I added the following code to the Message class:
public void setAttribute(String xpath, String value) throws DOMException {
Element msgXML = getContent();
if(msgXML!=null) {
Attr attribute = msgXML.getAttributeNode(xpath);
if(attribute==null)
throw new DOMException(DOMException.NOT_FOUND_ERR,
"Attribute not found in message with xpath: "+xpath);
else
attribute.setValue(value);
}
}
Does this for everyone? If so, how do I (or can someone) add this to our
latest build?
