我正在使用 wkhtmltodpf 和 knp-snappy，我试图将 TOC 限制为最多 3 个孩子。我已经定义了如下所示的自定义 xsl 文件：

<xsl:template match="outline:outline">
    <html>
        <head>
        </head>
        <body>
            <h1>Table of Contents</h1>
            <ul><xsl:apply-templates select="outline:item/outline:item"/></ul>
        </body>
    </html>
</xsl:template>
<xsl:template match="outline:item">
    <li class="level-{count(ancestor::*) - 1}">
        <xsl:if test="((@title!='') and (@title!='Table of Contents'))">
            <div>
                <a>
                    <xsl:if test="@link">
                        <xsl:attribute name="href"><xsl:value-of select="@link"/></xsl:attribute>
                    </xsl:if>
                    <xsl:if test="@backLink">
                        <xsl:attribute name="name"><xsl:value-of select="@backLink"/></xsl:attribute>
                    </xsl:if>
                    <xsl:value-of select="@title" />
                </a>
                <span> <xsl:value-of select="@page" /> </span>
            </div>
        </xsl:if>
        <ul class="level-{count(ancestor::*) - 1}">
            <xsl:comment>added to prevent self-closing tags in QtXmlPatterns</xsl:comment>
            <xsl:apply-templates select="outline:item"/>
        </ul>
    </li>
</xsl:template>

并输出：
