The number of documents published via WWW in form of SGML/HTML has been rapidly growing for years. Efficient, declarative access mechanisms for this type of documents - structured documents in general - are becoming of great importance. This paper reports our most recent advance in pursuit of effective processing and optimization of structured-document queries, which are important for large repositories of structured documents. Our methodology emphasizes applying exclusively deterministic transformations on query expressions to achieve the best possible optimization efficiency. A new approach is thus proposed that facilitates the exploitation of the DTD-knowledge, structural properties, and structure indices of structured documents for the purpose of fast query optimization.
