我正在尝试获得所有不同的冲刺，并且在这些不同的冲刺内，我希望看到属于冲刺的所有不同项目。为了这样做，这是我的xsl

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema" version="2.0">

<xsl:variable name="sprints" select="sprints/sprint" />
<xsl:variable name="items" select="sprints/sprint/items/item" />
<xsl:template match="/">

sprint是截然不同的，但是所有的项目都出现在所有冲刺中，我希望与正确的sprint相匹配。我怎么能这样做？
答案 0 :(得分：3)
使用xsl：for-each-group而不是distinct-values更容易实现，因为distinct-values只为您提供不同的日期值，而for-each-groups为您提供了每个不同的sprint组日期值。
所以你想要这样的东西：
<xsl:for-each-group select="/sprints/sprint" group-by="enddate">
<sprint>
<enddate><xsl:value-of select="current-grouping-key()"/></enddate>
<items>
<xsl:for-each-group select="current-group()/item" group-by="biid">
...
</xsl:for-each-group>
</items>
</sprint>
</xsl:for-each-group>
答案 1 :(得分：1)
这是一个解决方案。
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema" version="2.0">
<xsl:output method="xml" indent="yes" />
<xsl:variable name="sprints" select="/sprints/sprint" />
<xsl:template match="/">
<root>
<sprints>
<xsl:for-each select="distinct-values(sprints/sprint/testenddate)">
<xsl:variable name="date" select="."/>
<sprint>
<enddate><xsl:value-of select="." /></enddate>
<items>
<xsl:for-each select="distinct-values($sprints[testenddate/text()=$date]/items/item/biid)">
<item>
<xsl:value-of select="." />
</item>
</xsl:for-each>
</items>
</sprint>
</xsl:for-each>
</sprints>
</root>
</xsl:template>
</xsl:stylesheet>
这是使用XSLT 2.0的分组功能编写的相同解决方案，不需要变量：
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema" version="2.0">
<xsl:output method="xml" indent="yes" />
<xsl:template match="/">
<root>
<sprints>
<xsl:for-each-group select="/sprints/sprint" group-by="testenddate">
<sprint>
<enddate><xsl:value-of select="current-grouping-key()"/></enddate>
<items>
<xsl:for-each select="distinct-values(current-group()/items/item/biid)">
<item>
<xsl:value-of select="." />
</item>
</xsl:for-each>
</items>
</sprint>
</xsl:for-each-group>
</sprints>
</root>
</xsl:template>
</xsl:stylesheet>
