See more XML Examples

Demonstrates how to traverse all nodes in an XML tree.

Note: This example requires Chilkat v9.5.0.77 or greater.

import com.chilkatsoft.chilkat2.StringBuilder;
import com.chilkatsoft.chilkat2.Xml;

public class ChilkatExample {

    public static void main(String[] args) {
        // Use the NextInTraversal2 method to traverse all nodes in the XML tree rooted at the caller.

        Xml xml = new Xml();

        xml.loadXmlFile("qa_data/xml/twoPigs.xml");

        // This is the XML traversed in this example:

        //                       The animals were seldom fed and rats would eat the newborn piglets.
        //                       When Molly was found at one week old, she was the only piglet of
        //                       her siblings who did not get stepped on by a cow. She is a sweet,
        //                       friendly pig who likes to hang out on Cathy's porch on the lounge
