XSLT统计<th>数量生成对应radio输入框的问题求助

编写XSLT代码时，需要统计生成的标签数量，以此确定要创建多少个输入框。尝试创建变量set但遇到作用域问题，求其他实现方法。

当前使用的XSLT代码 #

<xsl:for-each select="MeetingPollingParts/MeetingPollingParts">
   <table class="table" style="width:100%;border-color:gray">
   <xsl:choose>
       <xsl:when test="MeetingPollingPartsTypeId = 3">
           <thead>
             <tr>
               <xsl:for-each select="MeetingPollingPartsValues/MeetingPollingPartsValues">
                 <xsl:variable name="set" select="MeetingPollingPartsValues/MeetingPollingPartsValues" />
               
                 <th>
                   <xsl:value-of select="QuestionValue" disable-output-escaping="yes"/>
                 </th>
               </xsl:for-each>
             </tr>
           </thead>
       </xsl:when>
       <xsl:when test="MeetingPollingPartsTypeId = 5">
         <tbody>
               <xsl:for-each select="MeetingPollingPartsValues/MeetingPollingPartsValues">
                 <tr>
                   <td style="padding: 8px;line-height: 1.42857143;vertical-align: top;border-top: 1px solid #ddd;">
                     <xsl:value-of select="QuestionValue" disable-output-escaping="yes"/>
                   </td>
                   <td style="padding: 8px;line-height: 1.42857143;vertical-align: top;border-top: 1px solid #ddd;">
                     <input type="radio"></input>
                   </td>
                 </tr>
               </xsl:for-each>
           </tbody>
       </xsl:when>
   </xsl:choose>
   </table>
 </xsl:for-each>

当前输出 #

当前会生成两个独立的表格：一个仅包含表头（有Yes、No、Abstain三个<th>标签），另一个仅包含表体（每行只有一个<input type="radio">输入框），无法形成期望的合并表格结构。

期望HTML输出 #

<table class="table">
  <thead>
    <tr>
      <th/>
      <th>Yes</th>
      <th>No</th>
      <th>Abstain</th>
    </tr>
  </thead>
  <tbody>
    <tr>
      <td class="bold">Row 1</td>
      <td>
        <input type="radio"/>
      </td>
      <td>
        <input type="radio"/>
      </td>
      <td>
        <input type="radio"/>
      </td>
    </tr>
    <tr>
      <td class="bold">Row 3</td>
      <td>
        <input type="radio"/>
      </td>
      <td>
        <input type="radio"/>
      </td>
      <td>
        <input type="radio"/>
      </td>
    </tr>
  </tbody>
</table>

解决方案 #

核心思路是不要循环每个MeetingPollingParts生成独立表格，而是在同一个表格内，先获取表头数据的选项集合，再基于这个集合生成表头和对应数量的radio输入框。

修改后的XSLT代码如下：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output method="html" indent="yes"/>

  <xsl:template match="MeetingPollingQuestion">
    <!-- 定义变量存储表头的选项节点集合 -->
    <xsl:variable name="header-options" select="MeetingPollingParts/MeetingPollingParts[MeetingPollingPartsTypeId=3]/MeetingPollingPartsValues/MeetingPollingPartsValues"/>
    
    <table class="table">
      <!-- 生成表头 -->
      <thead>
        <tr>
          <!-- 空的表头单元格 -->
          <th/>
          <!-- 循环表头选项生成<th> -->
          <xsl:for-each select="$header-options">
            <th>
              <xsl:value-of select="QuestionValue"/>
            </th>
          </xsl:for-each>
        </tr>
      </thead>
      
      <!-- 生成表体 -->
      <tbody>
        <xsl:for-each select="MeetingPollingParts/MeetingPollingParts[MeetingPollingPartsTypeId=5]/MeetingPollingPartsValues/MeetingPollingPartsValues">
          <tr>
            <!-- 行名称单元格 -->
            <td class="bold">
              <xsl:value-of select="QuestionValue"/>
            </td>
            <!-- 基于表头选项数量循环生成radio输入框 -->
            <xsl:for-each select="$header-options">
              <td>
                <input type="radio"/>
              </td>
            </xsl:for-each>
          </tr>
        </xsl:for-each>
      </tbody>
    </table>
  </xsl:template>
</xsl:stylesheet>

关键说明： #

1. 变量作用域解决：将$header-options变量定义在根模板内，作用域覆盖整个表格的表头和表体生成逻辑，避免局部变量无法跨模块访问的问题。
2. 统一表格结构：不再为每个MeetingPollingParts单独创建表格，而是在一个表格内整合表头和表体，符合期望的HTML结构。
3. 动态匹配数量：通过循环$header-options集合，自动生成与表头数量一致的radio输入框，无需手动统计数量。
