请注意，发生两次的事件在该事件中进行排序，但不会与所有其他事件进行排序。 在给定XML结构的情况下，是否有方法对其进行排序

我一直在使用这个在线工具来测试我的XSLT

预期结果应该是这样的

结果完全排序。

这里的问题是，您正在对评论元素进行排序，但在评论元素中有多个评论元素，您只在第一个日期对评论元素进行排序

这里不需要为每个语句使用两个xsl:for。您可以直接迭代子comment元素，这将解决排序问题

<xsl:for-each select="FormComments/Comments/Comment">
在迭代子Comment元素之前，您似乎想先访问Comments元素的eventName属性。这仍然是可以实现的，只要在注释元素上使用父选择器即可

<xsl:value-of select="../@EventName"/>
尝试以下XSLT

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

            <xsl:for-each select="FormComments/Comments/Comment"><!-- Sort by year -->
                <xsl:sort select="substring-before(substring-after(substring-after(DateTime,'/'),'/'),' ')"/><!-- Sort by Month -->
