请各位大侠能帮我翻译一下吗？谢谢啦

XML documents are at home in a wide range of processes. The phrase post-processing was practically tailor-made for XML; it means taking information from a document and using it in some other process or program. For example, suppose you receive a purchase order in the form of an XML document. An application that understands XML purchase orders can use that data to determine which items (and in what quantities) have been ordered — and can even send instructions to another piece of software to generate a pick list so the order can be picked, packed, and shipped from the warehouse.

In many cases, XML documents are used with stylesheets to provide high-quality output on-screen. You can use the same data, however, to send information to a speech-synthesis program that reads the text to a person who is vision impaired. Alternatively, that same data might also create output on a Braille reader. The same document with a layout program and a stylesheet also might be used for high-quality printouts.

The beauty of this concept is that you never need to fuss and fidget with the XML data to create output for different devices. You need only use different pieces of software that can read XML and can provide the output for a particular format or output device.
Using the same data across platforms

The good news looks, at first, like no news: XML documents are not specific to any particular platform or programming language. Okay, why is that something to e-mail home about? Think versatility. Suppose you want to exchange database information across the Web — say, use a Web browser to send information from a user questionnaire back to a Web server. To accomplish this task (and many others), you need a document format that is

1. Extensible: An extensible format is one that can be tailored or customized for specific applications.
2. Open: It's well documented and widely available.
3. Nonproprietary: It's expressed in an accepted or standard form of notation that isn't the exclusive property of some individual, company, or organization.
These characteristics enable the document to adapt to changing conditions, to take best advantage of the work of others, and to avoid incurring extra expense or legal liability.
Guess what? XML meets all three requirements for a document format for exchanging data — it's open, extensible, and nonproprietary. No surprise, then, that XML is the best choice for data exchange; those three magic characteristics make it a handy, consistent way to hand data around among multiple applications and multiple platforms with the most efficiency and least hassle.
Enforcing rules on your data

XML excels at allowing you to create rules for the format of your data. Using either Document Type Definitions (DTDs) or XML Schemas to validate your data gives you two immediate advantages:

1.It helps ensure the accuracy of the information you collect.
2.It helps ensure that the information gathered is in the most usable format for your business

Outputting information in a variety of ways

Outputting your data means releasing it from its storage locker — presumably somewhere inside the guts of your computer — and getting it to some other place where it can be a bit more useful. The great thing about XML documents is that they're not limited to any particular form of output; they can end up in a variety of different places, in whatever form is appropriate — for example, in a database, a computer monitor, a printer, or a PDA.

XML文件是在家里广泛的进程。这句话后处理几乎度身订造的XML ，它意味着信息从一个文件，并用它在一些其他进程或程序。例如，假设您将收到一份订单的形式，一个XML文档。理解的应用程序的XML采购订单可以使用该数据，以确定哪些项目（以及在什么数量）已下令-甚至可以发出指示，另一幅软件生成一个选择列表中，这样的顺序可以采摘，包装，和运往仓库。

在许多情况下， XML文件是使用样式表，以提供高品质的输出在屏幕上。您可以使用相同的数据，但是，将信息发送到语音合成程序，内容的文字的人谁是视障人士。另外，同样的数据也可能创造产值上盲文读者。同样的文件，项目布局和样式也可用于高品质的打印输出。

美丽的这一概念是，你再也不需要大惊小怪和烦躁不安的XML数据创建不同的输出设备。您只需要使用不同的软件，可以读取XML和可提供的输出，以特定的格式或输出设备。
使用相同的数据跨平台

期待的好消息，在第一，如没有新的消息： XML文件没有具体的任何特定平台或编程语言。好吧，这是为什么一些E - mail首页吗？认为多功能性。假设你要Exchange数据库的信息网络上-也就是说，使用Web浏览器发送信息，从用户调查表回Web服务器。为了完成这项任务（和许多其他网站） ，您需要的文件格式，

1 。可扩展：可扩展的格式是一种可定制或自定义的具体应用。
2 。开盘：这是有案可稽的，并广为散发。
3 。非专利药：这表示在接受或标准格式的符号这不是专属财产，一些个人，公司或组织。
这些特点使该文件，以适应不断变化的条件，采取最佳的利用他人的工作，并为了避免引起额外的费用或法律责任。
后果会怎样呢？ XML的满足所有这三个要求的一种文件格式，交换数据-它是开放式，可扩展，和非专有。毫不奇怪，那么， XML是最好的选择，数据交换;这三个魔术特点使它成为一个方便的，一致的方式把数据在多个应用程序和多个平台的最高效和最麻烦。
问题补充：实施规则在您的数据

擅长的XML允许您创建规则的格式，您的数据。使用文档类型定义（ DTDs ）或XML模式，以验证您的资料给你两个直接的好处：

1.It有助于确保信息的准确性您收集。
2.It有助于确保收集的信息是最有用的格式为您的企业

输出信息以各种方式

您的数据输出方式释放它的存储更衣室-大概某处的胆量内您的计算机-获得它的一些其他地方可以有点更加有用。伟大的事情是XML文件，他们不局限于任何特定形式的输出;他们能够最终在各种不同的地方，以任何形式是适当的-例如，在数据库中，计算机显示器，打印机，或者一台PDA 。

去谷歌翻译的凑合看吧
