XML中的递归元素

XML中的递归元素,xml,xsd,Xml,Xsd,我试图在XML模式中设计和实现一个递归元素,但总体上我对XML不是很在行。关于如何设计它有什么想法吗?下面的模型基于一种创作风格,其中元素声明是全局的,递归性是通过引用元素定义实现的 <?xml version="1.0" encoding="utf-8" ?> <!--XML Schema generated by QTAssistant/XML Schema Refactoring (XSR) Module (http://www.paschidev.com)-->

<?xml version="1.0" encoding="utf-8" ?>
<!--XML Schema generated by QTAssistant/XML Schema Refactoring (XSR) Module (http://www.paschidev.com)-->
<xsd:schema targetNamespace="http://tempuri.org/XMLSchema.xsd" elementFormDefault="qualified" xmlns="http://tempuri.org/XMLSchema.xsd" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <xsd:element name="recursive">
        <xsd:complexType>
            <xsd:sequence>
                <xsd:element ref="recursive" minOccurs="0"/>
            </xsd:sequence>
        </xsd:complexType>
    </xsd:element>
</xsd:schema>
或者,您可以通过重新使用类型来实现相同的功能:

<?xml version="1.0" encoding="utf-8" ?>
<!--XML Schema generated by QTAssistant/XML Schema Refactoring (XSR) Module (http://www.paschidev.com)-->
<xsd:schema targetNamespace="http://tempuri.org/XMLSchema.xsd" elementFormDefault="qualified" xmlns="http://tempuri.org/XMLSchema.xsd" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <xsd:element name="recursive" type="Trecursive"/>
    <xsd:complexType name="Trecursive">
        <xsd:sequence>
            <xsd:element name="recursive" type="Trecursive" minOccurs="0"/>
        </xsd:sequence>
    </xsd:complexType>
</xsd:schema>
或者,您可以选择介于两者之间的某个位置:

<?xml version="1.0" encoding="utf-8" ?>
<!--XML Schema generated by QTAssistant/XML Schema Refactoring (XSR) Module (http://www.paschidev.com)-->
<xsd:schema targetNamespace="http://tempuri.org/XMLSchema.xsd" elementFormDefault="qualified" xmlns="http://tempuri.org/XMLSchema.xsd" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
    <xsd:element name="recursive" type="Trecursive"/>
    <xsd:complexType name="Trecursive">
        <xsd:sequence>
            <xsd:element ref="recursive" minOccurs="0"/>
        </xsd:sequence>
    </xsd:complexType>
</xsd:schema>
