当针对XSD验证XML时，为什么会出现org.xml.sax.SAXParseException？

Question

尝试制作适当的XML，但不断出现此错误：

错误-第13行，16：org.xml.sax.SAXParseException； lineNumber：13; columnNumber：16； cvc-complex-type.2.4.a：发现无效的内容，以元素“ me：myself”开头。 预期为“ {{urn：Test.Namespace“：myself}”之一。

在这里测试：

代码：.xml：

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

Answer 1

您将“名称”，“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文件没有声明“我自己”是ComplexType。 您必须将xsd文件中的“ myself”元素定义为ComplexType，就像您对“ laptopy”元素所做的一样。

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

最后，“ group”元素应具有整数类型（如xsd所示），但是您可以将其与字符串“ Kr1013”一起使用。

请参阅下面的固定XML代码，它在您的XSD模式（我未修改）方面已经形成并且有效：
