XML-based communication is e ective, because it is programmer-friendly and has great exibility. It is widely spread on variety of platforms. However, penetration of this technology has not yet reached embedded devices, because parsing of textual messages has usually large overhead and is demanding on resources. The goal of this work is to devise, implement and test a new method of parsing SOAP messages involving formal grammars and automata, thus allowing the use of web services to expand also to small devices, even on the ones without OS support. Our solution is called EXCUSA - acronym for "E ective XML Communication Using SOAP and Automata". |
