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？

Answer 1

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>

Answer 2

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>

每个不同的值循环
