Not answering your question, but code such as

    lines = s.split('\n')
    for i in range(len(lines)):
        if lines[i] == '-><-':
            data = []
            for dataline in lines[i+2:i+6]:
                key, value = dataline.split(':', 1)
                data.append(value)
            # do something with data

is clearer imho than any regular expression for this purpose.
