in reply to Re^2: get n lines before a pattern
in thread get n lines before or after a pattern
Yes, the changes to the file in the OP certainly require an updated approach. What have you tried?
I would loop through the file saving each key and either pushing to a data structure if the name matches or resetting and continuing.
Pseudo code for the loop and structure I'd use:
my @matches; my $FOUND = 0; my %info = {}; while (<INFILE>) { chomp $_; if (($_ =~ /^id/) and ($FOUND)) { push @matches \%info; $FOUND = 0; %info = {} } if ($_ =~ /^id/) { (undef, $info{id}) = split / /, $_} if ($_ =~ /^address/) { (undef, $info{address}) = split / /, $_} if ($_ =~ /^name/) { (undef, $info{fname}) = split / /, $_} ... if ($searchPattern eq $info{fname}) { $FOUND = 1; } }
UPDATE: Added 'chomp' and updated 'split' commands as per kennethk suggestions to me.
