Issue in moving nodes under new node

Question

I am facing an issue rearranging the nodes in given output structure. Company1, Company2, Company 3 is static. These won't change. So I need three of them in SCompany List.

Company4, and Company5 is dynamic in the sense that either one of these or both of these can be present in NCompany List.

I need nodes with text A1, B2, C3 to be formed under SCompany. If A1 is repeated under any node except <Given> <GivenId>, I don't need those.

Maybe I have to use mode?

Answer 1

This is the basic idea. You'll need to adjust it to satisfy your undocumented requirements.

<xsl:template match="root">
  <xsl:copy>
    <xsl:element name="Scompany">
      <!-- Select the Given nodes that should be in Scompany. Ensure only one Given per GivenId is selected. -->
      <xsl:apply-templates select="Given[GivenId = 'A1'][1]|Given[GivenId = 'B2'][1]|Given[GivenId = 'C3'][1]"/>
    </xsl:element>
    <xsl:element name="Ncompany">
      <!-- Select the given nodes that should be in Ncompany. Ensure only one Given per GivenId is selected.-->
      <xsl:apply-templates select="Given[GivenId = 'F4'][1]|Given[GivenId = 'G5'][1]"/>
    </xsl:element>
  </xsl:copy>
</xsl:template>

<xsl:template match="Given">
  <xsl:element name="{GivenId}">
    <xsl:apply-templates select="node()"/>
  </xsl:element>
</xsl:template>

<xsl:template match="GivenId">
  <xsl:copy>
  </xsl:copy>
</xsl:template>

<xsl:template match="List">
  <xsl:choose>
    <xsl:when test="@id='Same'">
      <xsl:element name="Same">
      </xsl:element>
    </xsl:when>    
    <xsl:when test="@id='Different'">
      <xsl:element name="Different">
      </xsl:element>
    </xsl:when>    
  </xsl:choose>
</xsl:template>

<xsl:template match="Change"/>
