XSD基complexType

Question

我想配置一个基类型，它有具体的子类型。可以通过配置只允许一个子元素的元素来使用此类型。

<xs:complexType name="VcsType">
    <xs:sequence>
        <xs:element name="enabled" type="xs:boolean" default="false" minOccurs="1"/>
    </xs:sequence>
</xs:complexType>

<xs:complexType name="GitVcsType">
    <xs:complexContent>
        <xs:extension base="VcsType">
            <xs:sequence>
                <xs:element name="url" type="xs:string" minOccurs="1"/>
            </xs:sequence>
        </xs:extension>
    </xs:complexContent>
</xs:complexType>

<xs:complexType name="SvnVcsType">
    <xs:complexContent>
        <xs:extension base="VcsType">
            <xs:sequence>
                <xs:element name="version" type="xs:string" minOccurs="1"/>
            </xs:sequence>
        </xs:extension>
    </xs:complexContent>
</xs:complexType>

现在我想说的是：

<xs:element name="vcs" type="VcsType" minOccurs="0"/>

它将被相应地替换(如果是git/svn等)。我怎么能这么做？

从我已经看到的情况来看，这只是缺少的XML方面的东西。

您有一个模式

​

<?xml version="1.0" encoding="utf-8" ?>
<!-- Created with Liquid XML 2015 Designer Edition (Trial) 13.0.1.5719 (http://www.liquid-technologies.com) -->
<xs:schema elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema">
    <xs:element name="vcs" type="VcsType" />
    <xs:complexType name="VcsType">
        <xs:sequence>
            <xs:element name="enabled" type="xs:boolean" minOccurs="1" default="false" />
        </xs:sequence>
    </xs:complexType>
    <xs:complexType name="GitVcsType">
        <xs:complexContent>
            <xs:extension base="VcsType">
                <xs:sequence>
                    <xs:element name="url" type="xs:string" minOccurs="1" />
                </xs:sequence>
            </xs:extension>
        </xs:complexContent>
    </xs:complexType>
    <xs:complexType name="SvnVcsType">
        <xs:complexContent>
            <xs:extension base="VcsType">
                <xs:sequence>
                    <xs:element name="version" type="xs:string" minOccurs="1" />
                </xs:sequence>
            </xs:extension>
        </xs:complexContent>
    </xs:complexType>
</xs:schema>

由于从VscType派生了两件事，所以可以根据VscType本身、GitVscType或SvnVscType创建一个文档。

这会导致

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