org.apache.jmeter.functions

Class XPath

java.lang.Object

org.apache.jmeter.functions.AbstractFunction

org.apache.jmeter.functions.XPath

All Implemented Interfaces:

org.apache.jmeter.functions.Function

public class XPath
extends org.apache.jmeter.functions.AbstractFunction

The function represented by this class allows data to be read from XML files.

Syntax is similar to the CVSRead function. The function allows the test to line-thru the nodes in the XML file - one node per each test, e.g. inserting the following in the test scripts:

 ${_XPath(c:/BOF/abcd.xml,/xpath/)} // match the (first) node
 ${_XPath(c:/BOF/abcd.xml,/xpath/)} // Go to next match of '/xpath/' expression
 

NOTE: A single instance of each different file/expression combination is opened and used for all threads.

Since:

2.0.3
