Variable structures are graphical representations of variables or variable paths that are displayed in the editor. They can help you visualize the variable structure, and you can use them to construct inline XQuery expressions that reference the content of the variable.
Note: | Variable structures do not create variables. Variables are created at runtime as the target of the Assign action in the stage. |
AquaLogic Service Bus provides several predefined message context variables (attachments
, body
, header
, outbound
, and inbound
), whose contents you can display as variable structures. You can also define your own variable structures.

The right side of the page provides a workspace for constructing the XQuery expression, XQuery condition, or XPath. The workspace is different in the three editors.
In all three editors, the Property Inspector is displayed on the bottom right of the page. When you select an item from one of the palettes to add to the expression, that item appears in the Property Inspector. You can then paste the item into the workspace.
