XSLT <xsl:sort> Element Example

Let's take an example to create a table of <employee> element with its attribute "id" and its child <firstname> , <lastname> , <nickname> , and <salary> by iterating over each student sort them by last name.


<?xml version = "1.0"?>
<?xml-stylesheet type = "text/xsl" href = "employee.xsl"?> 
   <employee id = "001">
   <employee id = "024"> 
   <employee id = "056"> 


<?xml version = "1.0" encoding = "UTF-8"?>
<xsl:stylesheet version = "1.0" 
xmlns:xsl = "http://www.w3.org/1999/XSL/Transform">   
   <xsl:template match = "/"> 
            <table border = "1"> 
               <tr bgcolor = "pink"> 
                  <th>First Name</th> 
                  <th>Last Name</th> 
                  <th>Nick Name</th> 
               <xsl:for-each select = "class/employee"> 
               <xsl:sort select = "lastname"/> 
                     <td><xsl:value-of select = "@id"/></td> 
                     <td><xsl:value-of select = "firstname"/></td> 
                     <td><xsl:value-of select = "lastname"/></td> 
                     <td><xsl:value-of select = "nickname"/></td> 
                     <td><xsl:value-of select = "salary"/></td>
