Thanks Jason,

 

banner = re.compile(r'banner\s+(\w+)\s+(.+)(.*?)\2', re.DOTALL).findall(lines)

 

worked nicely to get what I needed:

 

outfile.write("Banner type: %s     Banner Delimiter: %s\n" % (banner[0][0], banner[0][1]))
outfile.write("Banner Text:\n")
outfile.write(banner[0][2])

 

Probably not the prettiest, most concise code, but it gets the job done.

 

Thanks again,

Marc
