Smallest possible match

Regular expression smallest match.
I need one regular expression to extract all the opening tag, closing tag and all the strings in between opening and closing tag. eg:

Is this all there anything can be here, \n
[]+*403<>??!@#$%^&*()adsfadsf

By default the regular expression [\w|\W] would give the whole string above. To get the three pairs of open and close tag. You do [\w|\W]+?
