我的XSLT-Stylesheet有问题。我有一个包含多个程序集的XML文档。每个组件都有一个唯一的项目编号。程序集可以包含其他程序集作为位置，但XML文档具有如下平面结构：
<?xml version="1.0" encoding="ISO-8859-1"?>

识别子装配的唯一方法是项目编号。 我想使用jsTree jquery插件将XML显示为树结构。 因此我需要一个像这样的HTML输出：
<div id="jsTree">
<ul>
<li>0001 | Main assembly
<ul>
<li>1111 | Sub assembly 1</li>
<li>2222 | Sub assembly 2</li>
<li>3333 | Sub assembly 3</li>
</ul>
</li>
</ul>
</div>
到目前为止，我尝试使用与我的问题类似的许多问题的答案，但没有任何效果。谁能帮我？提前谢谢！

您需要使用键，以便每个程序集都可以（递归地）将模板应用于其组件：
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform" >
<xsl:output method="xml" version="1.0" encoding="utf-8" indent="yes"/>
<xsl:key name="kAssy" match="Assembly" use="@Item" />
<xsl:template match="/PartsCatalog">
<div id="jsTree">
<ul>
<xsl:apply-templates select="Assembly[Description='Main assembly']"/>
</ul>
</div>
</xsl:template>
<xsl:template match="Assembly">
<li>
<xsl:value-of select="@Item"/>
<xsl:text> | </xsl:text>
<xsl:value-of select="Description"/>
<xsl:variable name="mySubs" select="key('kAssy', Position/@Item)" />
<xsl:if test="$mySubs">
<ul>
<xsl:apply-templates select="$mySubs"/>
</ul>
</xsl:if>
</li>
</xsl:template>
</xsl:stylesheet>
答案 1 :(得分：0)
基本答案是你需要以正常的方式使用xsl：apply-templates通过数据进行自上而下的递归下降，但有一个例外：而不是处理XML树中节点的物理子节点，你需要处理它的逻辑孩子。所以不要写
<xsl:apply-templates select="child::node()"/>
<xsl:apply-templates select="//Assembly[@Item = current()/Position/@Item]"/>
然后下一个阶段就是你可以使用密钥来优化它，如michael.hor257k所描述的（如果你使用像Saxon-EE这样自动进行优化的处理器，则不需要）。
