XSD模式针对我的XML文档的两部分正确验证

Question

So I have an XSD document that's validating correctly against my XML up to a certain level. As soon as a I had another DatabaseName element or Webserver element or both, an error comes up saying "element not expected here." Not too sure what's the problem - can anyone help?

XML:

      <?xml version="1.0" encoding="ISO8859-1" ?>

Your content model for Inventory only allows a single DatabaseName.

Instead of all(DatabaseName, WebserverName) , use the content model

choice minOccurs=0 maxOccurs=unbounded
  element DatabaseName
  element WebserverName
