如何在XSD中声明多个组？

Question

在我的方案中，我的 XSD 应该在一个根标记下有多个组，     ＃XSD＃          

bootstrap cdn's

当我使用xml验证时，它说这种格式错了， 任何人都可以帮助我知道如何创建多个组

您错过了复杂类型中的序列

<?xml version="1.0" encoding="utf-8" ?>
<!--Created with Liquid Studio 2017 - Developer Bundle Edition (Trial) 15.0.0.7089 (https://www.liquid-technologies.com)-->
<xs:schema elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema">
    <xs:group name="location">
        <xs:sequence>
            <xs:element name="city" type="xs:string" />
            <xs:element name="flat_num" type="xs:string" />
            <xs:element name="landmark" type="xs:string" />
            <xs:element name="street" type="xs:string" />
        </xs:sequence>
    </xs:group>
    <xs:group name="student">
        <xs:sequence>
            <xs:element name="firstname" type="xs:string" />
            <xs:element name="lastname" type="xs:string" />
            <xs:element name="mothername" type="xs:string" />
            <xs:element name="fathername" type="xs:string" />
        </xs:sequence>
    </xs:group>
    <xs:element name="Student_details" type="details" />
    <xs:complexType name="details">
        <xs:sequence>
            <xs:group ref="location" />
            <xs:group ref="student" />
        </xs:sequence>
    </xs:complexType>
</xs:schema>

我还会质疑一个小组是否最能实现你想要描述的内容。您目前拥有的将生成这样的XML

<?xml version="1.0" encoding="utf-8"?>
<!-- Created with Liquid Studio 2017 - Developer Bundle Edition (Trial) 15.0.0.7089 (https://www.liquid-technologies.com) -->
<Student_details xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
                 xsi:noNamespaceSchemaLocation="Schema.xsd">
    <city>string</city>
    <flat_num>string</flat_num>
    <landmark>string</landmark>
    <street>string</street>
    <firstname>string</firstname>
    <lastname>string</lastname>
    <mothername>string</mothername>
    <fathername>string</fathername>
</Student_details>
