我從Web服務中提取XML集，將其加載到XDocument中，然後解析出來。在一個節點上，如果我將XML輸出到一個文件，那麼該屬性是CLEARLY，它告訴我它不存在。我無法弄清楚我正在做什麼愚蠢的事情導致這個錯誤。現有節點的XDocument屬性不存在

我的代碼可以找到OWNED_PROPERTY就好了的SequenceNumber值，但對抵押品炸燬：

所以我要去哪裏錯了？除了XML中的文本以外，唯一不同的是OWNED_PROPERTY標籤位於附加標籤下，而直接位於下方。但正如你所看到的，我的代碼正在跳過標籤，因爲它對我的目的沒用。
您使用命名空間中的代碼，但您的樣品不使用任何人;用一個更真實的例子可能會更容易發現問題。 –
你似乎也不明白'。Descendants（）會搜索節點下的整個樹，而不僅僅是下一個元素。大部分代碼是非常不必要的 – Jonesopolis
'fxl'應該是所有的「element2的」元素的集合，但你在你的foreach調用'Elements'上，基本上讓「element2的」元素的所有孩子培養成'elfx '，那麼你就調用'Element'來尋找一個「element2」。我沒有看到你的代碼如何與這個例子一起工作。 – juharr
