Receive zipfile with sender file adapter

Question

Hello,
I need to receive one zipped file (binary data) with the file sender adapter. This zipped file contains an xml file that I need to process.
What is the best way to do this?
I have looked into writing an adapter module to unzip or base64 encode the file before sending it further into xi from the module chain.
However, it looks like only xmlpayload is available to the adapter modules (and attachments, but in this case there are none). In the module I have the following relevant code (lots of try catch surrrounding)
          Object obj = null;
          Message msg = null;     
          obj = inputModuleData.getPrincipalData();
          msg = (Message) obj;
          XMLPayload xmlpayload = msg.getDocument();
I end up with an xml payload, that is the zip file in my case.
Is it safe to do something like this
     InputStream is = xmlpayload.getInputStream();
        // zip data into string
     String str = is.toString();
        // base64 encode
     str = MimeUtility.encodeText(str,"base64");
     xmlpayload.setContent(str.getBytes());
        // send the base64 encoded data to XI
        // that is now at least utf-8 text
        return inputModuleData;     
What do you recommend?
Best regards
/Otto
