DVAL expressions return dimension values. Although the DVAL MATCH expression is not deprecated, we strongly recommend that you use the PROP_MAPPER element to perform property and dimension value mapping operations.

The DVAL MATCH expression is used to perform text matching within one or more dimensions. The dimensions are specified in DIMENSION_ID EXPRNODE elements. Specify the values to match in one or more PROPERTY expressions. The expression returns a set of matching dimension values. This is useful within a VOID ADD_DVAL expression that contains PROPERTY IDENTITY sub-expressions, to assign the dimension values matching each record’s property values to the record.

You can adjust the behavior of the DVAL MATCH expression by nesting EXPRNODE elements within the DVAL MATCH expression. The nested expression node has a NAME attribute that specifies how to adjust the behavior.

The following list provides the supported values of the NAME attribute and describes their effects on the behavior of DVAL MATCH.

See the EXPRESSION element for DTD and attribute information.
