嵌套節點的xslt鍵

Question

我有一個存儲比賽，球隊和球員的xml文件，如下所示。我刪除了與問題無關的其他元素。

基本上我想建立一個表中的每個聯盟（競爭），顯示一個類似的目標數據和助攻相關的每個球員。我正在嘗試使用鍵將這些鏈接在一起。

我一直在掙扎的正確鏈接得分和聯賽。目前它會打印數據，但無論打印哪個聯賽，它都會顯示相同的目標和助攻分數。

• 我試圖扭轉的關鍵類似如下 <xsl:key name="scoreByLeague" match="score" use="@leagueID"/>
• 我已經包裹了進球/助攻value-of select聲明中另一個for-each
• 我曾試圖改變for-each節點的環境

我的猜測是，這個問題是在這條線 <xsl:value-of select="scores/score[key('leagueScore', @leagueID)]/goals"/> ，因爲它似乎是PR除了沒有顯示每個聯盟的獨特價值之外。即第一聯賽的印刷正確，但其餘的聯賽表格只是第一聯的副本。

Answer 1

如果我理解這個正確的，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>
