为什么在根据 XSD 验证 XML 时得到 org.xml.sax.SAXParseException？
Why am I getting org.xml.sax.SAXParseException when validate XML against XSD?
正在尝试正确 XML，但一直出现此错误：
Error - Line 13, 16: org.xml.sax.SAXParseException; lineNumber: 13;
columnNumber: 16; cvc-complex-type.2.4.a: Invalid content was found
starting with element 'me:myself'. One of
'{"urn:Test.Namespace":myself}' is expected.
在这里测试：

您将 "name"、"surname"、...放在 "myself" 元素中。这意味着您将它用作 ComplexType。
但是，您的 xsd 文件并未声明 [=31=] 是 ComplexType。
您必须将 xsd 文件中的 "myself" 元素定义为 ComplexType，就像您为 "laptopy" 元素所做的那样。
此外，不要使用"me:myself"或"uek:copyright"等。只需使用"myself"和"copyright"。
最后，您的 "group" 元素应具有整数类型（如您的 xsd 所述），但您将其与字符串一起使用 "Kr1013".
请参阅下面固定的 XML 代码，该代码现在格式正确并且对于您的 XSD 模式（我没有修改）有效：
