Hi,I have a text file like: $ more sample.tex aaa \cite{d1,d2},ddd \cite{e1},ccc \cite{f1,f2,f3} bbb\cite{inhibitor}aaa sub read_tex{ open my $fh, '<', @_; while(<$fh>){ if(/cite\{(.+?)\}/){ push @citeditems,split/,/,$1; } } close($fh); } It only extract the first \cite part out, failed to extract the e1, f1, f2, f3 and uncertain number of being cited item out. Can someone give me some suggest regarding how to upgrade the match part? Thanks with best regards,
Your regexp only asks for a single \cite... match in each line. perldoc perlretut Search for "Global Matching" roughly half-way down the page. -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/
