Parsing xml payload and edit it

Question

Hi
I am trying to parse xml payload in sender side.I have inserted a stateless session bean before " local ejbs call sap adapter".But changes made to string are not reflected in xml file.The code written in ejb is as follows
package com.cts.xi;
import java.io.File;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;

          myContext = context;
     private SessionContext myContext;

          XMLPayload pl = msg.getDocument();
          String str = null;
          String str1 = null;
          int m = 0;
          str = new String(pl.getContent());
          /*int[] ra = null;
          for (int i = 0; i < 4; i++) {
               ra<i> = Integer.parseInt(mc.getContextData("rate"));
          try {

               e.setName("SI");
                int k = l * 3;

          str1 += tmp;
          /*for(int i=0;i<e.nodeCount();i++){

          for (int j = 0; j < e.attributeCount(); j++) {
               str1 += e.attribute(j).getName();
               str1 += e.attribute(j).getData();
          for (int i = 0; i < e.elements().size(); i++) {
               Element e1 = (Element) e.elements().get(i);
               spc += 3;
               traverseXML(e1, str1,m);
               spc -= 3;
          return str1;
Thanking you in advance.

Answer 1

xml or plist , just the extension differs.(Both are Extended Markup Language).
If u want to edit it manually - u can use property list editor (which is in XCode )
or u can open with dashcode , which can be edited easily.
If ur question was to edit dynamically.
U can do that with write to file functionality.
For example u may check this.
