现实生活中的 XML - XML 基础教程 - 简单教程，简单编程

接下来我们使用一些范例来演示如何使用 XML 交换信息

范例：XML 新闻

XML News 是用于交换新闻和其他信息的规范

对新闻的供求双方来说，通过使用 XML 这种标准，可以使各种类型的新闻信息通过不同软硬件以及编程语言进行的制作、接收和存档更加容易

    <head>
        <title>Colombia Earthquake</title>
    </head>
    <body>
        <headline>
            <hl1>143 Dead in Colombia Earthquake</hl1>
        </headline>
