document: A fast XPATH evaluation technique with the facility of updates This paper addresses the problem of fast retrieval of data from XML documents by providing a labeling schema that can easily handle simple as well as complex XPATH queries and also provide for updates without the need for the entire document being re-indexed in the RDBMS . We introduce a new labeling schema called the `` Z-Label '' for efficiently processing XPATH queries involving child and descendant axes . The use of `` Z-Label '' coupled with the indexing schema provides for smooth updates in the XML document .
