我正在使用XSL列出出现在LHS导航列表上的XML上的页面和子页面。我需要tree/page/page[2]/page[2]/name路径下的所有网页名称。
不确定在纠正错误方面是否错误。
目前仅显示第一级页面。
<xsl:template match="/">
<textarea><xsl:copy-of select="*"/></textarea>
<div class="BOXContentPane nopadd-BOXContentPane clearfix">
<ul id="nav-main" class="navigation qnav">
<xsl:apply-templates select="//tree/page/page"/>
</ul>
</div>
</xsl:template>
<xsl:template match="page">
<li>
<xsl:attribute name="class">
<xsl:choose>
<xsl:when test="current_page">link active</xsl:when>
<xsl:otherwise>link</xsl:otherwise>
</xsl:choose>
</xsl:attribute>
<a href="{href}" title="{title}">
<xsl:if test="@current_page='true' or current_page_ancestor">
<xsl:attribute name="class">active</xsl:attribute>
</xsl:if>
<xsl:value-of select="name" disable-output-escaping="yes"/>
</a>
</li>
</xsl:template>
</xsl:stylesheet>
@Tim C：
感谢您的回复。预期的输出是我需要在decendant_level =“1”页面下显示decendant_level =“2”页面。截至目前，只有所有decendant_level =“1”页面都显示在LHS菜单上。
输入XML：

答案 0 :(得分：1)
看起来您只需要添加一行来递归调用现有的“页面”模板。
您可以在关闭 li 标记之前添加此声明。
<xsl:if test="page[@decendant_level='2']">
<ul id="nav-main" class="navigation qnav">
<xsl:apply-templates select="page"/>
</ul>
</xsl:if>
因此，这会检查是否有任何页面元素，其中decendant_level设置为“2”，如果是，则启动新列表。
试试这个XSLT
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output omit-xml-declaration="yes" indent="yes" />
<xsl:template match="/">
<div class="BOXContentPane nopadd-BOXContentPane clearfix">
<ul id="nav-main" class="navigation qnav">
<xsl:apply-templates select="//tree/page/page"/>
</ul>
</div>
</xsl:template>
<xsl:template match="page">
<li>
<xsl:attribute name="class">
<xsl:choose>
<xsl:when test="current_page">link active</xsl:when>
<xsl:otherwise>link</xsl:otherwise>
</xsl:choose>
</xsl:attribute>
<a href="{href}" title="{title}">
<xsl:if test="@current_page='true' or current_page_ancestor">
<xsl:attribute name="class">active</xsl:attribute>
</xsl:if>
<xsl:value-of select="name" disable-output-escaping="yes"/>
</a>
<xsl:if test="page[@decendant_level='2']">
<ul id="nav-main" class="navigation qnav">
<xsl:apply-templates select="page"/>
</ul>
</xsl:if>
</li>
</xsl:template>
</xsl:stylesheet>
