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.

Employee.xml

 <?xml version = “1.0”?> <?xml-stylesheet type = “text/xsl” href=”../employee.xsl”?>  <class>     <employee id = “001”>       <firstname>Aryan</firstname>        <lastname>Gupta</lastname>        <nickname>Raju</nickname>        <salary>30000</salary>    </employee>     <employee id = “024”>        <firstname>Sara</firstname>        <lastname>Khan</lastname>        <nickname>Zoya</nickname>        <salary>25000</salary>    </employee>     <employee id = “056”>        <firstname>Peter</firstname>        <lastname>Symon</lastname>        <nickname>John</nickname>        <salary>10000</salary>     </employee>  </class> 

Employee.xsl

 <?xml version = “1.0” encoding = “UTF-8”?> <xsl:stylesheet version = “1.0”  xmlns:xsl = “http://www.w3.org/1999/XSL/Transform”>       <xsl:template match = “/”>        <html>           <body>              <h2>Employee</h2>              <table border = “1”>                 <tr bgcolor = “pink”>                    <th>ID</th>                    <th>First Name</th>                    <th>Last Name</th>                    <th>Nick Name</th>                    <th>Salary</th>                 </tr>                 <xsl:for-each select = “class/employee”>                 <xsl:sort select = “lastname”/>                       <tr>                       <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>                      </tr>                 </xsl:for-each>              </table>           </body>        </html>   </xsl:template>   </xsl:stylesheet>
