Hi Friend,

Try the following code:

import java.io.*;
import javax.xml.parsers.*;
import javax.xml.transform.*;
import javax.xml.transform.dom.*;
import javax.xml.transform.stream.*;
import javax.xml.xpath.*;
import org.w3c.dom.*;
import org.xml.sax.*;

public class DOMParser {
static String inputFile = "buyer.xml";
static String outputFile = "C:/hello.xml";

public static void main(String[] args) throws Exception {
Document doc = DocumentBuilderFactory.newInstance().newDocumentBuilder().parse(new InputSource(inputFile));

new DOMParser().edit(doc);
Transformer xformer = TransformerFactory.newInstance().newTransformer();
xformer.transform(new DOMSource(doc), new StreamResult(new File(outputFile)));
}

public void edit(Document doc) {
NodeList list = doc.getElementsByTagName("Order");
Node node1 = list.item(0);
Element element1 = (Element)node1;
NodeList list1 = element1.getElementsByTagName("BuyersID");
for (int idx = 0; idx < list1.getLength(); idx++) {
list1.item(idx).setTextContent("id1");
}

Node node2 = list.item(1);
Element element2 = (Element)node1;
NodeList list2 = element1.getElementsByTagName("utcc:IssueDateTime");
for (int idx = 0; idx < list2.getLength(); idx++) {
list2.item(idx).setTextContent("09-12-2009");
}

Node node3 = list.item(2);
Element element3 = (Element)node1;
NodeList list3 = element1.getElementsByTagName("utcc:KCIType");
for (int idx = 0; idx < list3.getLength(); idx++) {
list3.item(idx).setTextContent("A");
}
}
}

Thanks
