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。我已经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进球和助攻等统计数据。我正在尝试使用键将它们链接在一起。

我一直在努力解决的是将分数和联赛正确关联起来。目前它会打印数据，但无论打印哪个联赛，它都会显示相同的进球和助攻得分。

• 我尝试过如下反转密钥 <xsl:key name="scoreByLeague" match="score" use="@leagueID"/>
• 我已将目标/助攻的 value-of select 声明包装在另一个 for-each 中
• 我已尝试更改 for-each 节点的上下文

我的猜测是问题出在这一行 <xsl:value-of select="scores/score[key('leagueScore', @leagueID)]/goals"/> 因为它似乎正在打印数据，但它没有显示每个联赛的唯一值。即第一个联赛打印正确，但所有剩余的联赛表只是第一个的副本。

如果我理解正确，你想这样做：

<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>
                <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>
