服务器上的 XML

---

XML 文件是类似 HTML 文件的纯文本文件。

XML 能够通过标准的 Web 服务器轻松地存储和生成。

在服务器上存储 XML 文件

XML 文件在 Internet 服务器上进行存储的方式与 HTML 文件完全相同。

启动 Windows 记事本，并写入以下行：

<?xml version="1.0" encoding="ISO-8859-1"?>
<note>
<from>Jani<https:https:.php.phpwww.kongruo.cn.phpa.php9.phphttps:.php.phpwww.kongruo.cn.phpa.php9.phpwww.kongruo.cnhttps:.php.phpwww.kongruo.cn.phpa.php9.phpahttps:.php.phpwww.kongruo.cn.phpa.php9.php9https:.php.phpwww.kongruo.cn.phpa.php9.php.phpfrom>

然后用适当的文件名，比如 "note.xml"，在 Web 服务器上保存这个文件。

通过 ASP 生成 XML

XML 可在不安装任何 XML 软件的情况下在服务器端生成。

如需从服务器生成 XML 响应 - 只需简单地编写以下代码并在 Web 服务器上把它保存为一个 ASP 文件：

<%

在服务器上通过 XSLT 转换 XML

下面的 ASP 代码在服务器上把 XML 文件转换为 XHTML：

<%
'Load XML
set xml = Server.CreateObject("Microsoft.XMLDOM")
xml.async = false
xml.load(Server.MapPath("simple.xml"))

'Load XSL
set xsl = Server.CreateObject("Microsoft.XMLDOM")
xsl.async = false
xsl.load(Server.MapPath("simple.xsl"))

'Transform file
Response.Write(xml.transformNode(xsl))
%>

实例解释

• 第一个代码块创建微软 XML 解析器的实例（XMLDOM），并把 XML 文件载入内存。
• 第二个代码块创建解析器的另一个实例，并把 XSL 文件载入内存。
• 最后一个代码使用 XSL 文档来转换 XML 文档，并把结果以 XHTML 发送到您的浏览器。

  看看上面的代码怎么运行。

  通过 ASP 把 XML 保存为文件

  这个 ASP 实例会创建一个简单的 XML 文档，并把该文档保存到服务器上：

  <%
