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 |
Let's take an example to demonstrate the usage of comparison operator. Here, we create a table of
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>Output:
