International Journal of Web Science (IJWS), Vol. 2, No. 4, 2014

Abstract: The increasing number of XML documents over the internet motivated us to develop indexing techniques to retrieve the XML data efficiently. Assigning unique labels to each node and determining the structural relationships is a critical problem in XML query processing. Labelling schemes designed for static XML documents will not support dynamic updates on XML documents. Some dynamic labelling schemes provide dynamic updates but, with a high cost and complexity. In this paper we propose a labelling scheme which supports the dynamic update without relabelling the existing nodes. It also determines the structural relationships efficiently by looking at the labels. A set of performance tests is carried to compute the time required to generate unique labels.
