The message tree

A message tree is a structure that is created, either 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 obvious the content and structure of a message, 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. See Parsers.

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

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