Hi i am a little stuck with this problem my xml is as
<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>
i would like to be able to output as
<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...
im sure that i need to use some sort of Muenchian grouping but im having difficulty getting my head around it for my particular usage.
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="html" indent="yes"/>
<xsl:key name="sortByDisk" match="track" use="@disksequence"/>
<xsl:template match="/*">
<body>
<xsl:apply-templates select="tracks/track[
count(. | key('sortByDisk', @disksequence)[1]) = 1
]"/>
</body>
</xsl:template>
<xsl:template match="track">
<div>
<span>
<xsl:value-of select="../../title"/>
<xsl:text> disc</xsl:text>
<xsl:value-of select="@disksequence"/>
</span>
<xsl:apply-templates select="key('sortByDisk', @disksequence)"
mode="inner"/>
</div>
</xsl:template>
<xsl:template match="track" mode="inner">
<p><xsl:value-of select="."/></p>
</xsl:template>
</xsl:stylesheet>
Output (using your sample):
<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>
