我想构建我的html报告，以便按如下方式处理我的XML。我正在努力把语法弄对。我可以在一个变量中获得外部的cf_fixinpatch值，但不能在"select"中使用该值来进一步过滤。我知道我有什么记录。。。感谢
输出Html
<html>
<cf_fixinpatch> <= loop through unique values
write cf_fixinpatch header
<section> <= loop through unique values
write section header
<All records matching cf_fixinpatch and section values> <= loop
Write out various aspects of the Result node
</section>
<cf_fixinpatch>
</html>
输入XML
<DocumentElement>
<Results> <= many repeat nodes
<bug_id>64252</bug_id>
<name>SCADA</name>
<short_desc>[FUNCTIONALITY]: Server name is not correct in SOE System Message</short_desc>
<bug_status>VERIFIED</bug_status>
<resolution>FIXED</resolution>
<bug_severity>normal</bug_severity>
<section>Alarms</section>
<release_title>Some SOE items that reference an alarm server do not use its proper name</release_title>
<release_notes>Such events now use "ClusterName_ServerName" when referencing alarm servers.</release_notes>
<cf_fixinpatch>v7.50 SP1 Patch 5</cf_fixinpatch>
</Results>
...
</DocumentElement>
注意：使用不支持2.0的Windowsmsxl（如果太难，可以转到2.0），我可以做一些类似的事情
<xsl:variable name="unique-list" select="/DocumentElement/Results[not(cf_fixinpatch=following::Results/cf_fixinpatch)]" />
<xsl:for-each select="$unique-list">
<xsl:variable name="current_patch" select="cf_fixinpatch" />
<!-- but don't know how to use this in the next loop -->
-----------------
<xsl:for-each select="/DocumentElement/Results">
<xsl:if test="not(section = preceding-sibling::section)"> <= cant get to work, if worked i can win or
<xsl:if test="cf_fixinpatch != Results[position()-1]/cf_fixinpatch">
PM 09/05反馈-我找到了一个解决方案，但这是很难做到的，所以我提供了一些反馈
<xsl:for-each select="/DocumentElement/Results">
<xsl:variable name="thePatch" select="preceding-sibling::Results[1]/cf_fixinpatch"></xsl:variable>
<xsl:if test="($Patches = 'true') and (position() = 1 or cf_fixinpatch != $thePatch)">
<!-- Write out the Patch Level -->
<h4 style="color:#d82553">
<a>
<xsl:value-of select="cf_fixinpatch" />
</a>
</h4>
</xsl:if>
<xsl:variable name="theSection" select="preceding-sibling::Results[1]/section"></xsl:variable>
<xsl:if test="(position() = 1) or (section != $theSection)">
<!-- Write out the Section Information -->
<h4 style="color:#C75B12;text-index:40px">
<a>
<xsl:value-of select="section" />
</a>
</h4>
</xsl:if>
<!-- Then record info written out -->
看起来您正在将Results元素首先按cf_fixinpatch分组，然后，对于同一补丁中的所有元素，按section元素分组。这意味着您要进行两次分组。要按cf_fixinpatch分组，您需要此密钥
<xsl:key name="results_by_patch" match="Results" use="cf_fixinpatch" />
但是，要对给定组中所有Results元素的section值进行分组（而不是文档中的所有Results），您需要一个级联密钥
<xsl:key name="results_by_patch_and_section" match="Results" use="concat(cf_fixinpatch, '|', section)" />
试试这个XSLT，它将一个Muenchian分组嵌套在另一个分组中：
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" indent="yes" />
<xsl:key name="results_by_patch" match="Results" use="cf_fixinpatch" />
<xsl:key name="results_by_patch_and_section" match="Results" use="concat(cf_fixinpatch, '|', section)" />
<xsl:template match="DocumentElement">
<html>
<body>
<xsl:for-each select="Results[generate-id() = generate-id(key('results_by_patch', cf_fixinpatch)[1])]">
<h1 style="color:#d82553">
<xsl:value-of select="cf_fixinpatch" />
</h1>
<xsl:for-each select="key('results_by_patch', cf_fixinpatch)[generate-id() = generate-id(key('results_by_patch_and_section', concat(cf_fixinpatch, '|', section))[1])]">
<h2 style="color:#C75B12;text-index:40px">
<xsl:value-of select="section" />
</h2>
<xsl:apply-templates select="key('results_by_patch_and_section', concat(cf_fixinpatch, '|', section))" />
</xsl:for-each>
</xsl:for-each>
</body>
</html>
</xsl:template>
<xsl:template match="Results">
<div>
<xsl:value-of select="bug_id" />
</div>
</xsl:template>
</xsl:stylesheet>
