为什么在针对 XSD 验证 XML 时收到 org.xml.sax.SAXParseException？

Question

尝试制作正确的 XML，但不断收到此错误：

错误 - 第 13、16 行：org.xml.sax.SAXParseException；行号：13； 列号：16； cvc-complex-type.2.4.a：发现无效内容 从元素“我：我自己”开始。之一 '{"urn:Test.Namespace":myself}' 是预期的。

在这里测试：

代码： .xml：

<?xml version="1.0" encoding="utf-8" ?>

Answer 1

您将“姓名”、“姓氏”……放在“我自己”元素中。这意味着您将其用作 ComplexType。 但是，您的 xsd 文件并未说明“我自己”是一个 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。

另外，不要使用“me:myself”或“uek:copyright”等。只需使用“myself”和“copyright”即可。

最后，您的“组”元素应该具有整数类型（如您的 xsd 所述），但您将其与字符串“Kr1013”一起使用。

请参阅下面的固定 XML 代码，该代码现在格式正确且适用于您的 XSD 架构（我没有修改）：
