XPath Comparison Operators

A list of comparison operators used in XPath:

Index	Operator	Description
1)	=	It specifies equals to
2)	!=	It specifies not equals to
3)	<	It specifies less than
4)	>	It specifies greater than
5)	<=	It specifies less than or equals to
6)	>=	It specifies greater than or equals to

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 , and 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>
