Abstract
As many metadata are encoded in XML, and many digital libraries need to manage XML documents, efficient techniques for searching in such formatted data are required. In order to efficiently process path expressions with wildcards on XML data, a new path index is proposed. Extensive evaluation confirms better performance with respect to other techniques proposed in the literature. An extension of the proposed technique to deal with the content of XML documents in addition to their structure is also discussed.File in questo prodotto:
