6 Pod::Xhtml - Generate well-formed XHTML documents from POD format
7 documentation
8
10 This module inherits from Pod::Parser, hence you can use this familiar
11 interface:
12 use Pod::Xhtml;
14 my $parser = new Pod::Xhtml;
15 $parser->parse_from_file( $infile, $outfile );
16 # or use filehandles instead
18 $parser->parse_from_filehandle($in_fh, $out_fh);
19 # or get the XHTML as a scalar
21 my $parsertoo = new Pod::Xhtml( StringMode => 1 );
22 $parsertoo->parse_from_file( $infile, $outfile );
23 my $xhtml = $parsertoo->asString;
24 # or get a reference to the XHTML string
26 my $xhtmlref = $parsertoo->asStringRef;
27 # to parse some other pod file to another output file all you need to do is...
29 $parser->parse_from_file( $anotherinfile, $anotheroutfile );
30 There are options specific to Pod::Xhtml that you can pass in at
32 construction time, e.g.:
33 my $parser = new Pod::Xhtml(StringMode => 1, MakeIndex => 0);
35 See "OPTIONS". For more information also see Pod::Parser which this
37 module inherits from.
38
40 new Pod::Xhtml( [ OPTIONS ] )
41 Create a new object. Optionally pass in some options in the form
42 'new Pod::Xhtml( StringMode => 1);'
43 $parser->parse_from_file( INPUTFILE, [OUTPUTFILE] )
45 Read POD from the input file, output to the output file (or STDOUT
46 if no file is given). See Pod::Parser docs for more. Note that you
47 can parse multiple files with the same object. All your options
48 will be preserved, as will any text you added with the add*Text
49 methods.
50 $parser->parse_from_filehandle( [INPUTFILEHANDLE, [OUTPUTFILEHANDLE]] )
52 Read POD from the input filehandle, output to the output filehandle
53 (STDIN/STDOUT if no filehandle(s) given). See Pod::Parser docs for
54 more. Note that you can parse multiple files with the same object.
55 All your options will be preserved, as will any text you added with
56 the add*Text methods.
57 $parser->asString
59 Get the XHTML as a scalar. You'll probably want to use this with
60 the StringMode option.
61 $parser->asStringRef
63 As above, but you get a reference to the string, not the string
64 itself.
65 $parser->addHeadText( $text )
67 Inserts some text just before the closing head tag. For example you
68 can add a link to a stylesheet. May be called many times to add
69 lots of text. Note: you need to call this some time before any
70 output is done, e.g. straight after new(). Make sure that you only
71 insert valid XHTML fragments.
72 $parser->addBodyOpenText( $text ) / $parser->addBodyCloseText( $text )
74 Inserts some text right at the beginning (or ending) of the body
75 element. For example you can add a navigation header and footer.
76 May be called many times to add lots of text. Note: you need to
77 call this some time before any output is done, e.g. straight after
78 new(). Make sure that you only insert valid XHTML fragments.
79
81 StringMode
82 Default: 0. If set to 1 this does no output at all, even if
83 filenames/handles are supplied. Use asString or asStringRef to
84 access the text if you set this option.
85 MakeIndex
87 Default: 1. If set to 1 then an index of sections is created at the
88 top of the body. If set to 2 then the index includes non-bulleted
89 list items
90 MakeMeta
92 Default: 1. If set to 1 then some meta tags are created, recording
93 things like input file, description, etc.
94 FragmentOnly
96 Default: 0. If 1, we only produce an XHTML fragment (suitable for
97 use as a server-side include etc). There is no HEAD element nor any
98 BODY or HTML tags. Any text added with the add*Text methods will
99 not be output.
100 TopHeading
102 Allows you to set the starting heading level when in fragment mode.
103 For example, if your document already has h1 tags and you want the
104 generated POD to nest inside the outline, you can specify
105 TopHeading => 2
107 and "=head1" will be tagged with h2 tags, "=head3" with h3, and so
109 on.
110 Note that XHTML doesn't allow for heading tags past h6, so h7 and
112 up will be translated to h6 as necessary.
113 TopLinks
115 At each section head this text is added to provide a link back to
116 the top. Set to 0 or '' to inhibit links, or define your own.
117 Default: <p><a href="#TOP" class="toplink">Top</a></p>
119 LinkParser
121 An object that parses links in the POD document. By default, this
122 is a regular Pod::Hyperlink object. Any user-supplied link parser
123 must conform the the Pod::Hyperlink API.
124 This module works with a Pod::Hyperlink::BounceURL link parser and
126 generates hyperlinks as 'a' elements with a class of
127 'pod_xhtml_bounce_url'. The optional text giving the "node" is
128 enclosed in a 'strong' element with a class of
129 'pod_xhtml_bounce_url_text'
130
132 There's Pod::PXML and Pod::XML, so why do we need Pod::Xhtml? You need
133 an XSLT to transform XML into XHTML and many people don't have the time
134 or inclination to do this. But they want to make sure that the pages
135 they put on their web site are well-formed, they want those pages to
136 use stylesheets easily, and possibly they want to squirt the XHTML
137 through some kind of filter for more processing.
138 By generating well-formed XHTML straight away we allow anyone to just
140 use the output files as-is. For those who want to use XML tools or
141 transformations they can use the XHTML as a source, because it's a
142 well-formed XML document.
143
145 This module outputs well-formed XHTML if the POD is well-formed. To
146 check this you can use something like:
147 use Pod::Checker;
149 my $syn = podchecker($defaultIn);
150 If $syn is 0 there are no syntax errors. If it's -1 then no POD was
152 found. Any positive number indicates that that number of errors were
153 found. If the input POD has errors then the output XHTML should be
154 well-formed but will probably omit information, and in addition
155 Pod::Xhtml will emit warnings. Note that Pod::Parser seems to be
156 sensitive to the current setting of $/ so ensure it's the end-of-line
157 character when the parsing is done.
