RE: Concatenate element values based on another key element

Here's a partial solution.  It doesn't iterate through the integer values,
but it does collect
all the text for each value pretty well.  I gotta go home now, my wife is
wondering where the
heck I am.

<?xml version="1.0" encoding="ISO-8859-1" ?>
<xsl:stylesheet
  version="1.0"
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

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

  <!-- Set up a key that finds recs by some_id value -->
  <xsl:key name="idKey"
    match="rec"
    use="some_id" />

  <xsl:template match="/test">

    <!-- Unfortunately I haven't solved the iteration (recursion?)
         problem here -->
    <xsl:call-template name="doOneIdValue">
      <xsl:with-param name="idValue" select="1" />
    </xsl:call-template>

    <xsl:call-template name="doOneIdValue">
      <xsl:with-param name="idValue" select="2" />
    </xsl:call-template>

    <xsl:call-template name="doOneIdValue">
      <xsl:with-param name="idValue" select="3" />
    </xsl:call-template>
  </xsl:template>

  <xsl:template name="doOneIdValue">
    <xsl:param name="idValue" />
    <rec>
      <some_id><xsl:value-of select="$idValue"/></some_id>

      <some_text>
        <xsl:apply-templates mode="string" select="key('idKey', $idValue)"
/>
      </some_text>

    </rec>
  </xsl:template>

  <xsl:template mode="string" match="rec">
    <xsl:value-of select="some_text" />

  </xsl:template>

</xsl:stylesheet>
