XSLT分组特定的兄弟姐妹

Question

我现在正在XSLT 1.0工作，我在正确分组时遇到了麻烦。我的XML无法更改，看起来像：

<Analysis>
  <comment>Test 1</comment>
  <Action>
    <Result>Passed</Result>
  </Action>
  <Action>
    <Result>Passed</Result>
  </Action>
  <Action>
    <Result>Passed</Result>
  </Action>
  <comment>Start 2nd Phase</comment>
  <Action>
    <Result>Failed</Result>
  </Action>
  <Action>
    <Result>Passed</Result>
  </Action>
  <comment>Test 2</comment>
  <Action>
    <Result>Failed</Result>
  </Action>
  <Action>
    <Result>Failed</Result>
  </Action>
  <Action>
    <Result>Passed</Result>
  </Action>
  <comment>Start 2nd Phase</comment>
  <Action>
    <Result>Failed</Result>
  </Action>
  <comment>Start 3rd Phase</comment>
  <Action>
    <Result>Failed</Result>
  </Action>
  <comment>Test 3</comment>
  <Action>
    <Result>Passed</Result>
  </Action>
  <Action>
    <Result>Passed</Result>
  </Action>
  <Action>
    <Result>Passed</Result>
  </Action>
  <Action>
    <Result>Passed</Result>
  </Action>
  <Action>
    <Result>Passed</Result>
  </Action>
  <comment>Test 4</comment>
  <Action>
    <Result>Failed</Result>
  </Action>
  <Action>
    <Result>Failed</Result>
  </Action>
  <Action>
    <Result>Passed</Result>
  </Action>
  <comment>Start 2nd Phase</comment>
  <Action>
    <Result>Failed</Result>
  </Action>
  <Action>
    <Result>Passed</Result>
  </Action>
</Analysis>

我当前拥有的代码将在测试下发现失败，但它只能完成一次。但是，现在它在每个评论下都可以做到，而不是每个评论中都有"测试"。

<xsl:key name="actions" match="Action" use="generate-id(preceding-sibling::comment[1])" />
<xsl:template match="/Analysis">
    <table>
        <xsl:for-each select="comment">
            <tr>
                <td>
                    <xsl:if test="starts-with(text(),'Test')">
                        <xsl:value-of select="."/>
                    </xsl:if>
                </td>
            </tr>   
            <xsl:if test="key('actions', generate-id())[Result='Failed']">
                <tr>
                    <td>Failed</td>
                </tr>
            </xsl:if>
        </xsl:for-each>
    </table>
</xsl:template>

有没有办法使"先前的sibling ::评论" [1]仅适用于以"测试"或包含"测试"开头的注释？有不同数量的非重要注释散布在重要信息中。就像上面的示例一样，我想看到一个像

的输出

Test 1
Failed
Test 2
Failed
Test 3
Test 4
Failed

但是，我目前有代码

Test 1  
Failed 
Test 2 
Failed 
Failed 
Failed 
Test 3 
Test 4 
Failed 
Failed 

任何帮助将不胜感激。

您应该能够将谓词直接添加到xsl:key ...

<xsl:key 
  name="actions" 
  match="Action" 
  use="generate-id(preceding-sibling::comment[starts-with(normalize-space(),'Test')][1])" 
/>

我还将删除xsl:if并将测试放在xsl:for-each上。这样，您就不会得到空白的行以忽略的评论。

完整示例...

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:output indent="yes"/>
  <xsl:strip-space elements="*"/>
  <xsl:key 
    name="actions" 
    match="Action" 
    use="generate-id(preceding-sibling::comment[starts-with(normalize-space(),'Test')][1])" 
  />
  <xsl:template match="/Analysis">
    <table>
      <xsl:for-each select="comment[starts-with(normalize-space(),'Test')]">
        <tr>
          <td>
            <xsl:value-of select="."/>
          </td>
        </tr>
        <xsl:if test="key('actions', generate-id())[Result='Failed']">
          <tr>
            <td>Failed</td>
          </tr>
        </xsl:if>
      </xsl:for-each>
    </table>
  </xsl:template>
</xsl:stylesheet>
