NIST The "insertData(offset,arg)" method will insert a string at the specified character offset. Insert the data in the middle of the character data. Retrieve the character data from the second child of the first employee. The "insertData(offset,arg)" method is then called with offset=9 and arg="Ann". The method should insert the string "Ann" at position 9. The new value of the character data should be "Margaret Ann Martin". Mary Brady 2001-08-17
