cvc-complex-type.4：属性 {0} 必须出现在元素 {1} 上

Question

我是 xml 的新手，正在尝试使用相应的 xsd 验证 xml 但遇到错误：

cvc-complex-type.4: Attribute 'Companyname' must appear on element 'company'

尽管我已经在 xml 和 xsd 中添加了公司名称。什么可能导致此错误。任何 help/suggestion?

XML:

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

        <employee empid="fsd" ename="fuehuf" emailid="fhueh" phoneno="364764"> </employee>
        <employee empid="fsd" ename="fuehuf" emailid="fhueh" phoneno="364764"> </employee>
        <contractEmployee name="fdsf" phoneno="12345"> </contractEmployee>
    </department>
</company>

companyxsd.xsd:

您的 XML 包含一些错误。它的格式不正确（开始标记与结束标记不匹配）并且包含许多违反您的架构的内容（employee 和 contractEmployee 标记必须为空）。

我已经清理了你的 XML:

<?xml version="1.0" encoding="utf-8"?>
<company Companyname="abc" address="hj" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <department dname="dfsdf" deptphoneno="1232321" deptfaxno="2323" deptemail="fefsf">
        <employee empid="fsd" ename="fuehuf" emailid="fhueh" phoneno="364764"/>
        <employee empid="fsd" ename="fuehuf" emailid="fhueh" phoneno="364764"/>
        <contractEmployee name="fdsf" phoneno="12345"/>
    </department>
</company>

这可以根据您的模式正确验证，例如可以测试在 this site.

您可能遇到的任何其他问题都与您执行验证的方式有关，与 XML 或 XSD 内容无关。
