VERSION

Version 0.14

SYNOPSIS

    use HTML::TableContent;
    my $t = HTML::TableContent->new();
    
    $t->parse_file('test.html'); 
   
    my @cell_ids = ( );
    foreach my $table ($t->all_tables) {
        push @cell_ids, map { $_->id } @{ $table->get_col('Email') };
    }

    .....

    $t->parse($html);

    my $first_table = $t->get_first_table;
    my $first_row = $first_table->get_first_row;
    
    foreach my $row ($first_table->all_rows) {
        push @column, $row->cells->[0];
    }

DESCRIPTION

Extract content from HTML tables. Create HTML tables from content.

SUBROUTINES/METHODS

parse

Parse $string as a chunk of html.

    $t->parse($string);

parse_file

Parse a file that contains html.

    $t->parse_file($string);

raw

Return underlying data structure

    $t->raw;

render

Render all tables as HTML.

    $t->render;

tables

Array Ref containing HTML::TableContent::Table's

    $t->tables;

all_tables

Array containing HTML::TableContent::Table's

    $t->all_tables;

add_table

Add a new HTML::TableContent::Table.

    $t->add_table({ id => 'my-first-table', class => 'something' });

table_count

Count number of tables found/stored.

    $t->table_count;

get_table

Get table by index.

    $t->get_table($index);

get_first_table

Get first table.

    $t->get_first_table;

get_last_table

Get last table.

    $t->get_last_table;

clear_table

Clear table by array index.

    $t->clear_table($index);

clear_first_table

Clear first table

    $t->clear_first_table;

clear_last_table

Clear last table.

    $t->clear_last_table;

headers_spec

Hash containing all table headers and their occurrence count.

    $t->headers_spec;

filter_tables

Filter all tables by a list of headers, only one header in the list has to match for the filter to run.

    $t->filter_tables(headers => qw/Name Email/);

Filter all tables for a single column.

    $t->filter_tables(header => 'Name');

Sometimes you want a little more flexibility.. i.e you want to keep your tables if none of the headers exist.

    $t->filter_tables(headers => qw/Name Email/, flex => 1);

headers_exist

Pass an Array of headers, if one of the headers match the truth is returned.

    $t->headers_exist(qw/Name Email/);

add_caption_selectors

The majority of people don't use captions, but a title above the table.

This method accepts an array of 'tags', 'ids' or 'classes' and will try to do something sensible which generally means mapping the text to the selector it finds closest to the table.

    my $t = HTML::TableContent->new();

    $t->add_caption_selectors(qw/id-1 id-2 id-3/);

    $t->parse($html);

create_table

Accepts a HashRef of options, it currently requires an Array of Arrays or an Array or Hashes as its data.

    $t->create_table({ aoa => $aoa });

    ...

    $t->create_table({ aoh => $aoh });

It will Assume the first array in the array of arrays is the array containing table headers, or for a hash its keys. You can turn off headers by including the no_headers flag.

    $t->create_table({ aoa => $aoa, no_headers => 1 });

Hashes have no orderd, so to overcome this pass in an array of headers.

    $t->create_table({ aoh => $aoh, order => qw/id name address/ });

You can also set class, id, colspan, rowspan, style.

    my $options = {
        aoa => $aoa,
        table => { id => 'first-table' }, # set the table id
        header => { class => 'headers-class' }, # class 'headers-class' will be set on all headers'
        row => { class => 'rows-class' } # class 'row-class' will be set on all rows'
        cell => { class => 'cells-class' } # class 'cells-class' will be set on all cells'
        rows => [ 
            {
                id => 'first' # id for the first row
                cells => [ # cells belong to rows
                    {
                        id => 'one' # set id on the first cell inside the first row
                    }
                    ...
                ]
            }
            ...
        ],
        headers => [
            {
                id => 'first-header' # set id on the first header
            }
            ...
        ]
    };

    my $table = $t->create_table($options);

EXAMPLES

Text::CSV_XS

    use HTML::TableContent;
    use Text::CSV_XS qw( csv );

    my $aoa = csv ( in => 'test.csv' );

    my $tc = HTML::TableContent->new();

    my $table = $tc->create_table({ aoa => $aoa });

    $table->render;
