XML : How to edit contain inside SOAPMessageContext or SOAPMessage

Good day,

  public boolean handleMessage(SOAPMessageContext context) {      SOAPMessage message = context.getMessage( );      ByteArrayOutputStream baos = new ByteArrayOutputStream( );      message.writeTo( baos );      System.out.println(baos.toString());  }    

From the above code, handleMessage() pass in a SOAPMessageContext, and I convert it to message, and then write to ByteArrayOutputStream.

Last step I print it out. For example, I get: <auditNo>577849</auditNo><userName>1159496maker1</userName>

I want to edit the output to become like <userName>1159496maker1</userName> only, means I will remove the auditNo element from this xml.

I can do it by using String replace method: baos.toString( ).replace()

But I think this is not a best practice, I think it should has some simple/best practice method that can control in SOAPMessage level.

Kindly advise.
