Text between RegEx Python pattern matching

Question

I need help with the following template, I am afraid for many hours. I have text like:

<<12/24/2015 00:00  userrrr>>
********** Text all char and symbols ************
<<12/24/2015 00:00 CET userr>>
Text all char and symbols
<<12/24/2015 00:00 GMT+1 userrrr>> Text in same line
<<12/24/2015 00:00 CET userrr>>
Text all characters and symbols
<<12/24/2015 00:00 GMT+1 userrrrrrr>> Text in same line
More Text all characters and symbols
<<12/24/2015 00:00 CET userrrrr>>
More text all characters and symbols
<<12/24/2015 00:00 CET userrrrrrrrrrr>>
More Text all characters and symbols

Using the template:

(\<<)(\d{2}/\d{2}/\d{4}\s\d{2}:\d{2})(.*?(?=>>))(>>)

The time and time between the arrows correspond correctly. Unfortunately, I cannot find a way to extract text between patterns. The final groups should look like (left_arrows), (datetime), (user), (right_arrows), (text). The closer I got, the it was:

(\<<)(\d{2}/\d{2}/\d{4}\s\d{2}:\d{2}\s\D{3}.*?(?=\s))\s(.*?(?=>>))(>>)((?s).*?(?=<<\d{2}/\d{2}))

But it does not match the first and last correctly. Click here to check the result (pythex.org)

Answer 1

(\<<)(\d{2}/\d{2}/\d{4}\s\d{2}:\d{2}\s\D{0,3}.*?(?=\s))\s(.*?(?=>>))(>>)((?s).*?(?=<<\d{2}/\d{2}|$))
                                                                                                ^^

You need to give |$for the last line to match. See the demo.
