RegEX does not matches until end of line

Question

I'm trying to extract the String Hex-STRING until the end of line. But what it matches is Hex-STRING: 84 16 F9 B0 05 1F 70 4F 57 4C A8 1F 60 E3 27 A1 E0 CD C4 E9 84 C3 68 53 C4 E9 84 C9 7A BB C4 E9 84 AC.

Something is missing in this expression? I already tried to include $but it does not work.

RegEX: Hex-STRING:\s(.+)

Test String:

iso.3.6.1.4.1.25355.3.2.6.4.2.5.1.7.4.2.13.36 = Hex-STRING: 84 16 F9 B0 05 1F 70 4F 57 4C A8 1F 60 E3 27 A1
E0 CD C4 E9 84 C3 68 53 C4 E9 84 C9 7A BB C4 E9 84 AC 
C3 68 53 27 CC 58 97 84 AC 74 F7 60 E3 27 CC 58 97
84 AC 74 F7 60 E3 27 CC 58 97 84 AC 74 F7 60 E3 27
CC 58 97 
84 AC 74 F7 60 E3 27 C3 68 53 84 AC 74 F7 60 E3 27 CC 
58 97

Python Code

Text File content:

 iso.3.6.1.4.1.25355.3.2.6.3.2.1.11.1.2.4 = STRING: "785c720855c8"
iso.3.6.1.4.1.25355.3.2.6.4.2.5.1.7.1.2.4.9 = Hex-STRING: 84 16 F9 AF CF 75 84 16 F9 AF E1 35 50 C7 BF F2
F8 4B 70 4F 57 3A C6 23 70 4F 57 3E C5 CD

Code:

w = open("text.txt","r")
 for item in w:
  for match in re.findall(r'Hex-STRING:\s*(.+)',item):
   print match

Output:

84 16 F9 AF CF 75 84 16 F9 AF E1 35 50 C7 BF F2

Output Expected:

84 16 F9 AF CF 75 84 16 F9 AF E1 35 50 C7 BF F2
F8 4B 70 4F 57 3A C6 23 70 4F 57 3E C5 CD

It seems to work, see [this demo](https://regex101.com/r/ebNGlI/1), `84 16 F9 B0 05 1F 70 4F 57 4C A8 1F 60 E3 27 A1` is captured. What is the code you are using the regex in? Do you need to match till the end of *line* or *string*? — Wiktor Stribiżew, Oct 09 '18 at 17:24
Hi @WiktorStribiżew I dont have sure how it works, but I thought that that expression should matches `Hex-STRING` and all these numbers, until `.. 27 CC 58 97` — TMoraes, Oct 09 '18 at 17:27
Then you need to add `(?s)`, see [demo](https://regex101.com/r/ebNGlI/2) — Wiktor Stribiżew, Oct 09 '18 at 17:28
Yes, I will updated my question with my code, one moment please — TMoraes, Oct 09 '18 at 17:36
I don't think that question what you marked would resolve this problem, but I'll read and test it @WiktorStribiżew — TMoraes, Oct 09 '18 at 18:28
You need to read the whole file in to make it work, but it *will* work. Remove `for item in w:`, and use `for match in re.findall(r'(?s)Hex-STRING:\s*(.+)', w.read()):` — Wiktor Stribiżew, Oct 09 '18 at 18:30
hmm.. Worked! If I have loop the file and then apply regex, what should I use? — TMoraes, Oct 09 '18 at 18:36
*If I have loop the file* - how do you plan to use a regex spanning across multiple lines then? — Wiktor Stribiżew, Oct 10 '18 at 00:23

You can do it like this:

import re

text = """iso.3.6.1.4.1.25355.3.2.6.4.2.5.1.7.4.2.13.36 = Hex-STRING: 84 16 F9 B0 05 1F 70 4F 57 4C A8 1F 60 E3 27 A1
E0 CD C4 E9 84 C3 68 53 C4 E9 84 C9 7A BB C4 E9 84 AC
C3 68 53 27 CC 58 97 84 AC 74 F7 60 E3 27 CC 58 97
84 AC 74 F7 60 E3 27 CC 58 97 84 AC 74 F7 60 E3 27
CC 58 97
84 AC 74 F7 60 E3 27 C3 68 53 84 AC 74 F7 60 E3 27 CC
58 97"""

result = re.search("Hex-STRING:\s(.+)$", text, re.DOTALL)
print(result.group())

Output

Hex-STRING: 84 16 F9 B0 05 1F 70 4F 57 4C A8 1F 60 E3 27 A1
E0 CD C4 E9 84 C3 68 53 C4 E9 84 C9 7A BB C4 E9 84 AC
C3 68 53 27 CC 58 97 84 AC 74 F7 60 E3 27 CC 58 97
84 AC 74 F7 60 E3 27 CC 58 97 84 AC 74 F7 60 E3 27
CC 58 97
84 AC 74 F7 60 E3 27 C3 68 53 84 AC 74 F7 60 E3 27 CC
58 97

From the documentation:

If the DOTALL flag has been specified, this matches any character including a newline.
