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!
This is some text inside of a div block.

True

False

Enter a text in the input above to see the result

Example code in Javascript:

var guidRegex = /^(?:\{{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})$/;
// Validate GUID
guidRegex.test('51d52cf1-83c9-4f02-b117-703ecb728b74'); // Returns true
guidRegex.test('{51d52cf1-83c9-4f02-b117-703ecb728b74}'); // Returns true
guidRegex.test('{51d52cf1-83c9-4f02-b117-703ecb728-b74}'); // Returns false

// Extract GUID from a string
var guidRegexG = /(?:\{{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})/g;
'Resource {51d52cf1-83c9-4f02-b117-703ecb728b74} is down'.match(guidRegexG); // returns ['{51d52cf1-83c9-4f02-b117-703ecb728b74}']
