Regex search to find text between two characters

You can use the below regular expression syntax to find the text between any two given characters:

(?<=\()(.*?)(?=\))

. . . in this search we are looking for text between two parentheses, so we need to use a back slash to escape where the open parens is referenced, and before where the closed parens is placed in the search.

If you want to change the search to look for any text between square brackets it would be modified like this:

(?<=\[)(.*?)(?=\])

If you are looking for text between delimiters which are not part of regular expression syntax, modify the search like this:

(?<=XX)(.*?)(?=XX)
