XPath NodeSet in Java

Question

I have this code in eclipse

NodeSet nodes = (NodeSet) xPath.evaluate(expression,inputSource, XPathConstants.NODESET); 

and this gives me a compile-time error in NodeSet.

This is the material that I imported. Can you tell me why this is done?

 import javax.xml.xpath.*; import org.xml.sax.InputSource; import java.io.File; import java.io.FileInputStream; import java.io.FileNotFoundException; import java.util.*;

As indicated, NodeSet is not part of the standard libraries. However, from the documentation, NodeSet maps to NodeList, so you can simply use this instead. Thus, it will become the following:

 NodeList nodes = (NodeList) xPath.evaluate(expression,inputSource, XPathConstants.NODESET); 

You will need to import org.w3c.dom.NodeList .
