java.lang.Objectorg.apache.jmeter.functions.AbstractFunction
org.apache.jmeter.functions.XPath
public class XPath
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.

public String execute(SampleResult previousResult, Sampler currentSampler) throws InvalidVariableException
N.B. execute() should be synchronized if function is operating with non-thread-safe objects (e.g. operates with files).
JMeter ensures setParameters() happens-before execute(): setParameters is executed in main thread, and worker threads are started after that.
