in reply to Print a previous to previous of a matching line

Hi,

in this case I would take the following approach:

#!/usr/bin/env perl use strict; use warnings; use 5.010; # read first line assuming it is a kind of block seperator my $bsep = <>; $/ = $bsep; while(defined(my $block = <>)) { chomp $block; my @records = split /\n/, $block; next if @records < 3; # malformed block foreach my $record (@records) { say $record; } say "========================"; }

Now you can find and operate on every block how you like.

Best regards
McA

[james28909]: ok maybe i need to ask this question in sopw and not CB but here goes
[james28909]: i am manually parsing html, and am trying to wrap my head around keeping up with tag counts
[james28909]: i can extract a certain tree manually by regexing the html file for a starting anchor, then i send the position of the match to a sub and then seek to that position in the file and keep up with div tags (for now)
