Abstract
A method of pre-processing an XQuery on a XML data base and may comprise parsing the XQuery to obtain an abstract syntax tree and typing the abstract syntax tree to provide at least one pointer into a schema for XML documents of the XML data base. The typing step may involve the use of schema and accumulated instance data of the XML data base. Use of the accumulated instance data in addition to schema data allows for reduction of the set of pointers to a smaller set, which in turn reduces the number of documents to be examined when the query is executed.
