如何在不指定XML模式中的顺序的情况下验证子元素是否存在?

如何在不指定XML模式中的顺序的情况下验证子元素是否存在?,xml,xsd,xsd-1.0,Xml,Xsd,Xsd 1.0,我正在尝试开发一个XML模式文件来验证Person元素。我们的应用程序要求一个人有名和姓,但不关心他们的顺序。它还允许将其他元素放在Person元素下。因此,以下各项是有效的: <person> <firstName>Jon</firstName> <lastName>Smith</lastName> </person> <person> <lastName>Smith<

我正在尝试开发一个XML模式文件来验证
Person
元素。我们的应用程序要求一个人有
,但不关心他们的顺序。它还允许将其他元素放在
Person
元素下。因此,以下各项是有效的:

<person>
    <firstName>Jon</firstName>
    <lastName>Smith</lastName>
</person>

<person>
    <lastName>Smith</lastName>
    <firstName>Jon</firstName>
</person>

<person>
    <title>Mr</title>
    <firstName>Jon</firstName>
    <lastName>Smith</lastName>
</person>

<person>
    <title>Mr</title>
    <lastName>Smith</lastName>
    <firstName>Jon</firstName>
    <suffix>CEng</suffix>
</person>

<person>
    <title>Mr</title>
    <lastName>Smith</lastName>
    <middleInitial>G</middleInitial>
    <firstName>Jon</firstName>
    <suffix>CEng</suffix>
</person>
我尝试创建一个复杂类型,如下所示:

<xsd:element name="person">
    <xsd:complexType>
        <xsd:all>
            <xsd:element minOccurs="1" maxOccurs="1" name="firstName" />
            <xsd:element minOccurs="1" maxOccurs="1" name="lastName"/>
            <xsd:any minOccurs="0" maxOccurs="unbounded" processContents="skip" />
        </xsd:all>
    </xsd:complexType>
</xsd:element>


但是显然
any
不允许在
all
中使用。是否可以获取XML模式来执行此验证?如果是,如何进行?

如果您有XML Schema 1.1验证程序:

<xsd:element name="person">
    <xsd:complexType>
        <xsd:sequence>
            <xsd:any minOccurs="0" maxOccurs="unbounded" processContents="skip" />
        </xsd:sequence>
    </xsd:complexType>
    <xsd:assert test="firstName and lastName"/>
</xsd:element>

在xsd 1.1中,xsd:all中包含xsd:any是有效的,但如果未指定的元素与firstName和lastName位于同一命名空间中,它仍然可能导致错误,因为内容模型可能不明确。但是xsd:assert可以工作

在XSD1.0中,可以将元素的所有顺序指定为带有选项的序列。但是,除firstName和lastName之外的元素需要位于不同的名称空间中,否则在模式中会出现“不明确的内容模型”错误。我不确定您是否可以在数据中使用这个“其他名称空间”约束,但我认为这是在XMLSchema版本1.0中对此进行建模的唯一方法

我现在使用的是.Net 4.0,可惜不是。除非有人知道第三方库有什么好处。好的,我的答案在1.0中有点扩展。不确定这是否对你有效,但我相信这是你能得到的最接近的。
