An Indexing Method for Supporting Structure Queries on XML Documents

Abstract

Much research has been carried out to manage structured documents such as SGML (Standard Generalized Markup Language) or XML (eXtensible Markup Language) documents and to provide powerful query facilities exploiting document content, structure, and attributes. In order to perform structure queries efficiently on structured documents, a good indexing method for structured documents is important and necessary. In this paper, we present an indexing method which is utilized for supporting efficient query on content, structure and attributes on XML documents. Furthermore, we propose some strategies of update method to maintain the integration of changed index information and original XML documents.
