Question

我需要在应用xsl：fo的嵌套列表中使用带连字符的连字符。我有两个匹配的模板，但只有一个被应用。如果我只使用第一个模板，则外部列表会应用模板。如果我只使用第二个模板，嵌套列表将应用模板。我试图在第二个模板中匹配的模式是任何无序列表，列表项作为父项。非常感谢任何有关获得所需输出的帮助。

XML

<ThisNode>
<ul>
    <li>Item One</li>
    <li>Item Two</li>
    <li>Item Three
        <ul>
            <li>Sub-Item One</li>
            <li>Sub-Item Two</li>
        </ul>
    </li>
    <li>Item Four</li>
    <li>Item Five</li>
</ul>
</ThisNode>

XSLT

<xsl:template match="ul">
<fo:list-block>
    <xsl:for-each select="./li">
        <fo:list-item>
            <fo:list-item-label end-indent="label-end()">
                <fo:block font-weight="bold">•</fo:block>
            </fo:list-item-label>
            <fo:list-item-body start-indent="8pt">
                <fo:block><xsl:value-of select="."/></fo:block>
            </fo:list-item-body>
        </fo:list-item>
    </xsl:for-each>
</fo:list-block>
</xsl:template>

<xsl:template match="li//ul">
<fo:list-block start-indent="8pt">
    <xsl:for-each select="./li">
        <fo:list-item>
            <fo:list-item-label end-indent="label-end()">

        </fo:list-item>
    </xsl:for-each>
</fo:list-block>
</xsl:template>

<fo:block text-align="left">
    <xsl:apply-templates select="./ThisNode"/>
</fo:block>

渴望输出

• Item One
• Item Two
• Item Three
    - Sub-Item One
    - Sub-Item Two
• Item Four
• Item Five

仅使用第一次模板或同时使用的实际输出

• Item One
• Item Two
• Item ThreeSub-Item OneSub-Item Two
• Item Four
• Item Five

仅使用第二个模板进行实际输出

Item One Item Two Item Three
    - Sub-Item One
    - Sub-Item Two
Item Four Item Five

Answer 1

这似乎是call-template mode的好地方，可以区分这两种情况。外部模板调用内部模板：

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fo="http://www.w3.org/1999/XSL/Format">

   <xsl:template match="/">
      <fo:block text-align="left">
         <xsl:apply-templates select="ThisNode"/>
      </fo:block>
   </xsl:template>


   <xsl:template match="ul">
      <fo:list-block>
         <xsl:for-each select="li">
            <fo:list-item>
               <fo:list-item-label end-indent="label-end()">
                  <fo:block font-weight="bold">•</fo:block>
               </fo:list-item-label>
               <fo:list-item-body start-indent="8pt">
                  <fo:block>
                     <!-- I'm not quite sure what you want here -->
                     <xsl:value-of select="text()"/>
                     <xsl:apply-templates select="ul" mode="inner"/>
                  </fo:block>
               </fo:list-item-body>
            </fo:list-item>
         </xsl:for-each>
      </fo:list-block>
   </xsl:template>

   <xsl:template match="ul" mode="inner">
      <fo:list-block start-indent="8pt">
         <xsl:for-each select="./li">
            <fo:list-item>
               <fo:list-item-label end-indent="label-end()">
                  <fo:block font-weight="bold">-</fo:block>
               </fo:list-item-label>
               <fo:list-item-body start-indent="16pt">
                  <fo:block>
                     <xsl:value-of select="."/>
                  </fo:block>
               </fo:list-item-body>
            </fo:list-item>
         </xsl:for-each>
      </fo:list-block>
   </xsl:template>

</xsl:stylesheet>

Answer 2

以下样式表说明了可能的解决方案。您的方法并不遥远 - 但是，它无法解释XSLT处理器的行为。这个表达式：

<xsl:value-of select="."/>

默认返回作为上下文节点的子节点的任何文本节点。但在您的情况下（li元素的模板匹配），所有后代文本节点都会输出，而不仅仅是li的直接子节点。

因此，下面的样式表使用

<xsl:value-of select="child::text()"/>

检索li元素的文本内容，然后<xsl:apply-templates>处理作为其子项的任何li元素。

正如你的标题所述，

xsl：fo模板匹配未在嵌套列表中触发

您正确诊断了它。这是因为 - 一旦在模板中匹配li - 您就不会让XSLT处理器处理后代li元素。
