Regex Editor & Tester

This regular expression matches the exact domain name 'dev.test.com' when it is strictly bounded by specific delimiters. It uses lookarounds to ensure the target text is preceded by a pipe character, a newline, or the start of the string, and followed by a pipe, a newline, or the letter 'Z' (which likely represents an intended end-of-string \Z sequence). This pattern is ideal for extracting or validating precise domain names in structured, delimited formats like log files or CSV exports.
