You are here: Strings > StringReplacer


Replaces substrings matching a string or regular expression in the string contained in the source attribute.  



In this example, a pure substitution of text is made without any use of regular expression functionality. This is the simplest kind of substring replacement.

   Source String: Bobby

   Text to Find: obb

   Replacement Text: ill

   Use Regular Expression: no

   Case Sensitive: yes

   Result: Billy

In this example, a pattern matching zero or more ’b’ characters is replaced with nothing.

   Source String: Bobby

   Text to Find: b*

   Replacement Text:

   Use Regular Expression: yes

   Case Sensitive: yes

   Result: Boy

In this example, a pattern matching zero or more ’b’ characters followed by a y is duplicated in the result (prepended by hyphens)

   Source String: Bobby

   Text to Find: b*y

   Replacement Text: --\\0-\\0

   Use Regular Expression: yes

   Case Sensitive: yes

   Result: Bo--bby-bby
