查看 XSL 文件。

上面这个 XSL 文件会循环遍历 XML 文件中的元素，并为每个 XML "field" 元素创建一个输入域。field 元素的 id 属性的值被添加到每个 HTML 输入域的 id 和 name 属性。"value" 元素的值被添加到每个 HTML 输入域的 "value" 属性。结果是，可以得到一个包含 XML 文件中值的可编辑的 HTML 表单。

然后，我们还有第二个样式表："tool_updated.xsl"。这个 XSL 文件会被用来显示已更新的 XML 数据。这个样式表不会输出可编辑 HTML 表单，而是一个静态的 HTML 表格：







Updated Tool Information:

ASP 文件

在上面 "tool.xsl" 文件中， HTML 表单的 action 属性的值是 "edittool.asp" 。

Tip:If you do not know how to write ASP, please learn ourASP Tutorial》。

Note:We are converting and updating the XML files located on the server. This is a cross-platform solution. The client can only obtain HTML returned from the server - and HTML can run on any browser.
