Test, validate and match regular expressions
Matches a block of text starting with the literal word 'Born' on one line, followed by at least one more line, then captures any number of intermediate lines (in group 1) until reaching a line containing 'Died'. This is useful for extracting biographical content between birth and death markers, such as parsing Wikipedia-style articles, obituaries, or structured life-event records. The global flag finds all such blocks in a document, and the multiline flag enables line-by-line matching.
