XSLT <sort> Element
The XSLT <xsl:sort> element allows you to sort the output of the <xsl:for-each> element.
<xsl:sort> Example
Here, we use <xsl:for-each> to loop through each "tutorial" element, and <xsl:sort> to sort by the "name" node. We then use the <xsl:value-of> to extract data from the "name" node.
<?xml version="1.0" standalone="no"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<xsl:apply-templates/>
</xsl:template>
<xsl:template match="tutorials">
<xsl:for-each select="tutorial">
<xsl:sort select="name"/>
<xsl:value-of select="name"/><xsl:element name="br"/>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
Result
So, let's see what would happen if we applied the above XSLT document to the following XML document:
<tutorials>
<tutorial>
<name>XML Tutorial</name>
<url>http://www.quackit.com/xml/tutorial</url>
</tutorial>
<tutorial>
<name>HTML Tutorial</name>
<url>http://www.quackit.com/html/tutorial</url>
</tutorial>
</tutorials>
