Performs a regular expression match on the specified expression.

If the expression matches the pattern, the feature is output via the Matched port, and the portion of the original search string that matched the regular expression is stored in the attribute specified in the Matched Result Attribute (and optionally matching pieces of the expression are stored in the attribute list specified in the All Matches List Name and Subexpression Matches List Name parameters, along with the starting indices of each piece). Otherwise, it is output via the NotMatched port.

Usage Notes



Editing Transformer Parameters

Using a set of menu options, transformer parameters can be assigned by referencing other elements in the workspace. More advanced functions, such as an advanced editor and an arithmetic editor, are also available in some transformers. To access a menu of these options, click beside the applicable parameter. For more information, see Transformer Parameter Menu Options.

Defining Values

There are several ways to define a value for use in a Transformer. The simplest is to simply type in a value or string, which can include functions of various types such as attribute references, math and string functions, and workspace parameters. There are a number of tools and shortcuts that can assist in constructing values, generally available from the drop-down context menu adjacent to the value field.

Dialog Options - Tables

Transformers with table-style parameters have additional tools for populating and manipulating values.
