Re: Re: Using HTML::Parser extract text from tables

Giving thought to the problem of nested subs I rewrote it as a module and fixed the error. See the new module. And the following is a test script using it. Just enter the table,row,col and it will print out the text. type quit when done.

If anyone else has any suggestions or improvements for the module I would be glad to hear them.

#!/usr/local/bin/perl -w
use strict;

use Table;

my  $table   = Table->new;
my $content  = join '', ( <DATA> );

$table->parse_it(\$content);
print "INPUT TABLE,ROW,COL: ";
while (my $inp = <STDIN>){
  chomp $inp;
  last if $inp eq 'quit';
  
  my ($x,$y,$z) = split ',', $inp;
  next unless ($x) && ($y) && ($z);
  print $table->[$x][$y][$z],"\n" if $table->[$x][$y][$z];
  print "INPUT TABLE,ROW,COL: ";
}
