<Troubleshooting Tips>

Found incompatibility between String Manipulation and Python Regular Expression?

Special handling of double quote (") and backslash (\)

When double quote is included in either Regular Expression or String to handle, you must add another set of double quotes from the beginning and at the end of the parameter string.

Example 1

When your Regular Expression statement starts and end with double quotes

"[A-Z]-[0-9][a-z]"

You must add another set of double quotes like below

“"[A-Z]-[0-9][a-z]"”

Example 2

When you have double quotes in your String to handle parameter

90 min video tutorial "Rocket-st1rt"

must become

"90 min video tutorial "Rocket-st1rt""

Similarly, when back slash is included in your Regular Expression statement or in String to handle parameter, then you must add one more backslash to every backslash.

Example 3

C:\users\argos

Must be annotated like

C:\\users\\argos

Furthermore, when you are ending strings with a backslash, you must not only add one more backslash but also add double quote at the top and end of the string and add 2 more backslashes

Example 4

C:\users\argos\

Must become

"C:\\users\\argos\\\\"

These irregular rules are due to Command Line Interpreter rules(CMD.EXE) and Python string literals.

May you search all operations,

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” https://regex101.com/

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

IMPORTANT NOTE

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.

It returns the starting position of the target string when found – see example below.

When you are replacing characters with a space use double quotes “ “.
