正象HTML一样,可扩展标记语言XML(Extensible Markup Language)也是一种标记语言。它是互联网上结构化的文件交换的一种数据模式,因而成为网上传送结构化数据的工具,它同样依赖于描述一定规则的标签和能够读懂这些标签的应用处理工具来发挥它的强大功能。这一点,从XML的命名上也可窥见一斑。 XML的强大功能主要来自于其可扩展性。业界观察家认为XML将使信息交换方式发生变革,就象HTML改变了用户界面一样。但XML并非象HTML那样,提供一组事先已经定义好的标签,而是提供一种标准,利用这个标准,用户可以根据实际需要定义自己的新的标记语言,并为该自定义的标记语言规定其特有的一套标签,如XML允许开发人员为价格、产品等数据创建他们自己的标记,这样的结果是获得更加有效的数据交换和更好的Internet搜索能力。
Just as HTML, Extensible Markup Language (XML) is also a markup language. It is a data model for structured document exchange over the internet and thus becomes a tool for delivering structured data online and also relies on labels that describe certain rules and application processing tools that can read these labels for their power . This point, from the naming of XML can also be glimpsed. The power of XML comes primarily from its scalability. Industry watchers believe that XML will change the way information is exchanged, just as HTML changes the user interface. XML, however, does not provide a set of predefined tags as HTML does, but provides a standard by which users can define their own new markup language as needed and define the custom markup language Its unique set of tags, such as XML, allows developers to create their own tags for data such as price, product, etc. The result is more efficient data exchange and better Internet search capabilities.
