Re: Re: Re: Re: Unbounded element grouping/concatenati

Dimitre,

One change to your algorithm... the xsl:choose inside the record 
match is not required because the continuation records are copied
when each header record is selected. Slightly simpler and I don't
think I broke anything (gives me the same result for my test
case anyway). Here is the new version:


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

  <xsl:output omit-xml-declaration="yes" indent="yes"/>

  <xsl:variable name="vposArray">
    <xsl:value-of select="'|'"/>
    <xsl:for-each select="/*/record">
      <xsl:if test="@type = 'normal'">
        <xsl:value-of select="concat(position(), '|')"/>
      </xsl:if>
    </xsl:for-each>
  </xsl:variable>

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

  <xsl:template match="records">
    <records>
      <xsl:apply-templates select="record"/>
    </records>
  </xsl:template>

  <xsl:template match="record">
    <xsl:variable name="vPos" select="position()"/>
    <xsl:variable name="vposNext"
      select="substring-before(
                      substring-after($vposArray,
                                      concat('|',
                                             position(),
                                             '|'
                                             )
                                      ),
                      '|'
                            )"/>
     <xsl:variable name="vNumNested"
       select="$vposNext - position() - 1"/>
     <xsl:copy>
       <xsl:copy-of select="@* | node()"/>
       <xsl:if test="$vNumNested > 0">
         <xsl:copy-of select=
           "following-sibling::record
                       [position() &lt;= $vNumNested]"/>
       </xsl:if>
     </xsl:copy>
  </xsl:template>

  <xsl:template match="record[not(@type='normal')]"/>
</xsl:stylesheet>
