Regex Tester & Validator

This regular expression matches the phrase 'circuit Id' or 'circuit id' (case-insensitive for the 'id' part) followed by whitespace, a non-word character (such as a colon, dash, or equals sign), and then captures a sequence of word characters. It is designed to extract circuit identifiers or names from text where they are labeled with 'circuit Id' or 'circuit id'. Use cases include parsing configuration files, log files, or structured documents to retrieve circuit references for further processing or validation.
