lookupEntity :: String -> Maybe String Source #
Lookup an entity, using lookupNumericEntity
if it starts with
#
and lookupNamedEntity
otherwise
lookupNamedEntity :: String -> Maybe String Source #
Lookup a named entity, using htmlEntities
lookupNamedEntity "amp" == Just "&" lookupNamedEntity "haskell" == Nothing
lookupNumericEntity :: String -> Maybe String Source #
Lookup a numeric entity, the leading '#'
must have already been removed.
lookupNumericEntity "65" == Just "A" lookupNumericEntity "x41" == Just "A" lookupNumericEntity "x4E" === Just "N" lookupNumericEntity "x4e" === Just "N" lookupNumericEntity "X4e" === Just "N" lookupNumericEntity "Haskell" == Nothing lookupNumericEntity "" == Nothing lookupNumericEntity "89439085908539082" == Nothing
escapeXML :: String -> String Source #
Escape an XML string.
escapeXML "hello world" == "hello world" escapeXML "hello & world" == "hello & world"
xmlEntities :: [(String, String)] Source #
A table mapping XML entity names to resolved strings. All strings are a single character long.
Does not include apos
as Internet Explorer does not know about it.
htmlEntities :: [(String, String)] Source #
A table mapping HTML entity names to resolved strings. Most resolved strings are a single character long,
but some (e.g. "ngeqq"
) are two characters long. The list is taken from
http://www.w3.org/TR/html5/syntax.html#named-character-references.
