This paper describes the design and implementation of an XML storage manager for fast and interactive XPath expressions evaluation. This storage manager has two main parts: the XML data storage structure and the index over this data. The system is designed in such a way that it minimizes the number of page reads for retrieving any XPath expression results while avoiding the shortcomings of previous work on storing XML data where the index must adapt to the most frequent queries. Hence, the main advantage of our index is that it can handle any new XPath expression without any need for adaptation. We show comparable performance of our design by presenting path evaluation results of our index against those of the currently most known index on documents of different sizes.
