Question

这是输入文件。

<XML>
<Box Price="541" Key="1">
<Leg Key="56T58T" Group="0"></Leg>
<Leg Key="177T179T" Group="1"></Leg>
</Box>
<Box Price="541" Key="2">
<Leg Key="128T130T" Group="0"></Leg>
<Leg Key="196T198T" Group="1"></Leg>
</Box>
<Box Price="541" Key="3">
<Leg Key="56T58T" Group="0"></Leg>
<Leg Key="196T198T" Group="1"></Leg>
</Box>
<Box Price="541" Key="4">
<Leg Key="128T130T" Group="0"></Leg>
<Leg Key="177T179T" Group="1"></Leg>
</Box>
<Box Price="541" Key="5">
<Leg Key="243T246T" Group="0"></Leg>
<Leg Key="60T63T" Group="1"></Leg>
</Box>
<Box Price="541" Key="6">
<Leg Key="243T246T" Group="0"></Leg>
<Leg Key="133T136T" Group="1"></Leg>
</Box>
<Box Price="700" Key="7">
<Leg Key="243T" Group="0"></Leg>
<Leg Key="133T136T" Group="1"></Leg>
</Box>
</XML>

输出结果为：

<Box Price="541">
<Leg Key="56T58T" Group="0"></Leg>
<Leg Key="128T130T" Group="0"></Leg>
<Leg Key="177T179T" Group="1"></Leg>
<Leg Key="196T198T" Group="1"></Leg>
</Box>
<Box Price="541">
<Leg Key="243T246T" Group="0"></Leg>
<Leg Key="133T136T" Group="1"></Leg>
<Leg Key="60T63T" Group="1"></Leg>
</Box>
<Box Price="700">
<Leg Key="243T" Group="0"></Leg>
<Leg Key="133T136T" Group="1"></Leg>
</Box>

分组规则

价格

腿组= 0，gropup = 1是对。当leg Group = 0时，我们可以对leg进行分组，其中Key = in Group = 1。例如，组中的腿= 0具有键= 56T58T并且组中的两个键（177T179T和196T198T）= 1。相同的两个键（177T179T和196T198T）具有Leg in Group = 0 Key = 128T130T。所以我们可以将它分组

<Box Price="541">
<Leg Key="56T58T" Group="0"></Leg>
<Leg Key="128T130T" Group="0"></Leg>
<Leg Key="177T179T" Group="1"></Leg>
<Leg Key="196T198T" Group="1"></Leg>
</Box>

我正在使用XSLT 1.0。任何帮助都会非常感激。

我有xsl，但它只按价格分组

<xsl:output method="xml" indent="yes" />

<xsl:key name="price" match="Box" use="@Price" />


<xsl:template match="XML">
        <xsl:apply-templates select="Box[generate-id(.)=generate-id(key('price',@Price)[1])]"/>
</xsl:template>


<xsl:template match="Box">
    <Group Price="{@Price}">
        <xsl:for-each select="key('price', @Price)"> 
      <xsl:for-each select="Leg">  
            <Leg Key="{@Key}" Group="{@Group}"></Leg>
         </xsl:for-each>
        </xsl:for-each>
    </Group>
</xsl:template>

和输出：

<?xml version="1.0"?>
<Group Price="541">
 <Leg Key="56T58T" Group="0"/>
 <Leg Key="177T179T" Group="1"/>
 <Leg Key="128T130T" Group="0"/>
 <Leg Key="196T198T" Group="1"/>
 <Leg Key="56T58T" Group="0"/>
 <Leg Key="196T198T" Group="1"/>
 <Leg Key="128T130T" Group="0"/>
 <Leg Key="177T179T" Group="1"/>
 <Leg Key="243T246T" Group="0"/>
 <Leg Key="60T63T" Group="1"/>
 <Leg Key="243T246T" Group="0"/>
 <Leg Key="133T136T" Group="1"/>
</Group><Group Price="700">
  <Leg Key="243T" Group="0"/>
  <Leg Key="133T136T" Group="1"/>
</Group>

任何帮助都会非常感激。

逐步分组。

按相同价格分组并且Leg Group的相同键= 0

<Group Price="541"> <Leg Key="56T58T" Group="0"></Leg> <Leg Key="177T179T" Group="1"></Leg> <Leg Key="56T58T" Group="0"></Leg> <Leg Key="196T198T" Group="1"></Leg> </Group> <Group Price="541"> <Leg Key="128T130T" Group="0"></Leg> <Leg Key="196T198T" Group="1"></Leg> <Leg Key="128T130T" Group="0"></Leg> <Leg Key="177T179T" Group="1"></Leg> </Group> <Group Price="541"> <Leg Key="243T246T" Group="0"></Leg> <Leg Key="60T63T" Group="1"></Leg> <Leg Key="243T246T" Group="0"></Leg> <Leg Key="133T136T" Group="1"></Leg> </Group> <Group Price="700"> <Leg Key="243T" Group="0"></Leg> <Leg Key="133T136T" Group="1"></Leg> </Group>
在每个组中删除重复的Legs（相同的Key）

<Group Price="541" > <Leg Key="56T58T" Group="0"></Leg> <Leg Key="177T179T" Group="1"></Leg> <Leg Key="196T198T" Group="1"></Leg> </Group> <Group Price="541"> <Leg Key="128T130T" Group="0"></Leg> <Leg Key="196T198T" Group="1"></Leg> <Leg Key="177T179T" Group="1"></Leg> </Group> <Group Price="541"> <Leg Key="243T246T" Group="0"></Leg> <Leg Key="60T63T" Group="1"></Leg> <Leg Key="133T136T" Group="1"></Leg> </Group> <Group Price="700"> <Leg Key="243T" Group="0"></Leg> <Leg Key="133T136T" Group="1"></Leg> </Group>
将Leg Group的相同价格和相同的密钥分组= 1（首先是第二组具有相同的Legs组= 1，所以我们可以Gruop）

<Group Price="541"> <Leg Key="56T58T" Group="0"></Leg> <Leg Key="177T179T" Group="1"></Leg> <Leg Key="196T198T" Group="1"></Leg> <Leg Key="128T130T" Group="0"></Leg> <Leg Key="196T198T" Group="1"></Leg> <Leg Key="177T179T" Group="1"></Leg> </Group> <Group Price="541"> <Leg Key="243T246T" Group="0"></Leg> <Leg Key="60T63T" Group="1"></Leg> <Leg Key="133T136T" Group="1"></Leg> </Group> <Group Price="700"> <Leg Key="243T" Group="0"></Leg> <Leg Key="133T136T" Group="1"></Leg> </Group>
在每个组中删除重复的Legs（相同的Key）

<Group Price="541"> <Leg Key="56T58T" Group="0"></Leg> <Leg Key="128T130T" Group="0"></Leg> <Leg Key="177T179T" Group="1"></Leg> <Leg Key="196T198T" Group="1"></Leg> </Group> <Group Price="541"> <Leg Key="243T246T" Group="0"></Leg> <Leg Key="60T63T" Group="1"></Leg> <Leg Key="133T136T" Group="1"></Leg> </Group> <Group Price="700"> <Leg Key="243T" Group="0"></Leg> <Leg Key="133T136T" Group="1"></Leg> </Group>

最终是它的输出。

Answer 1

为了推动这一进展，我发布了这个试验性的样式表，可能与你想要的一样接近：

XSLT 1.0

<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>

<xsl:key name="box-by-price" match="Box" use="@Price" />
<xsl:key name="box-by-legs" match="Box" use="Leg/@Key" />
<xsl:key name="leg-by-key" match="Leg" use="@Key" />

<xsl:template match="XML">
    <root>
        <!-- (1) group by price -->
        <xsl:for-each select="Box[generate-id()=generate-id(key('box-by-price',@Price)[1])]">
            <!-- (2) within each price group, combine boxes that share a common leg (regardless of group) -->
            <xsl:for-each select="key('box-by-price',@Price)[generate-id()=generate-id(key('box-by-legs',Leg/@Key)[1])]">
                <Group Price="{@Price}">
                    <!-- (3) in each group, list the unique legs of all the boxes in the group -->
                        <xsl:copy-of select="key('box-by-legs',Leg/@Key)/Leg[generate-id()=generate-id(key('leg-by-key',@Key)[1])]"/>
                </Group>
            </xsl:for-each>
        </xsl:for-each>
    </root>
</xsl:template>

</xsl:stylesheet>

当此功能应用于输入：

时

<?xml version="1.0" encoding="UTF-8"?>
<XML>
   <Box Price="541" Key="1">
      <Leg Key="56T58T" Group="0"/>
      <Leg Key="177T179T" Group="1"/>
   </Box>
   <Box Price="541" Key="2">
      <Leg Key="128T130T" Group="0"/>
      <Leg Key="196T198T" Group="1"/>
   </Box>
   <Box Price="541" Key="3">
      <Leg Key="56T58T" Group="0"/>
      <Leg Key="196T198T" Group="1"/>
   </Box>
   <Box Price="541" Key="4">
      <Leg Key="128T130T" Group="0"/>
      <Leg Key="177T179T" Group="1"/>
   </Box>
   <Box Price="541" Key="5">
      <Leg Key="243T246T" Group="0"/>
      <Leg Key="60T63T" Group="1"/>
   </Box>
   <Box Price="541" Key="6">
      <Leg Key="243T246T" Group="0"/>
      <Leg Key="133T136T" Group="1"/>
   </Box>
   <Box Price="700" Key="7">
      <Leg Key="243T" Group="0"/>
      <Leg Key="133T136T" Group="1"/>
   </Box>
</XML>

结果是：

<?xml version="1.0" encoding="UTF-8"?>
<root>
   <Group Price="541">
      <Leg Key="56T58T" Group="0"/>
      <Leg Key="177T179T" Group="1"/>
   </Group>
   <Group Price="541">
      <Leg Key="128T130T" Group="0"/>
      <Leg Key="196T198T" Group="1"/>
   </Group>
   <Group Price="541">
      <Leg Key="243T246T" Group="0"/>
      <Leg Key="60T63T" Group="1"/>
      <Leg Key="133T136T" Group="1"/>
   </Group>
</root>

Answer 2

有趣的作业......

我认为答案在Muenchian Grouping中并不像递归那样多。您可以按照第一组的引用路径并注册所遵循的路径的键在对该特定路径的所有Leg元素进行分组之后，您可以继续前进到尚未访问的下一个Box＆＃34;创建下一组

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    version="1.0">

    <xsl:output indent="yes"/>

    <xsl:template match="XML">

            </xsl:call-template>
        </XML>
    </xsl:template>

    <xsl:template name="process-group-node">

                <xsl:with-param name="current-leg" select="$box/Leg[1]"/>
            </xsl:call-template>
        </xsl:variable>
        <Box Price="{$box/@Price}">

            </xsl:call-template>
        </xsl:if>
    </xsl:template>

    <xsl:template name="search-path">

        <xsl:param name="current-leg"/>
        <xsl:choose>

            </xsl:when>
            <xsl:otherwise>
                <xsl:variable name="this-id" select="generate-id($current-leg)"/>
                <xsl:variable name="this-key" select="concat($current-leg/parent::Box/@Price, '-', $current-leg/@Key, '-', $current-leg/@Group)"/>
                <xsl:variable name="next-equivalent-leg" select="key('link', $this-key)[not(generate-id() = $this-id)]"/>
                <xsl:variable name="next-equivalent-id" select="generate-id($next-equivalent-leg)"/>
                <xsl:variable name="next-leg" select="$next-equivalent-leg/parent::Box/Leg[not(generate-id() = $next-equivalent-id)]"/>
                <xsl:call-template name="search-path">
