the child node are coming like this USER_ID="testpub2" I have to convert xnode and get the value how to covert xml node? and take the value using saxparser. is can I take the value directly?

The below code converts a String to an XML document. Once you have the document, you can navigate the nodes or you can write to a file etc.

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

public class Util {

    public static Document stringToDom(String xmlSource) 
            throws SAXException, ParserConfigurationException, IOException {
        DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
        DocumentBuilder builder = factory.newDocumentBuilder();
        return builder.parse(new InputSource(new StringReader(xmlSource)));
    }
}

public void writeFile(String yourXML){
    BufferedWriter out = new BufferedWriter(new FileWriter("outfilename.xml"));
    try { 
        out.write(yourXML);
    } catch (IOException e) {
        e.printStackTrace();
    } finally {
        out.close();
    }
}
