AnyData::Format::Fixed - tiedhash & DBI/SQL access to Fixed length data
SYNOPSIS
use AnyData;
my $table = adHash( 'Fixed', $filename,'r',{pattern=>'A20 A2'} );
while (my $row = each %$table) {
print $row->{name},"
" if $row->{country} =~ /us|mx|ca/;
}
# ... other tied hash operations
OR
use DBI
my $dbh = DBI->connect('dbi:AnyData:');
$dbh->func('table1','Fixed', $filename, {pattern=>'A20 A2'},'ad_catalog');
my $hits = $dbh->selectall_arrayref( qq{
SELECT name FROM table1 WHERE country = 'us'
});
# ... other DBI/SQL operations
DESCRIPTION
This is a parser for fixed length record files. You must specify an unpack pattern listing the widths of the fields e.g. {pattern=>'A3 A7
A20'}. You can either supply the column names or let the module get them for you from the first line of the file. In either case, they
should be a comma separated string.
Please refer to the documentation for AnyData.pm and DBD::AnyData.pm for further details.

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},"
" 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.
