All Regular Expression token sequence can be used with exception of a few tokens that are described in Errata here.

To test and capture Regular Expression token sequences, we recommend to use online tools such as “regular expressions 101”

You can simply test and copy/paste the token sequence from the tool and paste in the plugin parameter section.


Please read when handling SPACE by itself.

String Manipulation plugin is almost 100% compatible to standard Regular Expression. Only exception is handling of "space". When handling space alone as a single character, you must use double quotations around space i.e. " ". 

When space is part of the string you try to find, no need to have double quotation. Examples are , (comma and space), a b (a space b), and a + (a space plus).

Finding space can be also done other tokens such as \s.

(warning) Refer to this FAQ contents when you find incompatibility between Regular Expression (Python) and String Manipulation.
