Not able to extract XML data got in string format

[Deepshan Shetty]

Hi all


I get a xml data in form of a string(never seen such a xml data) but im stuck wid extracting it.

The data is like,
<ABC ONE="1023814" TWO="1234567892" THREE="INR" FOUR="2012-05-25" FIVE="1" SIX="FAILED" />

When i extract dis i get null.

Can anyone send a snippet of code to achieve this functionality, its bit urgent.

How do you extract it and from where? What does your code look like?

Need to extract it in java..

Please Check my code

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

public class XMLParseString
{
   String s_xml_data = null;

    public XMLParseString() {
    }
    
    public void setData(String s_set_data) {
        s_xml_data = s_set_data;
       // System.out.println("inside Bean setdata"+s_xml_data);
    }
    
    public String processData() {
        String s_final_data = null;

        if (s_xml_data != null) {



            try {

                DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
                DocumentBuilder db = dbf.newDocumentBuilder();
                InputSource is = new InputSource();
                is.setCharacterStream(new StringReader(s_xml_data));
                Document doc = db.parse(is);
               
                NodeList nodes = doc.getElementsByTagName("ABC");

                
                



                for (int s = 0; s < nodes.getLength(); s++) {


                    Node first_node = nodes.item(s);

                    if (first_node.getNodeType() == Node.ELEMENT_NODE) {
                        Element firstPersonElement = (Element) first_node;

                        //------------------------------------------------------------------------------------------
                        
                        NodeList firstNameList = firstPersonElement.getElementsByTagName("ONE");
                        Element firstNameElement = (Element) firstNameList.item(0);

                        NodeList textFNList = firstNameElement.getChildNodes();
                        s_final_data = ((Node) textFNList.item(0)).getNodeValue().trim();
                      
                        //System.out.println("s_final_data"+s_final_data);

                    }//end of if clause

                }//end of for loop with s 


            } catch (Exception ex) {
                System.out.println("Exception in xmlParseString ::" + ex);
            }

        }

        return s_final_data;
    }  
}

Okay Sir

Basic things to troubleshoot -
1. Use printStackTrace() on the Exception to find which line creates Exception, if any.
2. Use System.out.print statements to find if the flow of the program.

If you have the node like - <ABC ONE="someValue" TWO="someValue" /> , then ONE and TWO are not Nodes (or Elements) but attributes of the node ABC.

So the correct way to get the value present in the attribute ONE will be like below -

String oneValue = firstPersonElement.getAttribute("ONE");
System.out.println(oneValue);

and hence this won't work.

NodeList firstNameList = firstPersonElement.getElementsByTagName("ONE"); 

Make sure it fails there by using some print statements.
