几乎所有的主流浏览器均支持XML和XSLT。

Mozilla Firefox

从1.0.2版本开始,Firefox就已开始支持XML和XSLT(包括CSS)。

Mozilla

Mozilla含有用于XML解析的Expat,并支持显示XML CSS。Mozilla同时拥有对Namespaces的某些支持。

Mozilla同样可做到对XSLT的执行(XSLT implementation)。

Netscape

自从版本8开始,Netscape开始使用Mozilla的引擎,因此它对XML / XSLT的支持与Mozilla是相同的。

Opera

自从版本9开始,Opera已经可支持XML / XSLT(以及CSS)。版本8仅支持XML CSS。

Internet Explorer

自从版本6开始,Internet Explorer就开始支持XML、Namespaces、CSS、XSLT以及XPath。

注释:Internet Explorer 5同样拥有对XML的支持,但是XSL部分与W3C的官方标准不兼容!

查看XML文件

在下列浏览器中均可查看原始的XML文件:Mozilla、Firefox、Opera、Internet Explorer以及Netscape 6 。

不过,如果需要把XML显示为网页,那么您需要添加一些显示信息。

查看XML文件

在 Firefox 和 Internet Explorer 中:

打开XML文件 - XML文档将显示为代码颜色化的根以及子元素。通过点击元素左侧的加号或减号,可以展开或收起元素的结构。如需查看不带有 和 - 符号的源代码,请从浏览器菜单中选择“查看源代码”。

在 Netscape 6 中:

打开XML文件,然后在XML文件中右击,并选择查看“查看源代码”。XML文档将显示为代码颜色化的根以及子元素。

在 Opera 7 和 8 中:

在Opera 7,打开XML文件,然后在XML文件中右击,选择"Frame" / "View Source"。XML文档将显示为纯文本。在Opera 8中:打开XML文件,然后在XML文件中右击,选择"Source"。XML文档将显示为纯文本。

查看此XML文件:

以下为引用的内容:
<?xml version="1.0" encoding="ISO-8859-1" ?>
- <!-- Edited with XML Spy v2007 (http://www.altova.com)
-->
- <note>
<to>Tove</to>
<from>Jani</from>
<heading>Reminder</heading>
<body>Don't forget me this weekend!</body>
</note>

注释:不要期望XML文件会像HTML文档那样被格式化!

查看某个无效的XML文件

如果浏览器打开了某个有错误的XML文件,那么它会报告这个错误。

请查看这个XML文件:

以下为引用的内容:
<?xml version="1.0" encoding="ISO-8859-1" ?>
- <!-- Edited with XML Spy v2007 (http://www.altova.com)
-->
- <note>
<to>Tove</to>
<from>Jani</from>
<heading>Reminder</heading>
<body>Don't forget me this weekend!</body>
</note>

其他的XML实例

请查看这些XML文档,这会有助于您建立对XML的感性认识。

为什么XML会这样显示?

XML文档不会携带有关如何显示数据的信息。

由于XML标签由XML文档的作者“发明”,浏览器无法确定像<table>这样一个标签究竟描述一个HTML表格还是一个餐桌。

在没有任何有关如何显示数据的信息的情况下,大多数的浏览器都会仅仅把XML文档显示为源代码。

在下面的章节,我们会了解几个有关这个显示问题的解决方案,其中会使用CSS、XSL、JavaScript以及XML数据岛。
