
</xsl:element>Region
</div>
</th>
</tr>

Please suggest!
Thanks.
Before each close tag
</xsl:apply-templates>you need to include an<xsl:sort>, e.g.The above code assumes that @href is an attribute of the destination element, but that’s just a guess, since you haven’t told us where @href appears in the input. Unless I missed something.
If you need further help please post a sample of your input XML.
On second reading, I wonder if you mean that you want to sort based on which of the three a elements is clicked on? Please clarify, and edit your question to include a sample of your input XML.
OK, based on your comment it’s clear that you want to sort based on whichever column the user clicked on last.
To expand on what Alejandro was saying, interactive behavior is outside the scope of XSLT. If you want XSLT to sort based on varying columns, you need to pass that column to the XSLT as an initial parameter. If the XSLT is running on the server, the whole page will reload when you change the sort order of the table. Do you want that?
For instant sorting you could call the XSLT within js on the client, but that’s a bit hairy. Usually for interactive sorting, people just sort directly in javascript. Here are some tutorials and implementations:
