5
FLWOR ( "flower" ) is often mentioned in the context of XQuery.
FLWOR（“flower”）经常会在XQuery上下文中提到。
6
XQuery uses a concise set of commands to make it easy to work with XML data.
XQuery使用一组简洁的命令，很容易处理XML。
7
Additionally, the existential nature of the XQuery general comparison predicates requires attention when you express a "between" condition.
另外，当表达“between”条件时，需要注意XQuery一般比较谓词的存在本质。
8
It is often used outside of any relational databases to query XML data, which may be stored in text files.
XQuery常用于在关系数据库外查询XML数据，这些数据可能存储在文本文件中。
9
For advanced XML users, XQuery can be very helpful in querying and extracting content out of large XML documents.
对于高级XML用户，XQuery在查询和从大型XML文档抽取内容时非常有帮助。
10
For the moment, most native XML databases fill this hole in various, proprietary ways, often implemented as an XQuery extension.
目前来说，多数原生XML数据库都以各种不同的、专有的方式填补了这一漏洞，通常作为XQuery的扩展实现。
11
This fluidity makes XQuery just as appropriate as a database search system as it is to queue filtering.
这种可塑性使XQuery不仅适合作为数据库搜索引擎，还可用于队列筛选。
12
From a development costs perspective, the XQuery approach turned out to be a significant savings.
从开发成本角度看，XQuery方法已证实可以节约大量成本。
13
Plain XQuery does not allow you to call SQL user defined functions (UDFs) or external UDFs written in C or Java.
普通XQuery不允许您调用SQL用户定义的函数（UDF）或者用C语言或Java编写的外部UDF。
14
The next example filters the set of input documents to XQuery by joining with a nickname.
下一个示例通过与昵称连接过滤一组到XQuery的输入文档。
15
An XPath statement in an XQuery or XSLT stylesheet might test for one of the predefined elements and also display the known color.
XQuery或XSLT样式表中的一个XPath语句可能测试一个预定义元素并显示已知颜色。
16
XQuery allows a client to describe precisely the type of XML document that it would like the server to return.
XQuery允许客户端精确描述希望服务器返回的XML文档类型。
17
As you might imagine, the XQuery where clause enables you to filter results based on the value of the zip element in your XML documents.
与您想像的一样，通过XQuerywhere子句可以根据XML文档中zip元素的值来过滤结果。
18
At the end of this tutorial, you will have a working example of an XQuery function and its applicability to a business requirement.
在教程的末尾，您将拥有自己的XQuery函数示例，它能够正常工作并且可以满足业务需求。
19
Added to the list of requirements for a view that direct references to Xquery expressions are not allowed in an indexed view definition.
在视图的要求列表中添加了在索引视图定义中不允许使用对Xquery表达式的直接引用的说明。
20
Using SQL group by and aggregation functions on that table is usually more efficient than producing the same result in plain XQuery.
对该表使用SQL的groupby函数和聚集函数通常比使用生成相同结果的普通XQuery更有效。
21
For each purchase order an XQuery is executed that returns a formatted result of each product subtotal.
对于每个采购订单，都将执行一个XQuery，返回每个产品小计的格式化结果。
22
XQuery is good for XML-only applications that do not need (or do not wish) to use SQL or relational structures.
对于仅涉及XML、不需要（或不希望）使用SQL或关系结构的应用程序来说，XQuery很适用。
23
XQuery looks like SQL and solves many of the SQL problems that cause me to run back to my bookshelf for answers.

25
I'll show you a few quick XQuery expressions to give you a flavor of what XQuery can do, and then move on to the screen-scraping examples.
然后我们将介绍一些快速的XQuery表达式，让您对XQuery能够做什么形成一种认识，最后我们将再转到屏幕搜集的示例上。
