XSLT 1.0 复制并删除节点

问题描述 投票：0回答：1

我必须复制一个节点（Set_Item/ForwarderReferenceNumber）以防倍增，然后删除我们从中获取值的节点“Set_Item”。

要查找相同的 Set_Item（但不同的 ForwarderReferenceNumer），我们必须使用“Set_Item/GTIN”）。 -> 因此，在我的示例中，我们可以看到“LineNum”2 和 7 的“GTIN”相同 (555)，现在我们必须将第 7 行的“Set_Item/ForwarderReferenceNumber”复制到该行的“Set_Item/ForwarderReferenceNumber”下方2 然后用“LineNum”删除“Set_Item”的完整节点 7.

XML 示例：

<OSTRPT>
  <LineInformation>  
    <Set_Item>
      <LineNum>2</LineNum>
      <GTIN>555</GTIN>      
      <Quantity>1.00</Quantity>
      <MeasureUnit>PCE</MeasureUnit>
      <DeliveryDate>2024-03-13</DeliveryDate>
      <Status>24</Status>     
      <ForwarderReferenceNumber>666</ForwarderReferenceNumber>  
      <Date>2</Date>          
    </Set_Item>
    <Set_Item>
      <LineNum>7</LineNum>
      <GTIN>555</GTIN>     
      <Quantity>1.00</Quantity>
      <MeasureUnit>PCE</MeasureUnit>
      <DeliveryDate>2024-03-13</DeliveryDate>
      <Status>24</Status>      
      <ForwarderReferenceNumber>777</ForwarderReferenceNumber> 
      <Date>3</Date>          
    </Set_Item>
  </LineInformation>
</OSTRPT>

这应该是正确的输出：

<OSTRPT>
  <LineInformation>  
    <Set_Item>
      <LineNum>2</LineNum>
      <GTIN>555</GTIN>      
      <Quantity>1.00</Quantity>
      <MeasureUnit>PCE</MeasureUnit>
      <DeliveryDate>2024-03-13</DeliveryDate>
      <Status>24</Status>     
      <ForwarderReferenceNumber>666</ForwarderReferenceNumber>
      <ForwarderReferenceNumber>777</ForwarderReferenceNumber> 
      <Date>2</Date>      
    </Set_Item>
  </LineInformation>
</OSTRPT>

这是我当前的 xslt。 （但这种情况没有解决方案）

使用密钥并处理由该密钥形成的“组”中的所有 ForwarderReferenceNumber：

const xslt = `<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">

<xsl:key name="group" match="Set_Item" use="GTIN"/>

<xsl:template match="Set_Item[not(generate-id() = generate-id(key('group', GTIN)[1]))]"/>

<xsl:template match="ForwarderReferenceNumber">
  <xsl:copy-of select=". | key('group', ../GTIN)/ForwarderReferenceNumber"/>
</xsl:template>

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

</xsl:stylesheet>`;

var domParser = new DOMParser();

var xsltProcessor = new XSLTProcessor();

xsltProcessor.importStylesheet(domParser.parseFromString(xslt, 'application/xml'));

var resultDoc = xsltProcessor.transformToDocument(domParser.parseFromString(document.getElementById('xml').text, 'application/xml'));

console.log(resultDoc);

console.log(new XMLSerializer().serializeToString(resultDoc));
<script id="xml" type="application/xml">
