        the value of the entity or null
      • expand

        public String expand​(String entity)
        Expand an entity reference. If the reference is unknown, the method will null.

        Valid inputs are entity names or entity references (i.e. it will work with "lt" and "<")

      • encode

        public String encode​(String input)
        Replace text in a string with entity references
      • expandNumericEntity

        public int expandNumericEntity​(String entity)
        Returns the character value of a numeric entity.

        NOTE: This method returns a "code point", not a character. One "code point" can map to one or two Java characters!

        Throws:
        IllegalArgumentException - if the numeric entity has the wrong format, or the value is too low or high.
