在 xsd:all 中具有 xsd:sequence 行为的替代方法是什么? [英] What is the alternative to have xsd:sequence behavior inside a xsd:all?

问题描述

我不明白我应该如何定义我的复杂类型.

I don't understand how I should define my complex type.

今天我有这个:

<xsd:element name="batch_requests_callbacks">
    <xsd:complexType>
      <xsd:sequence>
            <xsd:element ref="document_id" minOccurs="1" maxOccurs="1"/>
            <xsd:choice minOccurs="0" maxOccurs="1">
              <xsd:element ref="filename"/>
              <xsd:element ref="error"/>
            </xsd:choice>
            <xsd:element ref="author" minOccurs="0" maxOccurs="unbounded"/>
      </xsd:sequence>
      <xsd:attribute name="version" default="1.0"/>
    </xsd:complexType>
</xsd:element>

但是，xsd:sequence 中标签的顺序很重要，我不希望出现这种行为.

But then, the tag's order inside the xsd:sequence is important and I don't want that behavior.

如果我使用 xsd:all 我没有标签顺序但我不能将 maxOccurs 设置为 unbounded more 我不能使用 xsd:choice 在 xsd:all

If I use xsd:all I don't have the tag order but I cannot set maxOccurs to unbounded more over I cannot use xsd:choice inside a xsd:all

我有哪些选择?

推荐答案

您可以使用 代替您的 xsd:sequence 以模拟无序元素验证.这绕过了 xsd:all 的限制.

You can use <xsd:choice minOccurs="0" maxOccurs="unbounded"> instead of your xsd:sequence in order to emulate non-ordered element validation. This circumvents the limitations of xsd:all.
