Module Adapter - String Change in XML

Question

Module Adapter
I have been reading "How to Create Modules for the J2EE Adapter Engine" and am trying to implement an adapter module to change a few strings in the message.
I understand I can grab the XI message using the getPrincipalData such as:
// get the XI message from the environment
Message msg = (Message) inputModuleData.getPrincipalData();
and return the message using:          
// provide the XI message for returning
inputModuleData.setPrincipalData(msg);
What is the proper method of searching for strings inside this message and changing a value. We have tried the approach of using XSLT and Java maps to change values but the items we need to change need to occur at the adapter level. Any sample code around changing payload information in an adapter module would be appreciated.
Regards

Hi,
The methods which you use with SAX parser are:
1) Start of the document(startDocument)
2) start of the element(startElement)
3) end of the element(endElement)
4) end of the document(endDocument)
5) chars()
Build your logic using these. These blogs should help you in the process:

You could write the java code in the process method of your bean or you could call the class from the process method.
What exactly do you mead by testng the adapter module? You could test your the java code i.e the SAX parser as you would test any standalone java code. You would be using the same in your bean.
