SYNOPSIS

To clean a string you can pass a scalar to the function whitespace_filter().

    use HTML::Template::Compiled::Filter::Whitespace qw(whitespace_filter);

    my $clean_html = whitespace_filter($unclean_html);

If you are using HTML::Template::Compiled and want to clean the Template before parsing you can use the function get_whitespace_filter:

    use HTML::Template::Compiled::Filter::Whitespace qw(get_whitespace_filter);

    my $htc = HTML::Template::Compiled->new(
        tagstyle  => [qw(-classic -comment +asp)],
        filter    => get_whitespace_filter(),
        scalarref => \$scalar,
    );

If you are using HTML::Template::Compiled and want to clean the output do both or only this:

    use HTML::Template::Compiled::Filter::Whitespace qw(whitespace_filter);

    my $clean_html = whitespace_filter( $htc->output() );

If you want to disable the filter set the global variable DEBUG to something true.

    $HTML::Template::Compiled::Filter::Whitespace::DEBUG = 1;
