Regex Editor & Tester

Matches an entire EDIFACT ORDERS message detail section, starting at a LIN (line item) segment at the beginning of a line and greedily capturing everything, including newlines, up to but not including the UNS section-control segment. The multiline flag anchors ^ to each line start, while the positive lookahead ensures the UNS delimiter terminates the match without being consumed. Commonly used in EDI parsing to extract all item lines from an ORDERS96B interchange for downstream processing of order detail data.
