Project Outline and Aims

As the use of XML on the Web has become more widespread, there is an associated need to transform XML in various ways to meet differing requirements. Most such transformations are performed using either XSLT or XQuery, both of which use XPath for the selection of elements.

Where transformations or queries are complicated or are to be performed on large documents, there is a need to optimise XPath expressions in order to rewrite them into more efficient forms. This project investigates

Collectively, our papers on minimising XPath expressions and containment of XPath expressions have received over 200 citations according to Google scholar.

Funding and Staffing Details

The project is being undertaken by Peter Wood and Manizheh Montazerian, who is working in the area for her PhD.
