RegularExpression

RegularExpression

The
RegularExpression
transformer performs a pattern search on the input text. It replaces instances of the pattern with a specified string.
The following table describes the properties of the
RegularExpression
transformer:
Property
Description
disabled
Determines whether the Script ignores the component and all of the child components. Use this property to test, debug, and modify a Script. You can choose one of the following options:
  • Selected. The Script ignores the component.
  • Cleared. The Script applies the component.
The default is cleared.
exp
Defines a regular expression for the search criterion.
name
A descriptive label for the component. This label appears in the log file and the
Events
view. Use the
name
property to identify the component that caused the event.
optional
Determines whether a component failure causes the parent component to fail. You can choose one of the following options:
  • Selected. Component failure does not cause the parent component to fail.
  • Cleared. Component failure causes the parent component to fail.
Default is cleared. For more information about component failure, see Failure Handling.
remark
A user-defined comment that describes the purpose or action of the component.
replacement
Defines the replacement text.
For example, suppose that a
Content
anchor retrieves the following text:
transformer
You configure the anchor with a
RegularExpression
transformer that searches for the pattern
t.+s
. The pattern means the letter
t
, followed by one or more of characters, followed by the letter
s
. You configure the transformer to replace the pattern with the character
X
.
The pattern matches the substring
trans
of the input. The transformer replaces the substring and outputs:
