如何在 Schematron 中将命名空间和路径组合到元素中？

Question

我可以正确验证这个 XML 文件

<?xml version='1.0' encoding='UTF-8'?>
<world>
    <dog>
        <ears DIRTY='no'>
        </ears>
    </dog>
    <human>
        <ears EARRING='yes'>
        </ears>
    </human>
</world>

使用此架构

<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns="http://purl.oclc.org/dsdl/schematron">
    <pattern>
        <rule context='world/human/ears'>
            <assert test="@EARRING">ears element in human must have EARRING attribute</assert>
        </rule>
        <rule context='world/dog/ears'>
            <assert test="@DIRTY">ears element in dog must have DIRTY attribute</assert>
        </rule>
    </pattern>
</schema>

但是当我引入默认命名空间时无法正确验证它。

例如，将其作为 XML 文件：

<?xml version='1.0' encoding='UTF-8'?>
<world xmlns='default-namespace'>
    <dog>
        <ears DIRTY='no'>
        </ears>
    </dog>
    <human>
        <ears EARRING='yes'>
        </ears>
    </human>
</world>

这是模式：

<?xml version="1.0" encoding="UTF-8"?>
<schema xmlns="http://purl.oclc.org/dsdl/schematron">
    <ns prefix="mets" uri="default-namespace"/>
    <pattern>
        <rule context='mets:world/human/ears'>
            <assert test="@COLOR">ears element in human must have COLOR attribute</assert>
        </rule>
        <rule context='mets:world/dog/ears'>
            <assert test="@DIRTY">ears element in dog must have DIRTY attribute</assert>
        </rule>
    </pattern>
</schema>

它应该会失败（@COLOR 缺失），但它不会。

我做错了什么？

Answer 1

每个元素都需要有命名空间前缀。变化：

<rule context='mets:world/human/ears'>

至：

<rule context='mets:world/mets:human/mets:ears'>
