Need Help??

in reply to Re: printing LAST_MATCH_START/@- LAST_MATCH_END/@+ array where regex match begin/end
in thread printing LAST_MATCH_START/@- LAST_MATCH_END/@+ array where regex match begin/end

thank's for the tip. and works fine and get the expected results. good thank's :)))

However I find that that PerlDoc https://perldoc.perl.org/perlvar#Variables-related-to-regular-expressions
is a bit misleading when it says that indexes/positions before and after regex match can be found in the LAST_MATCH_START/@- and LAST_MATCH_END/@+ array by printing

print  $+[0], " ",$+[1], " ", $+[2], "\n" ;

again thank's for the tip :)))

Makes sense to me... `'abcdef' =~ /b(.)(.)./ and print "end of entire match ", $+[0], " en +d of first group ",$+[1], " end of second group ", $+[2], "\n";` [download] outputs: `end of entire match 5 end of first group 3 end of second group 4` [download] This is exactly as expected.
