将XML文件平坦化为树状结构分组字段

我是XSL转换的新手，我想将XML A转换为XML B.任何有关在XSLT或xquery中实现这一点的建议。我尝试使用上MSISDN 的for-each-组，但仍无法达到it.Any示例代码以开始与将XML文件平坦化为树状结构分组字段

XML答：

<Output>

</usage>

我的想法是首先对msisdn进行分组，然后遍历int它的领域。下面是我尝试

<xsl:template match="/"> 
    <tns:UsageHistoryResponse> 
     <xsl:for-each select="/Output/response"> 
      <tns:usage> 
       <xsl:for-each-group select="." group-by="ns0:msisdn"> 
        <tns:MSISDN> 
        <xsl:value-of select="current-grouping-key()"/></tns:MSISDN> 
       </xsl:for-each-group> 
      </tns:usage> 
     </xsl:for-each> 
    </tns:UsageHistoryResponse> 
</xsl:template>

这里展示了如何实现两个包装元素的分组和另外一个解决方案：

<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0"> 

    <xsl:output indent="yes"/> 
    <xsl:strip-space elements="*"/> 

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

    <xsl:template match="Output"> 
     <UsageHistoryResponse>   
      <xsl:for-each-group select="response" group-by="msisdn"> 
       <usage> 
       <MSISDN> 
        <xsl:value-of select="current-grouping-key()"/> 
       </MSISDN> 
       <CombinedUsage> 
        <xsl:apply-templates select="current-group()"/> 
       </CombinedUsage> 
       <SharedUsage> 
        <xsl:apply-templates select="current-group()" mode="shared"/> 
       </SharedUsage> 
       </usage> 
      </xsl:for-each-group> 
     </UsageHistoryResponse> 
    </xsl:template> 

    <xsl:template match="response" mode="#default shared"> 
     <usage_info> 
      <xsl:apply-templates mode="#current"/> 
     </usage_info> 
    </xsl:template> 

    <xsl:template match="msisdn" mode="#all"/> 

    <xsl:template match="response/*[starts-with(local-name(), 'shared')]"/> 

    <xsl:template match="response/*[starts-with(local-name(), 'comb')]" mode="shared"/> 

    <xsl:template match="comb_cnt"> 
     <bearer_units> 
      <xsl:apply-templates/> 
     </bearer_units> 
    </xsl:template> 

</xsl:transform>

      <shared_data_cnt>0</shared_data_cnt> 
     </usage_info> 
     </SharedUsage> 
    </usage> 
</UsageHistoryResponse>

这样一些工作留下来重命名元素，可以简单地通过添加模板来实现，然后你也似乎想要添加一些数据，我不知道数据如

<bearer_usage_uom>Seconds</bearer_usage_uom>

应该取自。

对于一个解释：我已经使用for-each-group，你想和作为XSLT进行分组2.0提供的工具，只是我已经使用在正确的上下文（match="Output"）右人口（select="response"）。如果您很难理解这一点，请尝试使用XSLT 2.0分组教程。由于您似乎想要处理组中的每个项目两次，因此我已经使用模式来完成该操作，因此要构建CombinedUsage我已经使用了默认模式，以构建SharedUsaged我已经使用了不同的模式。剩下的就是为输入中的元素编写模板，将其映射到输出中的元素，并确保不希望某些模式的结果中的元素不能通过使用空模板复制。

感谢您的解决方案Martin。我需要XML B中的两个使用标签，因为XML A中有两个不同的msisdn。 –

@NaveenzRock，我已更正'usage'元素的位置，不知何故，我是第一次尝试把它放在'for-each-group'外面，当你需要它的时候。 –

你能给我解释一下吗？我的逻辑走得没那么复杂（至少对我来说）。我想理解这个逻辑并建立最终的xsl。您分享的网站是好的。直接我们可以编辑东西 –
