Abstract
With the growing popularity of XML and emer-
gence of streaming data model, processing queries
over streaming XML has become an important
topic. This paper presents a new framework and
a set of techniques for processing XQuery over
streaming data. As compared to the existing work
on supporting XPath/XQuery over data streams,
we make the following three contributions:
1. We propose a series of optimizations which
transform XQuery queries so that they can be cor-
rectly executed with a single pass on the dataset.
2. We present a methodology for determining
when an XQuery query, possibly after the trans-
formations we introduce, can be correctly exe-
cuted with only a single pass on the dataset.
