=head1 NAME

XML::Grammar::Screenplay - CPAN distribution implementing an XML grammar for 

=head1 VERSION

Version 0.1.4


our $VERSION = '0.1.4';


See L<XML::Grammar::Screenplay::FromProto>, 
L<XML::Grammar::Screenplay::ToDocBook> and


XML::Grammar::Screenplay is a Perl module for:

=over 4

=item 1. Converting a well-formed plain text format to a specialized XML format.

=item 2. Converting the XML to DocBook/XML or directly to HTML for rendering.


The best way to use it non-programatically is using
L<XML::Grammar::Screenplay::App::ToDocBook> and
L<XML::Grammar::Screenplay::App::ToHTML>, which are modules implementing
command line applications for their processing.

The rest of this page will document the syntax of the custom textual format.

=head1 FORMAT

=head2 Scenes

Scenes are placed in XML-like tags of C<< <section> ... </section> >> or
abbreviated as C<< <s> ... </s> >>. Opening tags in the format may have 
attributes whose keys are plaintext and whose values are surrounded by
double quotes. (Single-quotes are not supported).

The scene tag must have an C<id> attribute (for anchors, etc.) and could
have an optional C<title> attribute. If the title is not specified, it will
default to the ID.

Scenes may be B<nested>. There cannot be any sayings or descriptions (see below)
except inside scenes.

=head2 Text

Text is any of:

=over 4

=item 1. Plaintext

Regular text

=item 2. XML-like tags.

Supported tags are C<< <b> >> for bold text, C<< <i> >> for italics,
C<< <a href="..."> >> for hyperlinks, and an empty C<< <br /> >> tag for line-breaks.

=item 3. Entities

The text format supports SGML-like entities such as C<< &amp; >>,
C<< &lt; >>, C<< &quot; >> and all other entities that are supported by 

=item 4. Text between [ ... ]

Text between square brackets (C<[ ... ]>) is reserved for descriptions
or inline descriptions (see below).


=head2 Sayings

The first paragraph when a character talks starts with the name of the
character followed by a colon (C<:>) and the rest of the text. Like this:

    David: Goliath, I'm going to kill you! You'll see -
    I will.

If a character says more than one paragraph, the next paragraph should start
with any number of "+"-signs followed by a colon:

    David: Goliath, I'm going to kill you! You'll see -
    I will.

    ++++: I will sling you and bing you till infinity!

=head2 Descriptions.

Descriptions that are not part of saying start with a C<[> at the first
character of a line and extend till the next C<]>. They can span several

There are also internal descriptions to the saying which are placed
inside the paragraph of the saying and describe what happens while the
character talks. 


Examples can be found in the C<t/data> directory, and here:

=over 4

=item * The One with the Fountainhead


=item * Humanity - The Movie


=item * Star Trek - "We The Living Dead"




When trying to convert the well-formed text to XML, one will often 
encounter an obscure "Parse Error". This is caused by L<Parse::RecDescent>,
which is used for parsing. The best way I found to deal with it is to
gradually eliminate parts of the document until the offending markup is

In the future, I plan on writing a custom parser that will provide better
diagnostics and will hopefully also be faster.
