I've seen Javascript being used to write Javascript before because it required less (albeit uglier) code than using cross-browser code to add event handlers. The parser could though maybe split off strings it finds within Javascript like this and parse that with the same function. It could potentially then call itself recursively each time it encounters a string. Thanks, Ash http://www.ashleysheridan.co.uk
