Asp.net 在网页上输出xml

前台页面

原网页如下：

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default2.aspx.cs" validateRequest="false" Inherits="Default2" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
    
    </div>
    </form>
</body>
</html>

删除无用html标签后：

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default2.aspx.cs" validateRequest="false" Inherits="Default2" %>

后台文件

string para = "<?xml version='1.0' encoding='GB2312' ?>";
para += "<book>";
para += "<name>《心理学》</name>";
para += "<price> 100</price>";
para += "</book>";
Response.ContentType = "text/xml";
Response.Write(para);

解析页面上的xml

XmlDocument xml = new XmlDocument();
xml.LoadXml(para);
string name = xml.SelectSingleNode("//book/name").InnerText;string price = xml.SelectSingleNode("//book/price").InnerText;

url 编码

xml 字符串作为 url参数时会引起错误，需要编码。

请求方：

string para = "<?xml version='1.0' encoding='GB2312' ?>";
para += "<book>";
para += "<name>《心理学》</name>";
para += "<price> 100</price>";
para += "</book>";
para = System.Web.HttpUtility.UrlEncode(para, System.Text.Encoding.GetEncoding("GB2312"));

接收方：

string para = Request.QueryString["para"].ToString();
para = System.Web.HttpUtility.UrlDecode(para, System.Text.Encoding.GetEncoding("GB2312"));
