The source uses the example of yesterday to load book. xml into the collection named novel in the books database.
Query the content:
se_term -query "for $p in collection('novel')/books return $p" books
In Windows, the result is as follows:
D:\sedna\bin>se_term -query "for $p in collection('novel')/books return $p" books

In Oracle's 10g 2nd edition, Oracle introduced a full-featured, self-contained XQuery engine integrated with the database that can be used to complete various tasks related to developing XML-enabled applications. XQuery is a query language for processing XML data models, which can actually manipulate data of any type that can be expressed in XML. Although Oracle
XQuery brings a lot of hope to software architects and developers because it dramatically reduces the amount of code that needs to be written to create a service that uses XML. You might think that what XQuery is doing is easy to understand, but there are still misconceptions and misconceptions in the XQuery software development community. Frank Cohen analyzes an
1. Robot uses a professional testing script language, which leads to the need to learn specialized APIs and specialized syntaxes. In addition, procedural Visual Basic is used as the script language, which limits script reuse.
2. The coupling between the robot and the test management tool is too tight. The script cannot be well managed, nor can it be flexibly tested and executed.
3. Robot cannot be integrated with IDE, so developers do not want to learn it. testing automation technology is not on
XSLT and XPath to accomplish this task. XPath is a syntax for accessing only parts of an XML document that meet a certain criteria; XSLT is a technology that transforms an XML document from one form to another.
While XSLT and XPath have been in use for a while now, there is a new kid on the block: XML query, or XQuery for short. XQuery is a querying language designed specifically to work with XML data stor
The DB2 tutorial is: Query DB2 XML data using XQuery.
About XQueryXQuery differs from SQL in many key aspects, largely because these two languages are designed for two data models with different characteristics. XML documents contain hierarchies and have an inherent order. The SQL-based database management system supports flat and set-based table data structures. Therefore, there is no order between rows.
The two data models have different query la
I've brought a number of development teams and test teams to talk about the good testers I have in mind. I hope it will help you in your future career.

How is your work attitude, is to evaluate a tester's most important aspect, a high level tester (refers to pure technical ability) without a good working attitude, in the Test team sometimes not only can not play a role in the test work, and sometimes hinder, and a willing to work
At present, many open-source organizations and companies have implemented query Engines Based on the XQuery reference standards. The Representative open-source XQuery engines are XQEngine, Saxon, Galax, and other open-source XQuery engines, dataDirect company's DataDirect Xquery.

This dead program has been a year since the end of the year, and has been resting for too long in the middle of the New Year. The result is as if it were done twice. For the first time, the document structure of MFC was used in the regular expression tester. In fact, this small program is getting bigger and bigger, and the function is actually a little more.
The current version is using boost. the RegEx library has basically completed the function of
The best way to explain XQuery is to say that the relationship between XQuery and XML is equivalent to the relationship between SQL and database tables.
XQuery is designed to query XML data-not only for XML files, but also for any data that can be presented in XML format, including databases.What is XQuery?
Note: This article was revised in December 2005 to incorporate the latest changes in the XQuery specification: eight of these work drafts have entered the "candidate recommendation for the World wide Business" status, and the overall specification distance is a step closer to the "Recommended standard". The main Full-text document was originally published in 2004 and has recently been modified. The "Draft requirements work (Requirements Working Draft)
You may have heard of the new DB2 Viper architecture, which supports table and hierarchical data structures. In fact, the previous article summarized the New XML features in DB2 and described how to create database objects and populate these database objects with XML data, it explains how to use SQL and SQL/XML to operate XML data. This article continues to explore the DB2 XML feature. This time, we will focus on DB2's new support for XQuery.
DB2 uses
XML (extensible Markup Language Extensible Markup Language) The self-describing nature of data makes it highly structured, has a good storage format, and XML documents are as easy to network transfer as HTML. As a result, XML is widely used as a key criterion for data definition, data exchange and data sharing.
At present, the main research direction of XML database is divided into two parts, one is native XML database system, also known as native or pure XML database, such as Tamino, Ipedo and

XML involves a series of technical specifications and related technologies, with many and complex concepts. Here, we will briefly introduce four concepts: XPath, XSLT, XQuery, and xqueryx, which are W3C specifications.
XPath is the XML Path Language. XPath provides general syntax and semantics for locating and linking information in an XML document. It is an expression language that can be used to easily identify nodes in XML documents. XPath is de
DB29 introduced pureXML support, which means that XML data is stored and queried in its inherent hierarchical format. To query XML data, DB2 provides two languages: SQLXML and XQuery.
