嵌套节点的xslt键

Question

我有一个存储比赛，球队和球员的xml文件，如下所示。我删除了与问题无关的其他元素。

基本上我想建立一个表中的每个联盟（竞争），显示一个类似的目标数据和助攻相关的每个球员。我正在尝试使用键将这些链接在一起。

我一直在挣扎的正确链接得分和联赛。目前它会打印数据，但无论打印哪个联赛，它都会显示相同的目标和助攻分数。

• 我试图扭转的关键类似如下 <xsl:key name="scoreByLeague" match="score" use="@leagueID"/>
• 我已经包裹了进球/助攻value-of select声明中另一个for-each
• 我曾试图改变for-each节点的环境

我的猜测是，这个问题是在这条线 <xsl:value-of select="scores/score[key('leagueScore', @leagueID)]/goals"/> ，因为它似乎是PR除了没有显示每个联盟的独特价值之外。即第一联赛的印刷正确，但其余的联赛表格只是第一联的副本。

Answer 1

如果我理解这个正确的，你想做的事：

<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> 
<xsl:output method="html" encoding="UTF-8"/> 

<xsl:key name="score-by-league" match="score" use="@leagueID"/> 
<xsl:key name="team" match="team" use="@teamCode"/> 

<xsl:template match="/football"> 
    <xsl:for-each select="leagues/league"> 
     <b>Competition: </b> 
     <xsl:value-of select="leagueName"/> 
     <br /> 
     <table> 
      <tr> 
       <th>First Name</th> 
       <th>Surname</th> 
       <th>Team</th> 
       <th>Goals</th> 
       <th>Assists</th> 
      </tr> 
      <xsl:for-each select="key('score-by-league', @leagueCode)"> 
      <tr> 
       <td> 
        <xsl:value-of select="ancestor::player/playerFirstName"/> 
       </td> 
       <td> 
        <xsl:value-of select="ancestor::player/playerSurname"/> 
       </td> 
       <td> 
        <xsl:value-of select="key('team', ancestor::player/@teamID)/teamName"/> 
       </td> 
       <td> 
        <xsl:value-of select="goals"/> 
       </td> 
       <td> 
        <xsl:value-of select="assists"/> 
       </td> 
      </tr> 
      </xsl:for-each> 
     </table> 
     <br /> 
    </xsl:for-each> 
</xsl:template> 

</xsl:stylesheet>
