循环遍历动态 xml 树以将其展平

Question

我想制作一个样式表并使用 xslt/xpath 遍历我的树，但我无法用这个 xml 做基础。这 xml 适用于 xslt/xpath 吗？

我想通过 examId 遍历考试并检查 examType

<data>
    <map xmlns="http://www.w3.org/2005/xpath-functions">
        <string key="planCode">01267 COE-EN/2014-08-01</string>
        <string key="planName">01267 COE-EN</string>
        <map key="exams">
            <string key="examId">00131105</string>
            <string key="examType">Kwalificatie</string>
            <string key="examName">90404 S Interact. vormgev.</string>
            <array key="exams">
                <map>
                    <string key="examId">00162650</string>
                    <string key="examType">Kwalificatie</string>
                    <string key="examName">90402 S Interact. vormgev.</string>
                </map>
                <map>
                    <string key="examId">00162640</string>
                    <string key="examType">Kwalificatie</string>
                    <string key="examName">90403 S Interact. vormgev.</string>
                </map>
            </array>
        </map>
    </map>
</data>
        
XSLT for what its worth...
<xsl:stylesheet version="3.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:template match="/">
        <xsl:for-each select="/data/map/string/@key ">
            <test>Test</test>
        </xsl:for-each>
       </xsl:template>
</xsl:stylesheet>

Edit;
The answer helped me a lot and I could finally address the elements and attributes. I think it was because I didnt use the namespace xpath-default-namespace="http://www.w3.org/2005/xpath-functions"

给定地图元素上的命名空间声明，该路径仅在使用通配符 /data/*:map/*:string/@key 或声明例如xmlns:fn="http://www.w3.org/2005/xpath-functions" 在您的样式表中并使用例如/data/fn:map/fn:string/@key 或在样式表中声明 xpath-default-namespace="http://www.w3.org/2005/xpath-functions" 并使用 /*:data/map/string/@key 或 /*/map/string/@key.

要展平，请使用 //，如 /data//*:string[@key = 'examType']
