You can simplify this to:


    import Control.Applicative hiding ((<|>))

    gettext = Body <$> many1 (noneOf "><")


And some of your other parsers can be simplified as well:

    innerXML = xml <|> gettext

    openTag :: Parser String
    openTag = char '<' *> many (noneOf ">") <* char '>'

    endTag :: String -> Parser String
    endTag str = string "</" *> string str <* char '>'
