Python: Regex needed

Question

This is probably simple, but I can't figure this out: I need regex expression which would extract following records (Each record may span multiple lines and delimited by one or more blank lines):

TextTextTextTextTextTextText

TextTextTextTextTextTextTextTextText

(one or more blank lines)

TextTextTextTextText

TextTextText

TextTextTextTextTextTextText

(one or more blank lines)

TextTextTextTextText TextTextTextTextTextTextTextTextTextText

Either solution posted so far (Can's or Eli's) will work but you'll probably want to do a .strip() on each of the items returned, and also skip empty strings as you iterate (for cases like quadruple-or-more blank lines, leading/trailing blank lines etc). — Peter Hansen

My solution doesn't generate empty strings or leading/trailing blank lines. — Can Berk Güder

@Can, sure it does, if the text starts with a newline, for example. Or if it ends with two or more newlines. It's trivial to test: re.split(r'\n\n+', '''\ntext\n\ntext\n\n''') — Peter Hansen
