HTML::TableExtract with a table inside of a table - perl

Question

I have a small script that I am using to manipulate the code from a remote URL (code is separate). The manual page for HTML::TableExtract has the following code section relating to doing a table-in-a-table extract, ie
$te = new HTML::TableExtract
(
headers => [qw(Summary Region)],
chain => [
{ depth => 0, count => 2 },
{ headers => [qw(Part Qty Cost)] }
],
);
My code contains this, ie:
use HTML::TableExtract;
use strict;
use warnings;
my $te = new HTML::TableExtract
(
headers => [qw(Incident Date Time Location Description)],
chain => [
{ depth => 0, count => 2 },
{ headers => [qw(Unit DIS ENR ONS LEF ARR BUS REM COM)] }
],
);
$te->parse_file('data.html');
However, running it gives me this:
Can't locate object method "chain" via package "HTML::TableExtract" at /usr/lib/perl5/HTML/Parser.pm line 80.
Is there something I'm missing? (If anyone has a better way to extract a table from within a table (while printing information from both I'm all ears)

Answer 1

I didn't see any document about chain method in the doc of HTML::TableExtract. Maybe you're using an expired version?
But according to the doc, you could do this using the depth and count attributes:
$te = HTML::TableExtract->new(
headers => [qw(Unit DIS ENR ONS LEF ARR BUS REM COM)],
depth => 1,
count => 1
);
$te->parse($html_string);
depth: Specify how embedded in other tables your tables of interest
should be. Top-level tables in the HTML document have a depth of 0,
tables within top-level tables have a depth of 1, and so on.
count: Specify which table within each depth you are interested in,
beginning with 0.
In your case depth and count should be both 1.
