XPath Predicate

Predicate specifies XPath expressions written in square bracket. It is used to restrict the selected nodes in a node set for some conditions. See the use of predicate in the "employee" example.

Employee.xml

Index Predicate Description
1) /class/employee[1] It will select first employee element which is child of the class element.
2) /class/employee[last()] It will select last employee element which is child of the class element.
3) /class/employee[@id = 002] It will select employee element where id is 002.
4) /class/salary[salary > 10000] It will select employee element where salary is greater than 10000.

XPath Predicate Example

Let's take an example to create a table of <employee> element with their details, by iterating over each employee. This example uses predicate to calculate the position of the employee node and then print the employee details.

Employee.xml

Employee.xsl

Output:

XPATH Predicate 1

Note:In the above example, you can see that all four queries are fetched.
