Abstract
Described herein are techniques that allow applications developed in non-object oriented languages, such as C, to interact with DOM trees implemented under different DOM implementations. An application accesses different DOM implementations through a set of function pointers that conform to a set of function signatures. The set of function pointers may be stored in a data structure defined to have member function pointers that point to functions that conform to the set of function signatures. The set of function signatures define a common interface through which applications may interact with a variety of DOM implementations. One or more applications generate the set of function pointers and store them in a data structure. The other applications register the function pointers with an application by, for example, passing a pointer to the data structure to the application.
