Searching for UUIDs in text with regex

I agree that by definition your regex does not miss any UUID. However it may be useful to note that if you are searching especially for Microsoft’s Globally Unique Identifiers (GUIDs), there are five equivalent string representations for a GUID:

"ca761232ed4211cebacd00aa0057b223" 

"CA761232-ED42-11CE-BACD-00AA0057B223" 

"{CA761232-ED42-11CE-BACD-00AA0057B223}" 

"(CA761232-ED42-11CE-BACD-00AA0057B223)" 

"{0xCA761232, 0xED42, 0x11CE, {0xBA, 0xCD, 0x00, 0xAA, 0x00, 0x57, 0xB2, 0x23}}"
