Question

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

基本上我想为每个联赛（比赛）设置一个表格，以显示与每个球员相关的目标和助攻等统计数据。而我正在尝试使用密钥将这些链接在一起。

我一直在努力的是正确地将分数和联赛联系起来。目前它打印数据，但它显示相同的目标，并协助得分，无论正在打印哪个联赛。

我试过像下面那样反转键 <xsl:key name="scoreByLeague" match="score" use="@leagueID"/>
我已将目标/助理的value-of select语句包含在另一个for-each
我尝试更改for-each节点

我的猜测是问题就在这条线上 <xsl:value-of select="scores/score[key('leagueScore', @leagueID)]/goals"/> 因为它似乎是在打印数据，除了它没有显示每个联盟的唯一值。即第一个联赛打印正确，但所有剩余的联赛表只是第一个联赛的副本。

Answer 1

如果我理解正确，你想做：

<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>
