"*" is greedy (=searches backwards from the right end), so that won't
do the right thing if you have multiple delimiters
to fix this, use "*?" instead.

(Dot.) In the default mode, this matches any character except
a newline. If the DOTALL flag has been specified, this matches any
character including a newline.
to fix this, pass in re.DOTALL or re.S as the flag argument, or
prepend (?s) to the expression.
