【问题描述】：

你能帮帮我吗？

如果“PackingslipId”-“LineItem”-“Lines”有不同，我不喜欢在“HeaderInformation”上有“PackingslipId”和“DeliveryDate”。

如果“LineItem”-“Lines”中的“PackingslipId”始终与“HeaderInformation”中的“PackingslipId”相同，则输出“PackingslipId”和“DeliveryDate”正常。

请注意：（如果重要，我不知道；也可以是，只有一篇文章（“LineItem”-“Lines” - 带有“OrderLineNum”1） - 在这种情况下，“PackingslipId”与“Lines”和“HeaderInformation”相同，因此“PackingslipId”和“DeliveryDate”也应该在“HeaderInformation”和“LineItem”上

  <xsl:strip-space elements="*" />
  <xsl:key name="header_text" match="HeaderText" use="Text"/>
  <xsl:key name="line_text" match="LineText" use="concat(../OrderLineNum, '|', Text)"/>

  <xsl:template match="@* | node()">

      <xsl:apply-templates select="@* | node()"/>
    </xsl:copy>
  </xsl:template>

  <!-- no duplilcate on HeaderText and LineText -->
  <xsl:template match="HeaderText[generate-id() != generate-id(key('header_text', Text)[1])]" />
  <xsl:template match="LineText[generate-id() != generate-id(key('line_text', concat(../OrderLineNum, '|', Text))[1])]" />
  
  <!-- delete PackingslipId on HeaderInformation, if different at Line -->
  <xsl:template match="/salesinvoices/lineItem">
    <xsl:choose>
      <xsl:when test="
      count(lines[not(PackingslipId = preceding-sibling::lines/PackingslipId)]) = 1">

        <xsl:copy-of select="//HeaderInformation/PackingslipId"/>
        <xsl:copy-of select="//HeaderInformation/DeliveryDate"/>
   
        </xsl:when>
          <xsl:otherwise>            
          </xsl:otherwise>
        </xsl:choose>
  </xsl:template>

<!-- delete empty nodes -->
 <xsl:template match="node()|@*">
     <xsl:copy>
       <xsl:apply-templates select="node()|@*"/>
     </xsl:copy>
 </xsl:template>

 <xsl:template match="*[not(@*|*|comment()|processing-instruction()) and normalize-space()='']"/>
 
</xsl:stylesheet>

正确的输出应该是：（HeaderInformation 上没有 PackingslipId 和 DeliveryDate，因为 LineItem - PackingslipId 有不同）

    【解决方案1】：

    我认为您只需将这两个模板添加到您的 XSLT

    <xsl:template match="HeaderInformation[PackingslipId != LineItem/Lines/PackingslipId]/PackingslipId" />
<xsl:template match="HeaderInformation[PackingslipId != LineItem/Lines/PackingslipId]/DeliveryDate" />

    或者，如果您想将这两者合二为一，只需添加此模板

    <xsl:template match="HeaderInformation[PackingslipId != LineItem/Lines/PackingslipId]/*[self::PackingslipId or self::DeliveryDate]" />
