Recently, XML has become a standard for data representation, manipulation and exchange on the web. The increase in the use of XML in many applicative domains induces a strong need for providing XML query capabilities to many users. In this paper, we propose a solution of XML graphical querying based on the XQuery language. In our approach, we propose to integrate textual, spatial and temporal meta-data in order to improve information retrieve and present document suitable to the user’s needs. We, also, propose the extension of the XQuery by new operators in XQuery grammar to facilitate the use of the meta-documents. 1.
