**课程名称：XML 入门** **课程概述：** 本课程将带您深入了解 XML（eXtensible Markup Language），一种用于存储和传输数据的标记语言。与 HTML 类似，但 XML 的最大特点在于其**可扩展性**。 **核心要点：** * **XML 的本质：** XML 是一种标记语言，专为存储和传输数据而设计。 * **自描述性：** XML 具有自描述性，允许用户定义自己的自定义标签，这与预定义标签的 HTML 不同。 * **自定义标签：** XML 的作者需要自行定义标签和文档结构。 * **灵活性：** 大多数 XML 应用在添加或删除新数据时仍能正常工作。 * **平台和语言无关性：** XML 独立于平台和语言，可在大多数操作系统和编程语言中使用。 * **简化数据处理：** XML 极大地简化了数据共享、数据传输、平台迁移和数据可用性。 * **解决数据兼容性问题：** 许多计算机系统的数据格式不兼容，导致数据交换和迁移耗时且易丢失。XML 以纯文本格式存储数据，提供了软件和硬件无关的数据存储、传输和共享方式，使得升级系统或应用时数据不易丢失。 * **广泛的可用性：** XML 使得数据能够被各种“读取机器”访问，包括人类、计算机、语音设备、新闻源等。 **总结：** “XML 入门”课程旨在让学习者掌握 XML 的基本概念和优势，理解其如何简化数据管理和提高数据互操作性，为处理和交换跨系统、跨平台的数据奠定坚实基础。
What is XML?XML stands for eXtensible Markup LanguageXML is a markup language much like HTMLXML was designed to store and transport dataXML was designed to be self-descriptiveXML is a W3C RecommendationThe XML language has no predefined tags.XML allows you to define your own custom tags unlike HTML that has pre-defined tags.With XML, the author must define both the tags and the document structure.Most XML applications will work as expected even if new data is added (or removed).XML is platform and language neutral and independent which means it will work with most operating systems and programming languages.XML Simplifies ThingsXML simplifies data sharingXML simplifies data transportXML simplifies platform changesXML simplifies data availabilityMany computer systems contain data in incompatible formats. Exchanging data between incompatible systems (or upgraded systems) is a time-consuming task for web developers. Large amounts of data must be converted, and incompatible data is often lost.XML stores data in plain text format. This provides a software- and hardware-independent way of storing, transporting, and sharing data.XML also makes it easier to expand or upgrade to new operating systems, new applications, or new browsers, without losing data.With XML, data can be available to all kinds of "reading machines" like people, computers, voice machines, news feeds, etc.
