Problem changing XML element in Adapter Module

[Former Member]

Hey!

I am developing an adapter module to transform a coded password back to clear text. I have access to the XML element where the password is and I get to transform it, but I have 2 problems as also stated in the code:

1) I cannot set the new value back to the node. I try with

firstNode.getFirstChild().setNodeValue(decodedPwd);

but this does not seem to work. How can I achieve this?

2) Between the first issue and the code

msg.setDocument(xmlpayload);

I am not sure how to get my new values for the node back in the XMLPayload. How can I achieve this?

Here is the code:

msg = (Message) inputModuleData.getPrincipalData();

		XMLPayload xmlpayload = msg.getDocument();
			
		factory = DocumentBuilderFactory.newInstance();
		DocumentBuilder builder = factory.newDocumentBuilder();
		Document document = builder.parse((InputStream)xmlpayload.getInputStream());

		password = (Element)document.getElementsByTagName("ns1:passord").item(0);
		firstNode = password.getFirstChild();				
		pwd = firstNode.getNodeValue();

		if(pwd != null){
			decodedPwd = Decoder.decodeString(pwd);
		}


// THIS FAILS!
		firstNode.getFirstChild().setNodeValue(decodedPwd);

//HOW TO SET NEW NODE VALUE TO XMLPAYLOAD HERE?

		msg.setDocument(xmlpayload);
		
		inputModuleData.setPrincipalData(msg);

               return inputModuleData;		

Help is much appreciated!

Thanks!

Hey,

This might sound funny but can you check your code twice? is it really "ns1:passord"??? or "ns1:password"??

Did you have a look at the trace files? I think you will find the problem in that...

Hey!

The problem was solved. The code snipped I found was:

DOMSource DOMSource = new DOMSource(document);

ByteArrayOutputStream myBytes = new ByteArrayOutputStream();

Result dest = new StreamResult(myBytes);

TransformerFactory tf = TransformerFactory.newInstance();

Transformer serializer = tf.newTransformer();

serializer.transform(DOMSource, dest);

byte[] docContent = myBytes.toByteArray();

xmlpayload.setContent(docContent);

msg.getDocument().setContent(xmlpayload.getContent());
