RE: [xsl] Select nodes with an attribute but not all the nodes

["Patrick Lachance" <plachance@xxxxxxxxx>]

Or if we can't use XSLT 2.0 ...

	<xsl:template match="level2[not(@attachpart)]">
        <record>
           <name>{name}</name>
            <attachingPart>
              <xsl:call-template name="attachingparts"/>
            </attachingPart>
        </record>
	</xsl:template>
	<xsl:template name="attachingparts">
	  <xsl:param name="current"
select="following::*[position()=1]"/>
        <xsl:param name="first" select="1"/>
        <xsl:if test="current/@attachpart">
          <xsl:if test="$first=0">
      	<xsl:text disable-output-escaping="yes">&#160;</xsl:text>
          </xsl:if>
          <xsl:value-of select="current/number"/>
          <xsl:call-template name="attachingparts">
		<xsl:with-param name="current"
select="current/following::*[position()=1]"/>
		<xsl:with-param name="first" select="0"/>
	    </xsl:call-template>
        </xsl:if>
      </xsl:template>

.. I think it could work

It's dangerous to use the word "when" in your problem statement because
it suggests you are thinking in terms of order of execution.

What you've got here is a positional grouping problem:

<xsl:for-each-group select="level2"
group-starting-with="*[not(@attachpart)]">
<record>
  <name><xsl:value-of select="name"/></name>
  <attachingPart>
    <xsl:value-of select="current-group()[@attachpart]/number"/>
  </attachingPart>
</record>
</xsl:for-each>
