Pod::Simple::XHTML(3pm)               Perl Programmers Reference Guide               Pod::Simple::XHTML(3pm)



NAME
       Pod::Simple::XHTML -- format Pod as validating XHTML

SYNOPSIS
         use Pod::Simple::XHTML;

         my $parser = Pod::Simple::XHTML->new();

         ...

         $parser->parse_file('path/to/file.pod');

DESCRIPTION
       This class is a formatter that takes Pod and renders it as XHTML validating HTML.

       This is a subclass of Pod::Simple::Methody and inherits all its methods. The implementation is
       entirely different than Pod::Simple::HTML, but it largely preserves the same interface.

   Minimal code
         use Pod::Simple::XHTML;
         my $psx = Pod::Simple::XHTML->new;
         $psx->output_string(\my $html);
         $psx->parse_file('path/to/Module/Name.pm');
         open my $out, '>', 'out.html' or die "Cannot open 'out.html': $!\n";
         print $out $html;

       You can also control the character encoding and entities. For example, if you're sure that the POD is
       properly encoded (using the "=encoding" command), you can prevent high-bit characters from being
       encoded as HTML entities and declare the output character set as UTF-8 before parsing, like so:

         $psx->html_charset('UTF-8');
         $psx->html_encode_chars('&<>">');

METHODS
       Pod::Simple::XHTML offers a number of methods that modify the format of the HTML output. Call these
       after creating the parser object, but before the call to "parse_file":

         my $parser = Pod::PseudoPod::HTML->new();
         $parser->set_optional_param("value");
         $parser->parse_file($file);

   perldoc_url_prefix
       In turning Foo::Bar into http://whatever/Foo%3a%3aBar, what to put before the "Foo%3a%3aBar". The
       default value is "http://search.cpan.org/perldoc?".

   perldoc_url_postfix
       What to put after "Foo%3a%3aBar" in the URL. This option is not set by default.

   man_url_prefix
       In turning crontab(5) into http://whatever/man/1/crontab, what to put before the "1/crontab". The
       default value is "http://man.he.net/man".

   man_url_postfix
       What to put after "1/crontab" in the URL. This option is not set by default.

   title_prefix, title_postfix
       What to put before and after the title in the head. The values should already be &-escaped.

   html_css
         $parser->html_css('path/to/style.css');

       The URL or relative path of a CSS file to include. This option is not set by default.

   html_javascript
       The URL or relative path of a JavaScript file to pull in. This option is not set by default.

   html_doctype
       A document type tag for the file. This option is not set by default.

   html_charset
       The charater set to declare in the Content-Type meta tag created by default for "html_header_tags".
       Note that this option will be ignored if the value of "html_header_tags" is changed. Defaults to
       "ISO-8859-1".

   html_header_tags
       Additional arbitrary HTML tags for the header of the document. The default value is just a content
       type header tag:

         <meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">

       Add additional meta tags here, or blocks of inline CSS or JavaScript (wrapped in the appropriate
       tags).

       html_encode_chars

       A string containing all characters that should be encoded as HTML entities, specified using the
       regular expression character class syntax (what you find within brackets in regular expressions).
       This value will be passed as the second argument to the "encode_entities" fuction of HTML::Entities.
       IF HTML::Entities is not installed, then any characters other than "&<""'> will be encoded
       numerically.

   html_h_level
       This is the level of HTML "Hn" element to which a Pod "head1" corresponds.  For example, if
       "html_h_level" is set to 2, a head1 will produce an H2, a head2 will produce an H3, and so on.

   default_title
       Set a default title for the page if no title can be determined from the content. The value of this
       string should already be &-escaped.

   force_title
       Force a title for the page (don't try to determine it from the content).  The value of this string
       should already be &-escaped.

   html_header, html_footer
       Set the HTML output at the beginning and end of each file. The default header includes a title, a
       doctype tag (if "html_doctype" is set), a content tag (customized by "html_header_tags"), a tag for a
       CSS file (if "html_css" is set), and a tag for a Javascript file (if "html_javascript" is set). The
       default footer simply closes the "html" and "body" tags.

       The options listed above customize parts of the default header, but setting "html_header" or
       "html_footer" completely overrides the built-in header or footer. These may be useful if you want to
       use template tags instead of literal HTML headers and footers or are integrating converted POD pages
       in a larger website.

       If you want no headers or footers output in the HTML, set these options to the empty string.

   index
       Whether to add a table-of-contents at the top of each page (called an index for the sake of
       tradition).

   anchor_items
       Whether to anchor every definition "=item" directive. This needs to be enabled if you want to be able
       to link to specific "=item" directives, which are output as "<dt>" elements. Disabled by default.

   backlink
       Whether to turn every =head1 directive into a link pointing to the top of the page (specifically, the
       opening body tag).

SUBCLASSING
       If the standard options aren't enough, you may want to subclass Pod::Simple::XHMTL. These are the
       most likely candidates for methods you'll want to override when subclassing.

   handle_text
       This method handles the body of text within any element: it's the body of a paragraph, or everything
       between a "=begin" tag and the corresponding "=end" tag, or the text within an L entity, etc. You
       would want to override this if you are adding a custom element type that does more than just display
       formatted text. Perhaps adding a way to generate HTML tables from an extended version of POD.

       So, let's say you want to add a custom element called 'foo'. In your subclass's "new" method, after
       calling "SUPER::new" you'd call:

         $new->accept_targets_as_text( 'foo' );

       Then override the "start_for" method in the subclass to check for when "$flags->{'target'}" is equal
       to 'foo' and set a flag that marks that you're in a foo block (maybe "$self->{'in_foo'} = 1"). Then
       override the "handle_text" method to check for the flag, and pass $text to your custom subroutine to
       construct the HTML output for 'foo' elements, something like:

         sub handle_text {
             my ($self, $text) = @_;
             if ($self->{'in_foo'}) {
                 $self->{'scratch'} .= build_foo_html($text);
             } else {
                 $self->{'scratch'} .= $text;
             }
         }

   accept_targets_as_html
       This method behaves like "accept_targets_as_text", but also marks the region as one whose content
       should be emitted literally, without HTML entity escaping or wrapping in a "div" element.

   resolve_pod_page_link
         my $url = $pod->resolve_pod_page_link('Net::Ping', 'INSTALL');
         my $url = $pod->resolve_pod_page_link('perlpodspec');
         my $url = $pod->resolve_pod_page_link(undef, 'SYNOPSIS');

       Resolves a POD link target (typically a module or POD file name) and section name to a URL. The
       resulting link will be returned for the above examples as:

         http://search .cpan.org/perldoc? Сеть:: Ping#INSTALL
         http://search .cpan.org/perldoc? perlpodspec
         #SYNOPSIS

       Note that when there is only a section argument the URL will simply be a link to a section in the
       current document.

   resolve_man_page_link
         my $url = $pod->resolve_man_page_link('crontab(5)', 'EXAMPLE CRON FILE');
         my $url = $pod->resolve_man_page_link('crontab');

       Resolves a man page link target and numeric section to a URL. The resulting link will be returned for
       the above examples as:

           http://man.he.net/man5/crontab
           http://man.he.net/man1/crontab

       Note that the first argument is required. The section number will be parsed from it, and if it's
       missing will default to 1. The second argument is currently ignored, as man.he.net
       <http://man.he.net> does not currently include linkable IDs or anchor names in its pages. Subclass to
       link to a different man page HTTP server.

   idify
         my $id   = $pod->idify($text);
         my $hash = $pod->idify($text, 1);

       This method turns an arbitrary string into a valid XHTML ID attribute value.  The rules enforced,
       following <http://webdesign.about.com/od/htmltags/a/aa031707.htm>, are:

       •   The id must start with a letter (a-z or A-Z)

       •   All subsequent characters can be letters, numbers (0-9), hyphens (-), underscores (_), colons
           (:), and periods (.).

       •   Each id must be unique within the document.

       In addition, the returned value will be unique within the context of the Pod::Simple::XHTML object
       unless a second argument is passed a true value. ID attributes should always be unique within a
       single XHTML document, but pass the true value if you are creating not an ID but a URL hash to point
       to an ID (i.e., if you need to put the "#foo" in "<a href="#foo">foo</a>".

   batch_mode_page_object_init
         $pod->batch_mode_page_object_init($batchconvobj, $module, $infile, $outfile, $depth);

       Called by Pod::Simple::HTMLBatch so that the class has a chance to initialize the converter.
       Internally it sets the "batch_mode" property to true and sets "batch_mode_current_level()", but
       Pod::Simple::XHTML does not currently use those features. Subclasses might, though.
