E.g. Lark's symbol table is a double array, storing both the character-array and String version of each name - you lookup based on the character array and return the string if it's already there. The point is that you call new String() only once per unique name. -Tim xml-dev: A list for W3C XML Developers. To post, mailto:xml-dev@i...
