The XML Port Manager window lets you create queries against the XML source file, to define one or more output data streams.
XML source view – displays the contents of the source document.
Data Model tab – displays a relational view of the source document.
Reference tab – displays the available component variables.
Output port area – used to write queries against the data model, and send the results to a particular output port. Although XML Port Manager is, by default, configured with one output port, you can add ports, and write additional queries.
