Regular expression to return all characters between two special characters

Question

How would I go about using regx to return all characters between two brackets. Here is an example:

foobar[\'infoNeededHere\']ffffd
needs to return infoNeededHe         


        

Answer 1

^.*\['(.*)'\].*$ will match a line and capture what you want in a group.

You have to escape the [ and ] with \

The documentation at the rubular.com proof link will explain how the expression is formed.
