The message tree

A message tree is a structure that is created by one or more parsers when an input message bit stream is received by a message flow or by the action of a message flow node.

A message is used to describe:

WebSphere Message Broker routes and manipulates messages after converting them into a logical tree. The process of conversion, called parsing, makes the content and structure of a message obvious, and simplifies later operations. After the message has been processed, the parser converts it back into a bit stream.

WebSphere Message Broker supplies a range of parsers to handle the many different messaging standards in use. In some cases WebSphere Message Broker will be able to parse your message automatically. Alternatively, the MRM provides a powerful method of modeling messages that you need to process.

After a message has been parsed, it can be processed in a message flow.

The logical tree contains identical contents to that of the message but is easier to manipulate within the message flow. The message flow nodes provide an interface to query, update or create the content within the tree.
