查看此处的工作情况：要找到您可以使用的最大代码元素：max（root/object/data/zordadeindicatedinformation/zordaClassification/code）我需要找到最大级别，并获取关联代码的值是否有联系？如果是，结果应该是什么？平局是什么意思？两个或多个具有相同级别的代码。这正是我需要的输出，但当我在xslt中使用时，它不起作用…您的xslt引擎支持xslt 2.0或更高版本吗？你用的是哪种发动机？max（）在XPath/XSLT 1中不可用。您的代码可以工作，但如果我有多个/data/I，我只有position（）=1的第一行，并且我需要x行…@soufiane请参阅我上面的答案（XSLT 1.0解决方案）中的更新。您以非常优雅的方式完成了：）
