針對XSD的xml驗證：從元素xxx開始發現無效的內容
[英]xml validation against XSD: Invalid content was found starting with element xxx

我逐個驗證了文件，然后在Web和NetBeans上相互驗證，但是當我運行應用程序時，總是會遇到此錯誤：
org.xml.sax.SAXParseException：cvc-complex-type.2.4.a：發現無效的內容（從元素'lastSave'開始）。 預期為“ {” http://www.dei.isep.ipp.pt/lapr4“：numSpreadsheets }”之一。
我一直在尋找答案，但是似乎沒有任何效果，有人可以給我一些解決問題的方法嗎？
提前致謝。

您的XSD文件中的</xs:schema>關閉標簽有兩倍。 嘗試刪除首次出現的XSD處理器。
另外，您在<spreadsheet />標記的底部缺少<cell />元素。
這驗證了所有權利：
