XPath 2.0: It Can Sort!
نویسنده
چکیده
As XML finds its place in information technology, query languages for XML attract much attention. Among them XPath is the most known. This article reveals a surprising fact that the upcoming XPath 2.0 is capable of sorting sequences, which is proved formally. We also mark out an incompleteness of XQuery Core and an insufficiency of definition of XQuery Core sorting semantics. The fact that XPath 2.0 can sort arbitrary sequences is used to fix it.

Introduction to Xquery *
XQuery is a query language for data stored in xml form. It can be used to search such documents and arrange the result, as an xml structure or a simple text (possibly suitable for a TEX engine). Like xslt 2.0, it is based on XPath 2.0. We propose an introduction to XQuery, and some comparisons with xslt allow readers to discern the applications XQuery is suitable for.

This paper is about the W3C standard node-addressing language for XML documents, called XPath. XPath is still under development. Version 2.0 appeared in 2001 while the theoretical foundations of Version 1.0 (dating from 1998) are still being widely studied. The paper aims at bringing XPath to a “stable fixed point” in its development: a version which is expressively complete, still manageable c...

The conclusion is that, although it provides some mechanisms to assign resources to busi...
