=head1 NAME

XML::XSS::Text - XML::XSS text stylesheet rule

=head1 VERSION

version 0.3.5

=head1 SYNOPSIS

    use XML::XSS;

    my $xss = XML::XSS->new;

    my $txt_style = $xss->text;

    $txt_style->set_pre( "=pod\n" );
    $txt_style->set_post( "=cut\n" );

    print $xss->render( '<doc>yadah yadah</doc>' );

=head1 DESCRIPTION

A C<XML::XSS> rule that matches against the text nodes of a
document to be rendered.  

=head1 RENDERING ATTRIBUTES

For a document, the displayed attributes follow the template:

    pre
    [text]
    post

=head2 pre

Printed before the text.

=head3 getter - pre()        

=head3 setter - set_pre( $pre )

=head2 replace 

If defined, its value is used instead of the original text.

=head2 filter

Can only accept a sub reference. If defined, the text will be passed 
to the function as C<$_> and the returned value will be printed out.  Still is applied
even if C<replace> is used.

    $xss->set( '#text', {
        filter => sub { uc },
    } );

=head2 post

Printed after the text.

=head3 getter - post()        

=head3 setter - set_post( $post )

=head2 process

If it resolves to false, skip the element altogether.

=head3 get_process()

Attribute getter.

=head3 set_process( $process )

Attribute setter.
