SYNOPSIS

11        $html    = 'Hi Honey<b>&hearts;</b>';
12
13        # convert named HTML entities to numbered (decimal)
14        $decimal = name2decimal($html);    # Hi Honey<b>&#9829;</b>
15
16        # to numbered (hexadecimal)
17        $hex     = name2hex($html);        # Hi Honey<b>&#x2665;</b>
18
19        $content = 'Copyright &#169; Larry Wall';
20
21        # convert numbered HTML entities (decimal) to named
22        $name1   = decimal2name($content); # Copyright &copy; Larry Wall
23
24        $content = 'Copyright &#xA9; Larry Wall';
25        # convert numbered HTML entitites (hexadecimal) to named

DESCRIPTION

40       HTML::Entities::Numbered is a content conversion filter for named HTML
41       entities (symbols, mathmetical symbols, Greek letters, Latin letters,
42       etc.).  When an argument of "name2decimal()" or "name2hex()" contains
43       some nameable HTML entities, they will be replaced to numbered HTML
44       entities. And when an argument of "name2decimal_xml()" or
45       "name2hex_xml()" contains some nameable numbered HTML entities, they
46       will be replaced to numbered HTML entities except valid XML entities
47       (the excepted "valid XML entities" are the following five entities:
48       "&lt;", "&gt;", "&amp;", "&quot;", "&apos;").  By the same token, when
49       an argument of "decimal2name()" or "hex2name()" contains some nameable
50       numbered HTML entities, they will be replaced to named HTML entities.
51
52       (the exception "valid XML entities" means the following five entities:
53       "&lt;", "&gt;", "&amp;", "&quot;", "&apos;")
54
55       On version 0.03, the entities hash table is imported from
56       HTML::Entities (with obsolete class "HTML::Entities::Numbered::Extra"
57       for older releases of Perl).  At the moment, 0.04 (or later) is
58       included HTML::Entities::Numbered::Table to import HTML entities table,
59       and thereby we do not need to have HTML::Entities (included in
60       HTML::Parser distribution).
61
62       This may be also useful for making valid XML (corrects the undefined
63       entity references, and enhanced by addition of functions conform to the
64       XML).

91       ·   name2decimal_xml
92
93           Some included named HTML entities in argument of

96
97       ·   name2hex_xml
98
99           Some included named HTML entities in argument of "name2hex_xml()"
100           will be replaced to hexadecimal numbered HTML entities except valid
101           XML entities.
102
103       If you'd prefer not to import them functions into the caller's
104       namespace, you can call them as below:
105
106        use HTML::Entities::Numbered ();
107
108        $decimal = HTML::Entities::Numbered::name2decimal($str);
109        $hex     = HTML::Entities::Numbered::name2hex($str);
110        $named1  = HTML::Entities::Numbered::decimal2name($str);
111        $named2  = HTML::Entities::Numbered::hex2name($str);
112        $decimal = HTML::Entities::Numbered::name2decimal_xml($str);
113        $hex     = HTML::Entities::Numbered::name2hex_xml($str);
