User-defined parsers

A user-defined parser is a program that interprets the bit stream of an incoming message and creates an internal representation of the message in a tree structure. A user-defined parser can also regenerate a bit stream for an outgoing message from the internal message tree representation

Create a user-defined parser when the WebSphere® Message Broker parsers are not sufficient to parse user-defined messages.

Do not use user-defined parsers to provide connectivity or transformation functions. In most cases, the MRM or other IBM® supplied parsers are capable of passing most standard type of format. You can also parse a message and construct a message tree in a user-defined node without the need to write a parser. For example, a user-defined node that reads emails from a POP3 server can parse the email and construct a message tree without the need to write a user-defined parser.

If the parser is going to be used only in a user-defined node, you do not need to use a user-defined parser. However, consider a user-defined parser if the parser will be called from other message flow nodes.
