type Name = String

list :: [(Name, Char)]

A table mapping XML entity names to code points. Although entity references can in principle represent more than one character, the standard entities only contain one character.

listInternetExploder :: [(Name, Char)]

This list excludes apos as Internet Explorer does not know about it.

mapNameToChar :: Map Name Char

mapCharToName :: Map Char Name

numberToChar :: String -> Exceptional String Char

Lookup a numeric entity, the leading '#' must have already been removed.

numberToChar "65" == Success 'A'
numberToChar "x41" == Success 'A'
numberToChar "x4E" === Success 'N'
numberToChar "x4e" === Success 'N'
numberToChar "Haskell" == Exception "..."
numberToChar "" == Exception "..."
numberToChar "89439085908539082" == Exception "..."

It's safe to use that for arbitrary big number strings, since we abort parsing as soon as possible.

numberToChar (repeat '1') == Exception "..."
