GUID regex

Below is a simple regular expression to match a guide in a given string:

"^(?:\\{{0,1}(?:[0-9a-fA-F]){8}-(?:[0-9a-fA-F]){4}-(?:[0-9a-fA-F]){4}-(?:[0-9a-fA-F]){4}-(?:[0-9a-fA-F]){12}\\}{0,1})$"

Test it!
/^(?:\{{0,1}(?:[0-9a-fA-F]){8}-(?:[0-9a-fA-F]){4}-(?:[0-9a-fA-F]){4}-(?:[0-9a-fA-F]){4}-(?:[0-9a-fA-F]){12}\}{0,1})$/

True

False

Enter a text in the input above to see the result

Example code in Python:

import re

# Validate GUID
words_pattern = "^(?:\\{{0,1}(?:[0-9a-fA-F]){8}-(?:[0-9a-fA-F]){4}-(?:[0-9a-fA-F]){4}-(?:[0-9a-fA-F]){4}-(?:[0-9a-fA-F]){12}\\}{0,1})$"
re.match(words_pattern, '51d52cf1-83c9-4f02-b117-703ecb728b74') # Returns Match object
re.match(words_pattern, '{51d52cf1-83c9-4f02-b117-703ecb728b74}') # Returns Match object
re.match(words_pattern, '{51d52cf1-83c9-4f02-b117-703ecb728-b74}') # Returns None

# Extract GUID from a string
words_extract_pattern = "(?:\\{{0,1}(?:[0-9a-fA-F]){8}-(?:[0-9a-fA-F]){4}-(?:[0-9a-fA-F]){4}-(?:[0-9a-fA-F]){4}-(?:[0-9a-fA-F]){12}\\}{0,1})"
re.findall(words_extract_pattern, 'Resource {51d52cf1-83c9-4f02-b117-703ecb728b74} is down') # returns ['{51d52cf1-83c9-4f02-b117-703ecb728b74}']
