簡單的XML問題

Question

好的，使用我的XML編輯器檢查驗證，我得到“驗證已停止在第2行第8列：沒有找到元素'Staff'的聲明。有人知道為什么嗎？

另外，每三名工作人員具有不同的類型，每種類型都包含不同的元素（例如，兼職工作人員僅具有電子郵件，姓名，職位，而全職類型具有有關所有元素的信息。）擁有元素是否不好？數據留空？ 如果它們是不同類型的StaffMembers，是否可以消除多余的元素，還是每個StaffMember始終都需要相同的元素？ 謝謝！

Answer 1

這個XML驗證器不會給您的xml提供任何錯誤。

無論如何，如果您使用模式或DTD進行驗證，則可能會出現錯誤（如果它不符合規范）。

第二點，您可以有一個空節點，但使用情況取決於您的需求，如果使用一個，則取決於規范，以及將使用此xml的代碼。 如果您沒有像我懷疑的那樣使用架構或DTD，或者以后解析它的代碼都照顧到了它們，則可以刪除它們。

Answer 2

“驗證在第2行第8列停止：找不到元素'Staff'的聲明。有人知道為什么嗎？

因為您尚未聲明要驗證的架構（XML Schema，DTD，RNG等）。 我不知道您使用的是哪種XML編輯器...顯然，您告訴它進行驗證，並且它試圖說它無法驗證，因為沒有要驗證的架構。 這並不意味着你的XML是無效的：相反，它意味着有效性已經為XML沒有意義的（除非您的模式與之相關聯）。
