复杂类型的 XML 模式包含 <xs:all>和&lt;xs:any&gt;? [英] XML Schema with complext type containing &lt;xs:all&gt; and &lt;xs:any&gt;?

问题描述

我想定义一个复杂类型，其中包含可能存在也可能不存在的元素，并且还允许其他未定义的元素，所以我得到了这样的东西:

I want to define a complex type that contains elements that may or may not exist, and also allows for additional undefined elements so I've got something like this:

<xs:complexType name="MyType">
 <xs:sequence>
  <xs:element name="A" type="xs:float" minOccurs="0" maxOccurs="1" />
  <xs:element name="B" type="xs:float" minOccurs="0" maxOccurs="1" />
  <xs:element name="C" type="xs:float" minOccurs="0" maxOccurs="1" />
  <xs:any minOccurs="0" processContents="skip"/>
 </xs:sequence>
</xs:complexType>

我不想使用 强制顺序，所以我想将 更改为 <;xs:all> 但随后 是不允许的.有没有办法做到这一点?

I don't want to force the order using <xs:sequence> so I want to change the <xs:sequence> to <xs:all> but then <xs:any> isn't allowed. Is there some way to accomplish this?

推荐答案

要允许任何顺序，请使用:

To allow any order, use this:

<xs:complexType name="MyType"> 
 <xs:all minOccurs="1" maxOccurs="1"> 
  <xs:element name="A" type="xs:float" minOccurs="0" maxOccurs="1" />
  <xs:element name="B" type="xs:float" minOccurs="0" maxOccurs="1" />
  <xs:element name="C" type="xs:float" minOccurs="0" maxOccurs="1" />
 </xs:all>
</xs:complexType> 

但是，您不能在 中包含 .
也不能将它们都包含在一种类型中，直接或作为扩展.

But then, you can't have an <any> inside an <all>.
Nor can you have them both inside one type, either directly or as an extension.
