我知道问题可能出在xsl文件中。我不是专家，我会非常乐意帮助你。
这是xsl文件。
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:key name="hatchala" match="/TVGuide/Channel/Program" use="Start"/>
<xsl:template match="/">
<table border="1">
<tr>hours
<xsl:call-template name="tvchan"/>
</tr>
<tr>
<th>
<xsl:call-template name="hour"/>
</th>
</tr>
</table>
</xsl:template>
<xsl:template name="tvchan">
<xsl:for-each select="/TVGuide/Channel">
<th>
<td>
<xsl:value-of select ="Name"/>
</td>
</th>
</xsl:for-each>
</xsl:template>
<xsl:template name="hour">
<xsl:for-each select="/TVGuide/Channel/Program[not(./Start=following::Start)]">
<xsl:sort select="Start"/>
<xsl:variable name="zman" select ="Start"/>
<tr>
<td>
<xsl:value-of select="Start"/>
</td>
<xsl:for-each select="/TVGuide/Channel/Program[Start=$zman]">
<xsl:variable name="name1">
<xsl:choose>
<xsl:when test="Title!=''">
<xsl:value-of select="Title"/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="Series"/>
</xsl:otherwise>
</xsl:choose>
</xsl:variable>
<td>
<xsl:value-of select="$name1"/>
</td>
</xsl:for-each>
</tr>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
结果应显示包含所有程序及其小时数的表格。

非常感谢你的帮助。
答案 0 :(得分：2)
首先，如果您使用的是XSLT1.0，则可以使用称为Muenchian Grouping的技术来获取所有程序的不同开始时间。这包括设置一个按键，通过start元素查找程序。
<xsl:key name="hatchala" match="Program" use="Start"/>
请注意，您不一定需要 Program 元素的完整Xpath，因为该键会在任何级别查找它们（如果您在不同级别拥有此类元素，则只能量化事物，并希望限制它们。）
然后，为了获得不同的开始时间，你会查找恰好是关键字中该元素首次出现的程序的开始时间
<xsl:apply-templates
select="/TVGuide/Channel/Program
[generate-id() = generate-id(key('hatchala', Start)[1])]" mode="header">
（'mode'的使用很快就会明确，因为最终的XSLT会多次匹配 Program 元素。）
我还会定义一个键，用于在给定的开始时间内查找给定频道的节目
<xsl:key name="hatchala2" match="Program" use="concat(../Name, '|', Start)"/>
然后，对于给定的开始时间，你会循环遍历所有通道，如此......
<xsl:apply-templates select="/TVGuide/Channel" mode="program">
<xsl:with-param name="Start" select="Start"/>
</xsl:apply-templates>
然后模板匹配，可以使用键
查找程序<xsl:template match="Channel" mode="program">
<xsl:param name="Start"/>
<td>
<xsl:apply-templates select="key('hatchala2', concat(Name, '|', $Start))" mode="program"/>
</td>
</xsl:template>
这是完整的XSLT
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="html" indent="yes"/>
<xsl:key name="hatchala" match="Program" use="Start"/>
<xsl:key name="hatchala2" match="Program" use="concat(../Name, '|', Start)"/>
<xsl:template match="/TVGuide">
<table border="1">
<tr>
<th>hours</th>
<xsl:apply-templates select="Channel" mode="header"/>
</tr>
<tr>
<th>
<xsl:apply-templates select="/TVGuide/Channel/Program[generate-id() = generate-id(key('hatchala', Start)[1])]" mode="header">
<xsl:sort select="Start"/>
</xsl:apply-templates>
</th>
</tr>
</table>
</xsl:template>
<xsl:template match="Channel" mode="header">
<th>
<xsl:value-of select="Name"/>
</th>
</xsl:template>
<xsl:template match="Program" mode="header">
<tr>
<td>
<xsl:value-of select="Start"/>
</td>
<xsl:apply-templates select="/TVGuide/Channel" mode="program">
<xsl:with-param name="Start" select="Start"/>
</xsl:apply-templates>
</tr>
</xsl:template>
<xsl:template match="Channel" mode="program">
<xsl:param name="Start"/>
<td>
<xsl:apply-templates select="key('hatchala2', concat(Name, '|', $Start))" mode="program"/>
</td>
</xsl:template>
<xsl:template match="Program" mode="program">
<xsl:choose>
<xsl:when test="Title!=''">
<xsl:value-of select="Title"/>
</xsl:when>
<xsl:otherwise>
<xsl:value-of select="Series"/>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
然后输出以下内容
<table border="1">
<tr>
<th>hours</th>
<th>BBC1</th>
<th>BBC2</th>
<th>ITV</th>
<th>Channel 4</th>
<th>Channel 5</th>
</tr>
<tr>
<th>
<tr>
<td>2001-07-05T19:00:00</td>

请注意使用 xsl：apply-templates 而不是 xsl：for-each 以避免过多的嵌套代码，以尝试使其更易于阅读。
如果您想要一个主要使用 xsl：for-each 的版本，请尝试使用此XSLT
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="html" indent="yes"/>
<xsl:key name="hatchala" match="Program" use="Start"/>
<xsl:key name="hatchala2" match="Program" use="concat(../Name, '|', Start)"/>
<xsl:template match="/TVGuide">
<table border="1">
<tr>
<th>hours</th>
<xsl:for-each select="Channel">
<th>
<xsl:value-of select="Name"/>
</th>
</xsl:for-each>
</tr>
<tr>
<th>
<xsl:for-each select="/TVGuide/Channel/Program[generate-id() = generate-id(key('hatchala', Start)[1])]">
<xsl:sort select="Start"/>
<xsl:variable name="Start" select="Start" />
<tr>
<td>
<xsl:value-of select="$Start"/>
</td>
<xsl:for-each select="/TVGuide/Channel">
<td>
<xsl:apply-templates select="key('hatchala2', concat(Name, '|', $Start))" />
</td>
</xsl:for-each>
</tr>
</xsl:for-each>
</th>
</tr>
</table>
</xsl:template>
<xsl:template match="Program">
<xsl:value-of select="Series"/>
</xsl:template>
<xsl:template match="Program[Title!='']">
<xsl:value-of select="Title"/>
</xsl:template>
</xsl:stylesheet>
这应该生成相同的输出。请注意，我已经留下了一个 xsl：apply-templates ，因为它可以产生模式匹配的好处，并提供 xsl：choose 的替代方案。
