Querying XML documents with temporal variables
Xiao-Ping Ye, Yong Tang, Zhaomei Huang, Yiquan Jiang · 2005
In this paper, we analyze the characteristic between temporal relation and XML-document according to temporal queries, and discuss some problems about XML queries which contain two temporal variables, denoted by "NOW" and "uc". We also show solutions for these problems. In finally, we validate our algorithms in practice using XQuery, a powerful query language designed for XML.
