Efficient XPath evaluation

Abstract

Inspired by the best querying performance of ViST among the rest of the approaches in the literature, and meanwhile to overcome its shortcomings, in this paper, we present another efficient and novel geometric sequence mechanism, which transforms XML documents and XPath queries into the corresponding geometric data/query sequences. XML querying is thus converted to finding non-contiguous geometric subsequence matches. Our approach ensures correct (i.e., without semantic false) and fast (i.e., without the costly post-processing phase) evaluation of XPath queries, while at the same time guaranteeing the linear space complexity. We demonstrate the significant performance improvement of our approach through a set of experiments on both synthetic and real-life data.
