xml - 有没有办法在 schematron 中传递变量？

Question

我想使用一个变量来表示我的 schematron 断言并在我的验证消息中使用它。例如:

        <rule context="//Profile/User[@name]">
            <assert test="@name = ../business/@owner">User: '----' doesn't exist as a business owner. </assert>
        </rule>

'----' 是用户的名称。有没有办法在 schematron 中使用变量？

Answer 1

您可以使用 value-of 来检索变量或 XPath 的值:

    <rule context="//Profile/User[@name]">
        <assert test="@name = ../business/@owner">
          User: <value-of select="@name"/> doesn't exist as a business owner.
        </assert>
    </rule>

如果你想引入一个变量，使用let:

    <rule context="//Profile/User[@name]">
        <let name="userName" value="@name"/>
        <assert test="@name = ../business/@owner">
          User: <value-of select="$userName"/> doesn't exist as a business owner.
        </assert>
    </rule>
