Omar - also keep in mind all the solutions you are seeing make the assumption that the xml object is global to the context, there are many situations where you only want the xml instance to be around for a short time and keeping it within function scope and then passing a node around or the parsed version of it around - then you should pass the xml object to your function, otherwise if you keep it as a class member (or global) - then all is well.
While I'm not 100% sure, I don't think you can make the xml object within a function scope and still use the delegate in this fashion. In that case, you'd need to assign the delegate.create the xml object as the context, with the function being a class member function. But of course the problem with that would be you wouldn't have access to your other class members when the function was called. Unless someone knows of another way - only the AS1 version will allow you to encapsulate the xml object (without having it as a class member or global). Just a few more notes, hope all of it is helpful.
