Abstract

XML is a versatile markup language, capable of labeling the information content of diverse data sources including structured and semi-structured documents, relational databases, and object repositories. A query language that uses the structure of XML intelligently can express queries across all these kinds of data, whether physically stored in XML or viewed as XML via middleware. This specification describes a query language called XQuery, which is designed to be broadly applicable across many types of XML data sources.

[edit]

摘要

XML是一种通用标记语言，它能对各种数据源的信息内容进行标记，包括结构化和半结构化文档、关系数据库和对象库。一种智能地使用XML结构的查询语言能够表达所有这些类型数据之间的查询，不管它们是物理存储在XML中还是通过中间件被视为XML。本规范描述了一个称为XQuery的查询语言，它被设计为能广泛应用于很多类型的XML数据源之间。

This section describes the status of this document at the time of its publication. Other documents may supersede this document. A list of current W3C publications and the latest revision of this technical report can be found in the W3C technical reports index (http://www.w3.org/TR/) at http://www.w3.org/TR/.
这一节描述了本文档在发布时的状态。本文档可能被其他文档代替。W3C的发布的当前文档列表和本技术报告的最新修改可以在http://www.w3.org/TR/ 的W3C 技术报告索引 (http://www.w3.org/TR/)找到。
This is a public W3C Working Draft for review by W3C Members and other interested parties. Publication as a Working Draft does not imply endorsement by the W3C Membership. This is a draft document and may be updated, replaced or obsoleted by other documents at any time. It is inappropriate to cite this document as other than work in progress.
这是一个公开的W3C工作草案以供W3C成员和其它感兴趣的团体审阅。作为一个工作草案发布不意味着受到W3C成员资格的认可。这是一个草案文档，它可能在任何时候被其它文档更新、取代或者作废 。除了正在进行的工作外，引用这个文档是不合适的。
XQuery 1.0 has been defined jointly by the XML Query Working Group (http://www.w3.org/XML/Query) and the XSL Working Group (http://www.w3.org/Style/XSL/) (both part of the XML Activity (http://www.w3.org/XML/Activity.html)). The XPath 2.0 and XQuery 1.0 Working Drafts are generated from a common source. These languages are closely related, sharing much of the same expression syntax and semantics, and much of the text found in the two Working Drafts is identical.
XQuery 1.0是由XML Query工作组 (http://www.w3.org/XML/Query)（XML Query Working Group ）和XSL工作组 (http://www.w3.org/Style/XSL/)（XSL Working Group）（二者都是XML活动组 (http://www.w3.org/XML/Activity.html)（XML Activity)）的一部分）联合定义的。XPath 2.0和XQuery 1.0工作草案是由同一个源头产生的。这两种语言紧密相连，共用很多相同的表达式语法和语义，而且两个工作草案中的很多文本是一模一样的。
This working draft includes a number of changes made in response to comments received during the Last Call period that ended on Feb. 15, 2004. The working group is continuing to process these comments, and additional changes are expected. A list of changes introduced by this draft can be found in I Revision Log.
这个工作草案包括了很多修改，这些修改是对于2004年2月15日截止的最后征求意见（Last Call ）阶段收到的建议的响应。工作组正在继续处理这些建议，预计还会有进一步的修改。这个草案作出的修改清单可以在I 更正日志中找到。
This document reflects decisions taken up to and including the face-to-face meeting in Cambridge, MA during the week of June 21, 2004. These decisions are recorded in the Last Call issues list (http://www.w3.org/2004/07/xquery-issues.html) (http://www.w3.org/2004/07/xquery-issues.html). However, some of these decisions may not yet have been made in this document.
本文档反映了被采纳的决议，其中包括2004年7月21日那一周在Cambridge, MA的面对面会议。这些决议记录在最后征求意见问题清单 (http://www.w3.org/2004/07/xquery-issues.html)(http://www.w3.org/2004/07/xquery-issues.html) 里。但是，这些决议中的某些部分可能并没有在本文档中体现出来。
Public comments on this document and its open issues are invited. Comments should be sent to the W3C XPath/XQuery mailing list, public-qt-comments@w3.org (mailto:public-qt-comments@w3.org) (archived at http://lists.w3.org/Archives/Public/public-qt-comments/ (http://lists.w3.org/Archives/Public/public-qt-comments/)), with “[XQuery]” at the beginning of the subject field.
欢迎对对本文档及其悬而未决的问题给出公开建议。建议请发到W3C XPath/XQuery邮件列表，public-qt-comments@w3.org (mailto:public-qt-comments@w3.org)（存档在http://lists.w3.org/Archives/Public/public-qt-comments/ (http://lists.w3.org/Archives/Public/public-qt-comments/)），题目栏请以"[XQuery]"开头。
The patent policy for this document is expected to become the 5 February 2004 W3C Patent Policy (http://www.w3.org/Consortium/Patent-Policy-20040205/), pending the Advisory Committee review of the renewal of the XML Query Working Group. Patent disclosures relevant to this specification may be found on the XML Query Working Group's patent disclosure page (http://www.w3.org/2002/08/xmlquery-IPR-statements) and the XSL Working Group's patent disclosure page (http://www.w3.org/Style/XSL/Disclosures). An individual who has actual knowledge of a patent which the individual believes contains Essential Claim(s) with respect to this specification should disclose the information in accordance with section 6 of the W3C Patent Policy (http://www.w3.org/Consortium/Patent-Policy-20040205/#sec-Disclosure).
本文档的专利条例有望是2004年2月5日的W3C专利条例，它使得咨询委员会（Advisory Committee）对XML Query工作组的更新的审查悬而未决。与本规范相关的已公开的专利可以在Query工作组的专利公开页面 (http://www.w3.org/2002/08/xmlquery-IPR-statementsXML)（XML Query Working Group's patent disclosure page）和XSL工作组的专利公开页面 (http://www.w3.org/Style/XSL/Disclosures)（XSL Working Group's patent disclosure page）上找到。如果有人知道一种专利包含了与本规范相关的实质声明（Essential Claim(s) ），请按照W3C专利条例 (http://www.w3.org/Consortium/Patent-Policy-20040205/#sec-Disclosure)的第6节进行公开。
