Muenchian Grouping - 通过不出现在 xml 结果中进行分组

Question

我有以下 CSV 文件，因此 XSD 看起来像这样：

123456|123456777|Green|Grün
123456|123456888|Red|Rot
987654|987654333|Yellow|Gelb

In XML format it looks like this:
<Product xmlns="http://F.FlatFileSchema1">
    <Products xmlns="">
        <product>123456</product>
        <sku>123456777</sku>
        <parentcolour_EN>Green</parentcolour_EN>
        <parentcolour_DE>Grün</parentcolour_DE>
    </Products>
    <Products xmlns="">
        <product>123456</product>
        <sku>123456888</sku>
        <parentcolour_EN>Red</parentcolour_EN>
        <parentcolour_DE>Rot</parentcolour_DE>
    </Products>
    <Products xmlns="">
        <product>987654</product>
        <sku>987654333</sku>
        <parentcolour_EN>Yellow</parentcolour_EN>
        <parentcolour_DE>Gelb</parentcolour_DE>
    </Products>
</Product>

目的是将其转换为具有以下格式的xml：

<?xml version="1.0" encoding="utf-8"?>
<enfinity xsi:schemaLocation="http://www.intershop.com/xml/ns/enfinity/7.0/xcs/impex catalog.xsd http://www.intershop.com/xml/ns/enfinity/6.5/core/impex-dt dt.xsd" major="6" minor="1" family="enfinity" branch="enterprise" build="build" xmlns="http://www.intershop.com/xml/ns/enfinity/7.0/xcs/impex" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:dt="http://www.intershop.com/xml/ns/enfinity/6.5/core/impex-dt">
  <offer sku="123456777">
    <custom-attributes>
      <custom-attribute name="parentcolour" dt:dt="string" xml:lang="en-US">Green</custom-attribute>
      <custom-attribute name="parentcolour" dt:dt="string" xml:lang="de-DE">Grün</custom-attribute>
    </custom-attributes>
  </offer>
  <offer sku="123456888">
    <custom-attributes>
      <custom-attribute name="parentcolour" dt:dt="string" xml:lang="en-US">Red</custom-attribute>
      <custom-attribute name="parentcolour" dt:dt="string" xml:lang="de-DE">Rot</custom-attribute>
    </custom-attributes>
  </offer>
  <offer sku="123456">
    <variations>
      <mastered-products>
        <mastered-product sku="123456777" domain="MasterRepository"/>
        <mastered-product sku="123456888" domain="MasterRepository"/>
      </mastered-products>
    </variations>
  </offer>
  <offer sku="987654333">
    <custom-attributes>
      <custom-attribute name="parentcolour" dt:dt="string" xml:lang="en-US">Yellow</custom-attribute>
      <custom-attribute name="parentcolour" dt:dt="string" xml:lang="de-DE">Gelb</custom-attribute>
    </custom-attributes>
  </offer>
  <offer sku="987654">
    <variations>
      <mastered-products>
        <mastered-product sku="987654333" domain="MasterRepository"/>
      </mastered-products>
    </variations>
  </offer>
</enfinity>

正如您所见，所有 3 个 sku 都出现在 XML 中，但还需要在 sku 末尾出现一个附加产品，即 123456 出现在 123456777 和 123456888 之后，987654 出现在 987654333 之后。到目前为止我无法显示应用 Muenchian 分组后产品级别的变化块。我当前的 XSL 如下所示：

                        <mastered-products>
                            <!-- for each member of current group -->
                            <xsl:for-each select="key('groupbyproduct', product)">

Answer 1

密钥没有意义，我认为你想要<xsl:key name="groupbyproduct" match="Products" use="product"/>，而不是你想要的第二个for-each

        <!-- create a group for each unique product -->
        <xsl:for-each select="Products[count(. | key('groupbyproduct', product)[1]) = 1]">
            <offer sku="{product}">
                <variations>
                    <mastered-products>
                        <!-- for each member of current group -->
                        <xsl:for-each select="key('groupbyproduct', product)">
                            <mastered-product sku="{sku}" domain="MasterRepository"/>
                        </xsl:for-each>
                    </mastered-products>
                </variations>
            </offer>
        </xsl:for-each>

至于您的评论和您想要的完整结果，看起来好像首先分组然后在内部输出不同的数据应该给出您想要的顺序：

    <xsl:for-each select="Products[count(. | key('groupbyproduct', product)[1]) = 1]">
      <xsl:for-each select="key('groupbyproduct', product)">
            <offer sku="{sku}">
                <custom-attributes>
                    <custom-attribute name="parentcolour" dt:dt="string" xml:lang="en-US">
                        <xsl:value-of select="parentcolour_EN/text()"/>
                    </custom-attribute>
                    <custom-attribute name="parentcolour" dt:dt="string" xml:lang="de-DE">
                        <xsl:value-of select="parentcolour_DE/text()"/>
                    </custom-attribute>
                </custom-attributes>
            </offer>
        </xsl:for-each>
        <offer sku="{product}">
            <variations>
                <mastered-products>
                    <!-- for each member of current group -->
                    <xsl:for-each select="key('groupbyproduct', product)">
                        <mastered-product sku="{sku}" domain="MasterRepository"/>
                    </xsl:for-each>
                </mastered-products>
            </variations>
        </offer>
    </xsl:for-each>
