XPath Comparison Operator Example

Let’s take an example to demonstrate the usage of comparison operator. Here, we create a table of element with its attribute id and its child <firstname>,<lastname> <nickname> and <salary> by iterating over each employee. It checks salary to be greater than (>) 25000 and then prints the detail.

Employee.xml

  <?xml version = “1.0”?>  <?xml-stylesheet type = “text/xsl” href=”../employee.xsl”?>  <class>     <employee id = “001”>        <firstname>Abhiram</firstname>        <lastname>Kushwaha</lastname>        <nickname>Manoj</nickname>        <salary>15000</salary>     </employee>     <employee id = “002”>        <firstname>Akash</firstname>        <lastname>Singh</lastname>        <nickname>Bunty</nickname>        <salary>25000</salary>     </employee>      <employee id = “003”>        <firstname>Brijesh</firstname>        <lastname>Kaushik</lastname>        <nickname>Ballu</nickname>        <salary>20000</salary>     </employee>      <employee id = “004”>        <firstname>Zoya</firstname>        <lastname>Mansoori</lastname>        <nickname>Sonam</nickname>        <salary>30000</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:if test = “salary > 25000”>                       <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:if>                 </xsl:for-each>              </table>           </body>        </html>     </xsl:template>  </xsl:stylesheet>
