We propose XPathMark, an XPath benchmark on top of the XMark generated data. It consists of a set of queries which covers the main aspects of the language XPath 1.0. These queries have been designed for XML documents generated under XMark, a popular benchmark for XML data management. We suggest a methodology to evaluate the XPathMark on a given XML engine and, by way of example, we evaluate two popular XML engines using the proposed benchmark.
