As XML seems to become the preferred candidate language for the interchange of data on the Internet, the integration of distributed, heterogeneous, and autonomous XML data sources in a mediation architecture is becoming a critical issue. In this paper, We present a novel and original query rewriting algorithm for the answering of queries to XML disparate sources in the presence of XML keys. The algorithm combines features of the MiniCon (Mini- Con descriptions) and the Styx algorithms (prefix and suffix queries) into an algorithm that returns more rewritings.
