嗨，我有点卡在这个问题上，我的 xml 是

<album>
     <title>album name</title>    
     <tracks>
           <track tracksequence="1" disksequence="1">track 1 - disc 1</track>
           <track tracksequence="2" disksequence="1">track 2 - disc 1</track>
           <track tracksequence="3" disksequence="1">track 3 - disc 1</track>
           <track tracksequence="1" disksequence="2">track 1 - disc 2</track>
           <track tracksequence="2" disksequence="2">track 2 - disc 2</track>
           <track tracksequence="3" disksequence="2">track 3 - disc 2</track>
           <track tracksequence="4" disksequence="2">track 4 - disc 2</track>
           <track tracksequence="1" disksequence="3">track 1 - disc 3</track>
           <track tracksequence="2" disksequence="3">track 2 - disc 3</track>
     </tracks>
</album>

我希望能够输出为

<div>
<span>album name disc 1</span>
track 1 disc 1
track 2 disc 1
track 3 disc 1
</div>

<div>
<span>album name disc 2</span>
track 1 disc 2
track 2 disc 2
track 3 disc 2
track 4 disc 2 
</div>

ect...

我确定我需要使用某种 Muenchian 分组，但对于我的特定用途，我很难理解它。

</xsl:template>

<xsl:template match="track" mode="inner">

</xsl:stylesheet>

输出（使用您的示例）：

<body>
    <div>
        <span>album name disc1</span>
        <p>track 1 - disc 1</p>
        <p>track 2 - disc 1</p>
        <p>track 3 - disc 1</p>
    </div>
    <div>
        <span>album name disc2</span>
        <p>track 1 - disc 2</p>
        <p>track 2 - disc 2</p>
        <p>track 3 - disc 2</p>
        <p>track 4 - disc 2</p>
    </div>
    <div>
        <span>album name disc3</span>
        <p>track 1 - disc 3</p>
        <p>track 2 - disc 3</p>
    </div>
</body>
