XSLT分组依据+；基于多个标记级别的计数 但问题并不完全相同，因为我的密钥是复合的，但来自多个XML标记

我的XSL：

<result>
    <account id="123456">
        <missing_data missing_in="Archimede"/>
            <line_not_found db_table="PRODUCT" id="PDT">
            </line_not_found>
            <line_not_found db_table="ADRESS" id="ADR">
            </line_not_found>
        </missing_data>
        <missing_data missing_in="Cassiope">
            <line_not_found db_table="PRODUCT" id="PDT">
            </line_not_found>
            <line_not_found db_table="PRODUCT" id="PDT">
            </line_not_found>
            <line_not_found db_table="ADRESS" id="ADR">
            </line_not_found>
            <line_not_found db_table="ADRESS" id="ADR">
            </line_not_found>
            <line_not_found db_table="ADRESS" id="ADR">
            </line_not_found>
            <line_not_found db_table="ADRESS" id="ADR">
            </line_not_found>
        </missing_data>
    </account>
</result>

此项目必须使用XSLT 1

提前感谢

因为您在XSLT 1.0中对元素进行分组，所以您必须使用Muenchian分组来实现您想要做的事情：

<?xml version="1.0" encoding="UTF-8"?>
