HTML::Entities - Encode or decode strings with HTML entities
use HTML::Entities;
$a = "Våre norske tegn bør æres";
decode_entities($a);
encode_entities($a, "\200-\377");
This module deals with encoding and decoding of strings with HTML
character entities. The module provides the following functions:
decode_entities($string)
-
This routine replaces HTML entities found in the $string with the
corresponding ISO-8859/1 (or with perl-5.7 or better Unicode)
character. Unrecognized entities are left alone.
- encode_entities($string, [$unsafe_chars])
-
This routine replaces unsafe characters in $string with their entity
representation. A second argument can be given to specify which
characters to concider as unsafe. The default set of characters to
expand are control chars, high-bit chars and the '<', '&', '>' and '``'
characters.
Both routines modify the string passed as the first argument if
called in a void context. In scalar and array contexts the encoded or
decoded string is returned (and the argument string is left
unchanged).
If you prefer not to import these routines into your namespace you can
call them as:
use HTML::Entities ();
$encoded = HTML::Entities::encode($a);
$decoded = HTML::Entities::decode($a);
The module can also export the %char2entity and the %entity2char
hashes which contain the mapping from all characters to the
corresponding entities.
