XPath query processing improvements
P. Mark Pettovello, Farshad A. Fotouhi · 2010
Much research has been done adapting relational technology for use with XML and XPath query processing, several research efforts have focused on native XML databases, and some research efforts have focused on hybrid approaches. This paper presents a hybrid design: we extend the usage of path summary indexes by combining them with partitioned indexes on schema-less XML documents to accelerate XPath query processing. Efficient XPath query processing is important because XPath is the query language used for node selection within XQuery.
