Adding XPath Functions
See Also
XPath functions are added to manipulate the data before adding the data to the outgoing message.
The Design view Palette contains a collection of supported XPath functions. The Design view Palette opens whenever the Design view is active.
To add an XPath function:
-
Be sure the Palette is visible. If the Palette is not visible, choose Window > Palette from the main menu (Ctrl+Shift-8).
-
Select a required function and drag the pointer to the Transformations pane. A function box appears in the Transformations Pane. Depending on the function, the function box has one or more connectors.
-
Map any arguments into the appropriate connector on the left side of the function box. The source can be a node in the Source tree pane or the output from another function box.
-
Map the result from the right side of the function box. The destination can be a node in the Destination tree pane or the input into another function box.
To delete an XPath function:
-
Select the function box and press Delete.
-
Of particluar importance is the XPath Expression function. This function is used to add an XPath expression not covered by other functions or any other arbitrary XPath expression. Currently, relative location paths and location paths with predicates are not supported. For more information, see The Expression Builder.
