  1. We first present a number of desiderata for an xml - based query language, and based on this criterion, we introduce the syntax of a simple core ian - guage for semistructured data and then describe four extensions that have resulted in working prototypes. second, we present the algorithm for computing the result of a regular expression on data graph with cycles, the first - order interpretation of querying language for semistructured data, and explore structural recursion and bisimulation in semistructured data and propose an efficient and systematic way to computing a bisimulation between the two graphs. we also proposed and implemented a web querying system with database features
