我想選擇「進入」節點，但我無法得到它的工作。

XmlDocument rssDoc = new XmlDocument();    
    XmlNamespaceManager manager = new XmlNamespaceManager(rssDoc.NameTable); 
    manager.AddNamespace("atom", "http://www.w3.org/2005/Atom"); 
    manager.AddNamespace("app", "http://www.w3.org/2007/app"); 
    manager.AddNamespace("cmisra", "http://docs.oasis-open.org/ns/cmis/restatom/200908/"); 
    manager.AddNamespace("cmis", "http://docs.oasis-open.org/ns/cmis/core/200908/"); 
    manager.AddNamespace("alf", "http://www.alfresco.org"); 
    manager.AddNamespace("opensearch", "http://a9.com/-/spec/opensearch/1.1/"); 
    rssDoc.Load(rssStream); 

    XmlNodeList rssItems = rssDoc.SelectNodes("//atom:entry", manager);

出了什麼問題？我嘗試了不同的xpath，但沒有工作。我從調用Alfresco web服務獲取rss。我編輯了原本比較長的xml。

你能夠使用LINQ to XML嗎？我的經驗是，它通常要簡單得多... –

你有沒有試過// *：入口？這樣，你可能會知道它是否是一個命名空間綁定問題。 –

此外，您是否嘗試在構建命名空間管理器之前加載文檔，如下所示：http://support.microsoft.com/kb/316913？只是一個猜測。 –
