如何将每个父元素复制到子元素中？

Question

我有以下XML:

 <?xml version="1.0" encoding="UTF-8"?>
    <LaborTaskInterface>
          <LaborTask thing100="a" thing2="c" thing3="d" thing4="e" thing500="f" 
          thing6="g" thing7="h" thing8="i" thing9="j">
                <ltOverride unit_id="1" value="1" thing2="k" thing3="c" thing4="d" thing10="o" thing500="z"/>
                <ltOverride unit_id="2" value="1" thing2="l" thing3="c" thing4="d" thing11="p" thing500="z"/>
                <ltOverride unit_id="3" value="1" thing2="m" thing3="c" thing4="d" thing12="q" thing500="z"/>
                <ltOverride unit_id="4" value="1" thing2="n" thing3="c" thing4="d" thing13="r" thing500="z"/>
         </LaborTask>
         <LaborTask thing1="aa" thing2="bb" thing3="dd" thing4="ee" thing5="ff" 
          thing6="gg" thing7="hh" thing8="ii" thing9="jj" thing14="xx">
                <ltOverride unit_id="11" value="11" thing2="kk" thing3="cc" thing4="dd" thing10="oo" thing14="yy"/>
                <ltOverride unit_id="22" value="12" thing2="ll" thing3="cc" thing4="dd" thing11="pp" thing14="yy"/>
                <ltOverride unit_id="33" value="13" thing2="mm" thing3="cc" thing4="dd" thing12="qq" thing14="yy"/>
                <ltOverride unit_id="44" value="14" thing2="nn" thing3="cc" thing4="dd" thing13="rr" thing14="yy"/>
          </LaborTask>
    </LaborTaskInterface>

我正在尝试将 LaborTask 的每个实例 persist/copy 放入每个后续 ItOverride 并删除 LaborTask 节点，以便只有一个 table (ItOverride)。

我正在使用以下 XSLT-1.0（因为 Microsoft Access 要求 XSLT-1.0）：

<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:msxsl="urn:schemas-microsoft-com:xslt"
extension-element-prefixes="msxsl">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>

<xsl:key name="attr-by-name" match="ltOverride/@*" use="name()"/>
<xsl:key name="value" match="ltOverride/@*" use="concat(name(), generate-id(..))"/>

<xsl:template match="/LaborTaskInterface">
    <xsl:variable name="xml" select="/" />
    <!-- base -->
    <xsl:variable name="base-attr" select="LaborTask/@*"/>
    <xsl:variable name="base-elems">
        <xsl:for-each select="$base-attr">
            <xsl:element name="{name()}">
                <xsl:value-of select="." />
            </xsl:element>
        </xsl:for-each>
    </xsl:variable>
    <!-- override -->
    <xsl:variable name="override-columns">
        <xsl:for-each select="LaborTask/ltOverride/@*[generate-id() = generate-id(key('attr-by-name', name())[1])]">
            <col name="{name()}"/>
        </xsl:for-each>      
    </xsl:variable>
    <!-- output -->
    <xsl:copy>
            <xsl:for-each select="LaborTask/ltOverride">
                <xsl:variable name="id" select="generate-id()" />
                <xsl:copy>
                    <xsl:for-each select="$base-elems"/>
                    <xsl:copy-of select="$base-elems"/>
                    <xsl:for-each select="msxsl:node-set($override-columns)/col">
                        <xsl:variable name="name" select="@name" />
                        <xsl:variable name="dup">
                            <xsl:if test="$base-attr[name() = $name]">.2</xsl:if>
                        </xsl:variable>
                        <xsl:element name="{@name}{$dup}">
                            <!-- switch context back to input document in order to use key -->
                            <xsl:for-each select="$xml">
                                <xsl:value-of select="key('value', concat($name, $id))" />
                            </xsl:for-each>
                        </xsl:element>
                    </xsl:for-each>
                </xsl:copy>
            </xsl:for-each>
    </xsl:copy>
</xsl:template>

</xsl:stylesheet>

这是我得到的不想要的输出（我试图循环 $base-elem）：

  </ltOverride>
</LaborTaskInterface>

您可以在上面的输出中看到第一个 LaborTask 实例（其中 thing1="a"）被引入到 8 个 ItOverride 中。

这是期望的输出（请注意第一个 LaborTask 实例如何被带入前 4 个 ItOverride，第二个 LaborTask 实例被带入接下来的 4 个 ItOverride 实例）：
