如何解析XDocument（易趣）項目（列表）使用Visual Basic？

<code> 
     For Each oXElement In oXDocument.Descendants("searchResult") 
       sTitle = oXElement.Element("title").Value 
     Next 
</code>

我也曾嘗試：如何解析XDocument（易趣）項目（列表）使用Visual Basic？

<code> 
     For Each oXElement In oXDocument.Elements(searchResults) 
      sTitle = oXElement.Element("title").Value 
     Next 
</code>

我有麻煩節點的保持，以及瞭解你的XDocument節點進行通信的方式。

我的最終目標是從所有易趣元素的屬性創建易趣對象模型。爲此，我需要以某種方式引用XML標記 - 在這裏我將非常感謝您的建議或示例示例，可以讓我繼續解析此XML響應。

非常感謝您的幫助。 PS：我已經搜索了類似的問題，發現了一些相同的類型，但仍然無法讓我的解析工作。

你有你的查詢XML時使用XNamespace例如：

Dim ns = XNamespace.Get("http://www.ebay.com/marketplace/search/v1/services")

而且隨着它添加到每個Descendants，Elements，Element，Attributes，Attributes等叫你做：

For Each oXElement In oXDocument.Descendants(ns + "searchResult") 
     sTitle = oXElement.Element(ns + "title").Value 
Next 

For Each oXElement In oXDocument.Elements(ns + searchResults) 
    sTitle = oXElement.Element(ns + "title").Value 
Next

兩件事。首先，你落入陷阱，捕捉使用LINQ to XML問題的人中有90％的人。你忘了命名空間。您可以使用它在C＃或VB工作如下：

Dim ns = XNamespace.Get("http://www.ebay.com/marketplace/search/v1/services")

VB也可以讓你使用進口的命名空間，就像你在你的文件的頂部導入其他.NET命名空間。此選項的優點是，如果您的項目中有模式，則可在構建查詢時通過XML結構獲得智能感知。

Imports <xmlns:eb="http://www.ebay.com/marketplace/search/v1/services">

第二個問題是標題元素不是searchResult的直接子元素，而是嵌套更深層次的附加層次。這是一個利用命名空間導入的示例。我使用VB XML Literals作爲後代（...），以便與任何給予C＃偏見答案的人形成鮮明對比;-)
