使用eclipse我已經擺脫了所有錯誤，但是當我更改xml文檔中的元素內容超出了.xsd文件中設置的限制時，不會出現驗證錯誤。我試過用http://www.freeformatter.com/xml-validator-xsd.html在線驗證它，我得到錯誤「Cvc-elt.1：找不到元素'DatabaseInventory'的聲明'。'行'4，列'69'」但在日食它驗證罰款。不知道我做錯了什麼。xml文檔未驗證到xsd模式
這是我的XML

The following database should be considered the most stable for up-to-date
data. The backup strategy includes running the database in Archive Log Mode
and performing nightly backups. All new accounts need to be approved by the
DBA Group before being created.
