我正在尝试按日期和时间对xml进行排序

我想出了这个

}

font-size:20pt;

</STYLE>
<hr />
<table cellpadding='8' border='1'>

问题是它只在Comments节点内排序，而不是在所有Comments节点上排序。
我不能发照片，因为我刚注册了这个网站…输出看起来像

注意，发生两次的事件在该事件中排序，而不是与所有其他事件排序。在给定XML结构的情况下，是否存在排序方法?
我一直在使用这个在线工具测试我的XSLThttp://www.w3schools.com/xsl/tryxslt.asp?xmlfile=cdcatalog& xsltfile = cdcatalog
预期结果如下

结果完全排序…
这里的问题是，您正在排序comments元素，但是在comments元素中有多个comment元素，并且您仅按第一个日期排序comments元素。
这里并不需要两个xsl:for-each语句。您可以直接遍历注释子元素，这将解决排序问题。<xsl:for-each select="FormComments/Comments/Comment">
看起来您想先访问Comments元素的eventName属性，然后再遍历子Comment元素。这仍然是可以实现的，只要在注释元素
上使用父选择器<xsl:value-of select="../@EventName"/>
尝试下面的XSLT
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<table>
<th>Event</th>
<th>Approver</th>
<th>Action</th>
<th>Comment</th>
<th>Time</th>
<xsl:for-each select="FormComments/Comments/Comment"><!-- Sort by year -->
<xsl:sort select="substring-before(substring-after(substring-after(DateTime,'/'),'/'),' ')"/><!-- Sort by Month -->
<xsl:sort select="substring(normalize-space(DateTime),1,2)"/><!-- Sort by AM / PM -->
<xsl:sort select="substring-after(substring-after(normalize-space(DateTime), ' '),' ')"/><!-- Sort by hour -->
<xsl:sort select="substring-before(substring-after(substring-after(DateTime,' '),' '),':')"/><!-- Sort by minute -->
<xsl:sort select="substring-before(substring-after(normalize-space(DateTime), ':'),' ')"/>
<xsl:variable name="User">
<xsl:value-of select="UserName"/>
</xsl:variable>
<tr>
<td>
<xsl:value-of select="../@EventName"/>
</td>
<td>
<xsl:value-of select="substring($User,8)"/>
</td>
<td class="Center">
<xsl:value-of select="Action"/>
</td>
<td>
<xsl:value-of select="Body"/>
</td>
<td>
<xsl:value-of select="DateTime"/>
</td>
</tr>
</xsl:for-each>
</table>
</xsl:template>
</xsl:stylesheet>
(为了简洁，我剪掉了几行)
应用于XML时，输出如下
<table>
<th>Event</th>
<th>Approver</th>
<th>Action</th>
<th>Comment</th>
<th>Time</th>
<tr>
<td>Position Clearance</td>
<td>userId</td>
<td class="Center">Clearance Obtained</td>
<td>Clearance is obtained</td>
