根据其他属性值验证 XML 属性 [英] Validate XML attribute based on other attribute value

问题描述

我有以下 XML.

<?xml version="1.0" encoding="utf-8" ?>
<Items>
    <Item type="none" attNone1="test" attNone2="test3" />
    <Item type="action" attAction1="test" attAction2="test2" />
</Items>

我需要根据一些规则创建一个 XSD:

I need to create an XSD based on some rules:

1) 属性类型"是必需的.

1) the attribute "type" is required.

2) 如果属性值应该是none"或action"

2) If the attribute value should be "none" or "action"

3) 如果属性值为none"，我应该有另外两个必需的属性，attNone1"和attNone2".我不应该接受attAction1"或attAction2"

3) If the attribute value is "none" I should have two other required attribute, "attNone1" and "attNone2". I should not accept "attAction1" or "attAction2"

4) 如果属性值为action"，我应该有另外两个必需的属性，attAction1"和attAction2".我不应该接受attNone1"或attNone2"

4) If the attribute value is "action" I should have two other required attribute, "attAction1" and "attAction2". I should not accept "attNone1" or "attNone2"

知道如何执行此 XSD 吗?

Any idea how to do this XSD?

提前致谢，

问候，

推荐答案

XSD 1.0 不允许共现约束"，其中一个属性的类型取决于另一个属性的值.

XSD 1.0 does not allow "co-occurrence constraints" where the type of one attribute depends on the value of another.

在 XSD 1.1 中，您可以使用为此目的而发明的条件类型分配".Xerces 和 Saxon 目前支持 XSD 1.1.

In XSD 1.1 you can use "conditional type assignment" which was invented for this purpose. XSD 1.1 is currently supported in Xerces and Saxon.
