RE: [xsl] favor certain elements

[Emmanuel Bégué <eb@xxxxxxxxxx>]

Hello,

Have you tried grouping? Using this template:

<xsl:template match="/root">
  <root>
    <elementx>
      <xsl:for-each-group select="*/*" group-by="local-name()">
        <xsl:choose>
          <xsl:when test="local-name()='a'">
            <xsl:copy-of select="current-group()[1]"/>
            </xsl:when>
          <xsl:when test="local-name()='b'">
            <xsl:copy-of select="current-group()[last()]"/>
            </xsl:when>
          <xsl:otherwise>
            <!-- some default rule should go here -->
            <xsl:copy-of select="current-group()[1]"/>
            </xsl:otherwise>
          </xsl:choose>
        </xsl:for-each-group>
      </elementx>
    </root>
  </xsl:template>

this source:

<root>
   <element1>
       <a>first a (from 1)</a>
       <b>first b (from 1)</b>
   </element1>
   <element2>
       <a>second a (from 2)</a>
       <b>second b (from 2)</b>
       <c>first c (from 2)</c>
   </element2>
   <element3>
       <a>third a (from 3)</a>
       <b>third b (from 3)</b>
       <c>second c (from 3)</c>
   </element3>
</root>

gives this result:

<root>
   <elementx>
      <a>first a (from 1)</a>
      <b>third b (from 3)</b>
      <c>first c (from 2)</c>
   </elementx>
</root>

EB
