SgmlQL + XGQL = Powerful XML Pattern-Matching and Data-Manipulation in a Single Language

The presence of XML in many recent hypermedia management tools and methods (W3I3, SMIL, etc.) shows better than ever that both structural and textual criteria will continue to play a fundamental role in content-based multimedia retrieval and management. Extracting precise and fine-grained information from structured documents requires powerful pattern-matching. Most existing XML query languages are fairly limited in this respect. Powerful pattern-matching languages do exist, but usually lack the data manipulation capabilities required of a true information management environment. In this paper, we investigate how XGQL, a powerful pattern-matching language based on generalized grammars, can be integrated into SgmlQL, a complete XML retrieval and manipulation language.
