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

use MathML::Entities; $html = '<b>©</b> by me'; # convert named HTML entities to character references: $numeric = name2numbered($html); # <b>©</b> by me # convert named HTML entities to character references: $utf8 = name2utf8($html); # utf8

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>

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.
