关于RSS节点数据读取的一些疑惑

symboltome 2008-05-20 10:20:33

最近完成了一些简单的rss资源读取
但下面这个情况让我以后
- <title>- 疤痕修复：忘记不愉快的往事 </title> （这种能正常的读取内容）

- <title>
- <![CDATA[ 疤痕修复：忘记不愉快的往事
]]>
</title> ============================== （这种读取出来就是空的了）

我的读取操作如下：

先读取到节点title，然后取节点的值用的 “InnerText"
麻烦那位大哥清楚的给一些指点谢谢

我改了一下, 读取成功,你试一下:

rss.xml



<?xml version="1.0" encoding="utf-8" ?>

<item>

<title>

  <![CDATA[ 疤痕修复：忘记不愉快的往事 ]]>

</title>

</item>

xml.aspx



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

XPATH ？？不行哦

你看我的嘛

doc.Load(RssUrl);
XmlNodeList nodelist = doc.GetElementsByTagName("item");
XmlNodeList objItems1;
int i = 0;
if (doc.HasChildNodes)
{
foreach (XmlNode node in nodelist)
{
string title = " ";
string link = " ";
i += 1;
if (node.HasChildNodes)
{
objItems1 = node.ChildNodes;
foreach (XmlNode node1 in objItems1)
{
switch (node1.Name)
{
case "title ":
title = node1.InnerText;
break;
case "link ":
link = node1.InnerText;
break;
}
if (title != " " && link != " ")
break;
}
Rss += " <a href= ' " + link + " ' target= '_blank '> " + title + " </a> <br> ";

}
