A New Method for Querying XML Data

Abstract
Extensible Mark-up Language (XML) is currently an important standard method for formatting and exchanging data over the Internet. Updating and retrieving a massive amount of XML data is an interesting and active research area. In addition, indexing XML data is an important task to improve the efficiency of XML queries. Therefore, this paper surveys the methods that used for indexing XML data. Subsequently, a new approach is proposed for indexing and querying XML data efficiently. In addition, this approach used the idea of dividing the nodes of an XML document into groups and labelling them accordingly. Two existing labelling schemes were selected carefully for labelling these groups and their nodes in order to improve the efficiency of the XML query.
