作为特定复杂类型的扩展的任何类型元素的 xsd 序列 [英] xsd sequence of any type of element that is an extension of specific complex type

问题描述

基本上，如果这是 .NET，它看起来像这样:

Basically if this was .NET, it would look like this:

ISomething
{
  string A { get; }
  int B { get; }
}

var somethings = new List<ISomething>();
something.Add(new SomethingSomething());
something.Add(new AnotherSomething());
something.Add(new AnythingSomething());

基本上我希望元素序列可以任意命名，只要它们的复杂类型是我定义的复杂类型的扩展.

Basically I want the sequence of elements to be named anything they want to be, as long as their complex type is an extension of a complex type I define.

所以它可能看起来像:

<somethings>
  <something-something a="foo" b="0" />
  <another-something a="bar" b="1" />
  <example:anything-something a="baz" b="2" />
</somethings>

我确定这是可能的，我猜的替代方案是组合，其中我有一个标准元素，其中可以包含一个至少是某物"的子元素..

I'm sure this is possible, the alternative I guess is composition, where I have a standard element that can contain a single child that is at least a 'Something'..

提前致谢，xsd 不是我的强项.

Thanks in advance, xsd isn't my strong point.

编辑，好吧，到目前为止我发现的最接近的东西基本上是:

Edit, ok the closest thing I've found so far is basically:

<somethings>
  <something xsi:type="something-something" a="foo" b="0" />
  <something xsi:type="another-something" a="bar" b="1" />
  <something xsi:type="example:anything-something" a="baz" b="2" />
</somethings>

我想这是唯一的处理方式吗?如果是这样的话，这还不算太糟糕，而且 vs 智能感知似乎已经足够了解这一点了.

I guess this is the only way this is handled? if so this isn't so bad, and vs intellisense seems to understand this well enough.

谢谢.

推荐答案

这是个好问题.您可以执行一系列any"，这将允许您在内部任意命名元素 - 但这不会以任何方式限制它们.或者，下面的架构限制了名称和属性，但没有其他限制(如您的第二个示例)

This is a good question. You could do a sequence of "any", which would allow you have arbitrarily named elements inside - but that won't constrain them in any way. Alternately, the schema below constrains the name and the attributes, but nothing else (as in your second example)

<?xml version="1.0" encoding="ISO-8859-1" ?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">

  <xs:complexType name="somethingsType" >
    <xs:complexContent>    
      <xs:restriction base="xs:anyType">
       <xs:attribute name="a" type="xs:string"/>
       <xs:attribute name="b" type="xs:string"/>
      </xs:restriction>
    </xs:complexContent>
  </xs:complexType>

  <xs:complexType name="somethingsSeq" >
    <xs:sequence>
      <xs:element name="something" type="somethingsType"/>
    </xs:sequence>
  </xs:complexType>

  <xs:element name="somethings"  type="somethingsSeq"/> 

</xs:schema>

我找不到限制类型而不是元素名称的方法.

I can't find a way to constrain the type but not the element name.
