Hi experts,

please help me with the java mapping code to edit the xml as given below:

Input:

<?xml version="1.0"?>

<Record>    

     <ConfigTables>

          <tablename action="SQL_DML">

               <access>some text</access>

          </tablename>

     </ConfigTables>

     <ConfigTables>

           <tablename action="SQL_DML">

               <access>some text</access>

          </tablename>

     </ConfigTables>

</Record>

Output:

<?xml version="1.0"?>

<Record>    

     <ConfigTables>

          <tablename action="SQL_DML">

               <access>updated text</access>

          </tablename>

     </ConfigTables>

     <ConfigTables>

           <tablename action="SQL_DML">

          </tablename>

     </ConfigTables>

</Record>
