NAME

MathML::Entities - Convert XHTML+MathML Named Entities to Numeric Character References

SYNOPSIS

 use MathML::Entities;
 
 $html    = '<b>&copy;</b> by me';
 
 # convert named HTML entities to character references:
 $numeric = name2numbered($html);    # <b>&#x000A9;</b> by me

 # convert named HTML entities to character references:
 $utf8 = name2utf8($html);    # utf8 
 

DESCRIPTION

MathML::Entities a content conversion filter for named XHTML+MathML entities. There are over two thousand named entities in the XHTML+MathML DTD. All the Entities defined in the XHTML+MathML DTD except the five "safe" ones (<, >, &, ", '), will be converted to the equivalent numeric character references or to utf-8 characters. Named entities which are not in the XHTML+MathML DTD are escaped. This makes the resulting XHTML (or XHTML+MathML) safe for consumption by non-validating XML parsers.

Unlike, HTML::Entities, the mapping between MathML named entities and codepoints is many-to-one. Therefore, there's no particular sense in having an inverse function, which takes codepoints to named entities.

Based on: HTML::Entities by Koichi Taniguchi <taniguchi@livedoor.jp>

FUNCTIONS

The following functions are exported by default.

• name2numbered

  XHTML+MathML named entities (except for the five "safe" XML named entities) in the argument of name2numbered() are replaced by the corresponding numbered character references.

• name2utf8

  XHTML+MathML named entities (except for the five "safe" XML named entities) in the argument of name2utf8() are replaced by the corresponding utf-8 characters.
