解析XML時出現問題？

Question

我正在C＃中製作一個簡單的RSS閱讀器應用程序。這是我第一次使用XML，並且需要一些幫助來解析各種rss提要中使用的不同樣式。

如

以下是飼料的類型，我期待並獲得正確的結果有：

<item> 
     <title>Cometh the hour, cometh the man</title> 
     <link>http://www.espnstar.com/rss-feed/detail/item612327</link> 
     <description>Real Madrid have finally won their first trophy since 2008. Unsurprisingly, it has coincided with the arrival of one man.</description>

但飼料，如：

我如何提取主要描述文本從描述節點而不是像hrefs的其他東西。

如何像飼料處理CDATA：

<item> 
<title><![CDATA[Japan declares no-go zone around nuclear plant ]]></title> 

<author><![CDATA[AP]]></author> 
<category><![CDATA[International]]></category> 
<link>http://www.thehindu.com/news/international/article1714401.ece</link>

Answer 2

嗯，你可以使用正則表達式來擺脫一切你並不需要。

XElement d = XElement.Parse(feed); // load the feed in an XElement 

// get the title, link and description 
string title = d.Elements("title").FirstOrDefault().Value; 
string link = d.Elements("link").FirstOrDefault().Value; 
string description = d.Elements("description").FirstOrDefault().Value; 

// remove everything that's between '<>' 
Regex r = new Regex(@"<.*>"); 
description = r.Replace(description, ""); 

對於第二個飼料，結果將是：聖安東尼奧馬刺隊，在半場結束時以三分落後，反彈在1-1與地級與孟菲斯灰熊隊的第一輪季後賽系列賽93-87勝利。第一個Feed會保持不變，第三個Feed會自動忽略所有CDATA的內容。
