AnyData::Format::HTMLtUser(Contributed Perl DocumAnyData::Format::HTMLtable(3)NAME
HTMLtable - tied hash and DBI/SQL access to HTML tables
SYNOPSIS
use AnyData;
my $table = adHash( 'HTMLtable', $filename );
while (my $row = each %$table) {
print $row->{name},"\n" if $row->{country} =~ /us|mx|ca/;
}
# ... other tied hash operations
OR
use DBI
my $dbh = DBI->connect('dbi:AnyData:');
$dbh->func('table1','HTMLtable', $filename,'ad_catalog');
my $hits = $dbh->selectall_arrayref( qq{
SELECT name FROM table1 WHERE country = 'us'
});
# ... other DBI/SQL operations
DESCRIPTION
This module allows one to treat the data contained in an HTML table as
a tied hash (using AnyData.pm) or as a DBI/SQL accessible database
(using DBD::AnyData.pm). Both the tiedhash and DBI interfaces allow
one to read, modify, and create HTML tables from perl data or from
local or remote files.
The module requires that CGI, HTML::Parser and HTML::TableExtract are
installed.
When reading the HTML table, this module is essentially just a pass
through to Matt Sisk's excellent HTML::TableExtract module.
If no flags are specified in the adTie() or ad_catalog() calls, then
TableExtract is called with depth=0 and count=0, in other words it
finds the first row of the first table and treats that as the column
names for the entire table. If a flag for 'cols' (column names) is
specified in the adTie() or ad_catalog() calls, that list of column
names is passed to TableExtract as a headers parameter. If the user
specifies flags for headers, depth, or count, those are passed directly
to TableExtract.
When exporting to an HTMLtable, you may pass flags to specify
properties
of the whole table (table_flags), the top row containing the column
names
(top_row_flags), and the data rows (data_row_flags). These flags
follow
the syntax of CGI.pm table constructors, e.g.:
print adExport( $table, 'HTMLtable', {
table_flags => {Border=>3,bgColor=>'blue'};
top_row_flags => {bgColor=>'red'};
data_row_flags => {valign='top'};
});
The table_flags will default to {Border=>1,bgColor=>'white'} if none
are specified.
The top_row_flags will default to {bgColor=>'#c0c0c0'} if none are
specified;
The data_row_flags will be empty if none are specified.
In other words, if no flags are specified the table will print out with
a border of 1, the column headings in gray, and the data rows in white.
CAUTION: This module will *not* preserve anything in the html file except
the selected table so if your file contains more than the selected table,
you will want to use adTie() or $dbh->func(...,'ad_import') to read the
table and then adExport() or $dbh->func(...,'ad_export') to write
the table to a different file. When using the HTMLtable format, this is the
only way to preserve changes to the data, the adTie() command will *not*
write to a file.
