XSL转换 - 主细节

Question

我需要将XML从一个结构转换到另一个结构。我不知道如何做到这一点。第一个xml看起来不像主细节，但最终的结果需要看起来像肥大的细节。

<?xml version = '1.0' encoding = 'UTF-8'?> 
    <Root-Element xmlns="http://example.com/ReadProductB"> 
     <RECORD1> 
      <C2>QGGG9.A1-1</C2> 
     </RECORD1> 
     <RECORD2> 
      <C2>xflowcode</C2> 
      <C3>FL1</C3> 
     </RECORD2> 
     <RECORD2> 
      <C2>xtilo</C2> 
      <C3>1234</C3> 
     </RECORD2> 
     <RECORD2> 
      <C2>xwat</C2> 
      <C3>75</C3> 
     </RECORD2> 
     <RECORD1> 
      <C2>QGGG9.A1-2</C2> 
     </RECORD1> 
     <RECORD2> 
      <C2>xflowcode</C2> 
      <C3>FL1</C3> 
     </RECORD2> 
     <RECORD2> 
      <C2>xtilo</C2> 
      <C3>1234</C3> 
     </RECORD2> 
     <RECORD2> 
      <C2>xwat</C2> 
      <C3>75</C3> 
     </RECORD2> 
    </Root-Element> 

这是我想要的结果。

<?xml version = '1.0' encoding = 'UTF-8'?> 
    <ns0:ProductCollection xmlns:ns0="http://example.com/ReadProductBB" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> 
     <ns0:RECORD1> 
      <ns0:C2>QGGG9.A1-1</ns0:C2> 
      <ns0:RECORD2Collection> 
      <ns0:RECORD2> 
       <ns0:C2>xflowcode</ns0:C2> 
       <ns0:C3>FL1</ns0:C3> 
      </ns0:RECORD2> 
      <ns0:RECORD2> 
       <ns0:C2>xtilo</ns0:C2> 
       <ns0:C3>1234</ns0:C3> 
      </ns0:RECORD2> 
      <ns0:RECORD2> 
       <ns0:C2>xwat</ns0:C2> 
       <ns0:C3>75</ns0:C3> 
      </ns0:RECORD2> 
      </ns0:RECORD2Collection> 
     </ns0:RECORD1> 
     <ns0:RECORD1> 
      <ns0:C2>QGGG9.A1-2</ns0:C2> 
      <ns0:RECORD2Collection> 
      <ns0:RECORD2> 
       <ns0:C2>xflowcode</ns0:C2> 
       <ns0:C3>FL1</ns0:C3> 
      </ns0:RECORD2> 
      <ns0:RECORD2> 
       <ns0:C2>xtilo</ns0:C2> 
       <ns0:C3>1234</ns0:C3> 
      </ns0:RECORD2> 
      <ns0:RECORD2> 
       <ns0:C2>xwat</ns0:C2> 
       <ns0:C3>75</ns0:C3> 
      </ns0:RECORD2> 
      </ns0:RECORD2Collection> 
     </ns0:RECORD1> 
    </ns0:ProductCollection> 

请帮忙。由于

Answer 2

这个样式表使用通用的模板移动原始元素的名称相同的名称空间ns0。

的RECORD2元件配对与他们通过使用generate-id识别当前RECORD1对应RECORD1元件，然后处理所有以下RECORD2元件，其第一RECORD1元件之前具有相同的ID。

<?xml version="1.0" encoding="UTF-8"?> 
<xsl:stylesheet 
    xmlns:src="http://example.com/ReadProductB" 
    xmlns:ns0="http://example.com/ReadProductBB" 
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform" 
    exclude-result-prefixes="src" 
    version="1.0"> 

    <xsl:strip-space elements="*"/> 
    <xsl:output method="xml" indent="yes" encoding="UTF-8"/> 

    <xsl:template match="/src:Root-Element"> 
     <ns0:ProductCollection> 
      <xsl:apply-templates select="src:RECORD1"/> 
     </ns0:ProductCollection> 
    </xsl:template> 

    <xsl:template match="src:RECORD1"> 
     <ns0:RECORD1> 
      <xsl:apply-templates/> 
      <xsl:variable name="record1" select="generate-id()"/> 
      <ns0:RECORD2Collection> 
       <xsl:for-each select="following-sibling::src:RECORD2"> 
        <xsl:if test="generate-id(preceding-sibling::src:RECORD1[1]) = $record1"> 
         <xsl:apply-templates select="."/> 
        </xsl:if> 
       </xsl:for-each> 
      </ns0:RECORD2Collection> 
     </ns0:RECORD1>

    <xsl:template match="*">

输出
