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 entites. The module provide the following functions:
This routine replaces HTML entities found in the $string with the corresponding ISO-8859/1 character. Unrecognized entities are left alone.
- endode_entities($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 '"' character.
Both routines modify the string passed in as the first argument if called in void context. In scalar and array context 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 contains the mapping from all characters to the corresponding entities.
