XSLT根据层次结构级别添加表头

Question

这里是我的XML的一部分，表示术语的层次结构。TopTerm是最外层的父元素，ChildTerm是子元素，它可以有尽可能多的子元素。

<TopTerm ID="1" Entity="Term" Name="ENVIRONMENTAL MANAGEMENT">
    <ChildTerm Relationship="narrower" ID="8" Entity="Term" Name="Auditing">
        <ChildTerm Relationship="narrower" ID="36" Entity="Term" Name="Environmental audit" />
        <ChildTerm Relationship="narrower" ID="46" Entity="Term" Name="Type of audit []" />
    </ChildTerm>
    <ChildTerm Relationship="narrower" ID="11" Entity="Term" Name="Incidents">
        <ChildTerm Relationship="narrower" ID="71" Entity="Term" Name="Bruce Beresford" />
        <ChildTerm Relationship="narrower" ID="35" Entity="Term" Name="Case name" />
        <ChildTerm Relationship="narrower" ID="83" Entity="Term" Name="Jack Lemmon" />
        <ChildTerm Relationship="narrower" ID="87" Entity="Term" Name="Mary Pcikford" />
    </ChildTerm>
    <ChildTerm Relationship="narrower" ID="16" Entity="Term" Name="Monitoring" />
    <ChildTerm Relationship="narrower" ID="18" Entity="Term" Name="Policies and procedures" />
</TopTerm>

我想要一个带有表的XSLT 1.0 HTML输出，结果应该如下所示

<table>
   <tr>
     <th>Level 1</th>
     <th>Level 2</th>
     <th>Level 3</th>
     <th>Level 4</th>   
   </tr>
   <tr>
     <td>ENVIRONMENTAL MANAGEMENT</td>
     <td>Auditing</td>
     <td>Environmental audit</td>
   </tr>
</table>

差不多。我的问题是我不知道这个层次结构的深度来添加适当的<th>Level x</th>，其中x可以是基于深度的任何数字。术语级别应该与表标题匹配。

好吧，你只需要抓住最深的那个，然后迭代它的祖先。试试这样:

XSLT 1.0

<?xml version="1.0" encoding="UTF-8"?>
<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:template match="TopTerm">
    <table border="1">
        <thead>
            <xsl:apply-templates select="descendant::ChildTerm[not(*)]" mode="header">
                <xsl:sort select="count(ancestor-or-self::*)" data-type="number" order="descending"/>
            </xsl:apply-templates>
        </thead>
        <tbody>
            <xsl:apply-templates select="descendant::ChildTerm[not(*)]"/>
        </tbody>
    </table>
</xsl:template>
<xsl:template match="ChildTerm" mode="header">
    <xsl:if test="position()=1">
        <tr>
            <xsl:for-each select="ancestor-or-self::*">
                <th><xsl:value-of select="concat('Level ', position())"/></th>
            </xsl:for-each>
        </tr>
    </xsl:if>
</xsl:template>
<xsl:template match="ChildTerm">
    <tr>
        <xsl:for-each select="ancestor-or-self::*">
            <td><xsl:value-of select="@Name"/></td>
        </xsl:for-each>
    </tr>
</xsl:template>
</xsl:stylesheet>
