I have a file in the following format:
Data Data Data [Start] Data I want [End] Data
I'd like to grab the Data I want from between the [Start] and [End] tags using a Regex. Can anyone show me how this might be done?

To get a substring between two characters:Get the index after the first occurrence of the character. Get the index of the last occurrence of the character. Use the String. slice() method to get a substring between the 2 characters.
The \ is known as the escape code, which restore the original literal meaning of the following character. Similarly, * , + , ? (occurrence indicators), ^ , $ (position anchors) have special meaning in regex. You need to use an escape code to match with these characters.
i) makes the regex case insensitive. (? s) for "single line mode" makes the dot match all characters, including line breaks.
\[start\](.*?)\[end\] Zhich'll put the text in the middle within a capture.

\[start\]\s*(((?!\[start\]|\[end\]).)+)\s*\[end\] This should hopefully drop the [start] and [end] markers as well.
