Parenthesis () Syntax

Where Applicable

You can use this syntax in business rules and in DTL transformations.

Details

To use parenthesis syntax to access a virtual property, use the following syntax:

message.(multi-valued-property-path)

Where:

• message is a variable that refers to the current message. The name of this variable depends upon the context.

• multi-valued-property-path is a virtual property path that uses the repeating field shortcut () to iterate through every instance of a repeating field, as described earlier in this reference.

The preceding syntax is equivalent to the following method call:

message.GetValueAt("multi-valued-property-path")

If the syntax returns multiple values a, b, and c, they appear in a single string enclosed in <> angle brackets, like this:

<a><b><c>

Example

For example, in an HL7 routing rule, the syntax HL7.(NK1():1) finds the values of the first field in all of the multiple NK1 segments in the HL7 message object represented by the special variable HL7.
