Parsing String which comes as xml

[yekkala krishna]

Hi,

In my application I am receiving xml as a String. I want to parse the String now.Below is my xml coming as string.
<m:notify>
<header:standardHeader>
<header:e2e>
<header:E2EDATA>busProcOriginator=IRAMS,busProcType=notify,busTxnType=MENNotifications</header:E2EDATA>
</header:e2e>
<ms1:meNm>ins-2</ms1:meNm>.....

I want to parse the data coming form ms1:meNm tag...

Could you suggest how to solve this issue..

Thanks in Advance..

Too difficult for "beginning Java". Moving thread.

Any XML parser can do that. Check out the DOM and SAX APIs in the javax.xml.parsers package.

Hi Ulf,

I am able to parse xml with the help of DOM parser.But in my application i am getting xml as String format.So please suggest me a better way to solve this issue.

Thanks in advance...

So you have a string. And you want to parse it with a DOM parser. Why do you think there is anything preventing you from doing that?

yekkala , please find the implementation below

  

package com.xml.processing;

import java.io.StringReader;

import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.parsers.ParserConfigurationException;

import org.w3c.dom.CharacterData;
import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.w3c.dom.Node;
import org.w3c.dom.NodeList;
import org.xml.sax.InputSource;


public class StringXML {

	
	
	
	
	
	public static void main(String[] args) {
		try {
			String s ="" +
			
			"<m:notify><ms1:meNm>ins-2</ms1:meNm></m:notify>";
			
			DocumentBuilderFactory dbf =
			    DocumentBuilderFactory.newInstance();
			DocumentBuilder db = dbf.newDocumentBuilder();
			InputSource is = new InputSource();
			is.setCharacterStream(new StringReader(s));
			
		    Document doc = db.parse(is);
		    NodeList nodes = doc.getElementsByTagName("m:notify");

			
		    for (int i = 0; i < nodes.getLength(); i++) {
		           Element element = (Element) nodes.item(i);

		           NodeList name = element.getElementsByTagName("ms1:meNm");
		           Element line = (Element) name.item(0);
		           //getCharacterDataFromElement(line);
		           
		           System.out.println("Name: " + getCharacterDataFromElement(line));
 
		           
		           
		    }
		    
		    
		    
		   
		    
		    
			
		} catch (ParserConfigurationException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}

		
		catch(Exception e){
			
			e.printStackTrace();
		}
		
		
	}
	
	  public static String getCharacterDataFromElement(Element e) {
		    Node child = e.getFirstChild();
		    if (child instanceof CharacterData) {
		       CharacterData cd = (CharacterData) child;
		       return cd.getData();
		    }
		    return "?";
		  }
