Re: problem with key

Thank you David and Dimitre,

You are both right.  Thank you.  I would have responded sooner but it took
me some time to find a bug that caused the file to grow.  I now pass a
/level/ parameter to facilitate deleting duplicates. Here is working XSLT

<xsl:param name="level"></xsl:param>
    <xsl:output method="xml" indent="yes" />
    <xsl:variable name="lookupDoc" select="document('step2.xml')"/>

    <xsl:key name="SemanticDomainByParent" match="CmSemanticDomain"
use="@parent" />

    <xsl:template match="CmSemanticDomain[@level=$level]"/>

    <xsl:template match="line[@tag='gd']">
        <xsl:variable name="parentSD" select="parent::*/@sd"/>
        <SubPossibilities>
            <xsl:copy-of select="key('SemanticDomainByParent', $parentSD,
$lookupDoc)"/>
        </SubPossibilities>
    </xsl:template>

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

I ended up building the hierarchy one transformation at a time. The
inserted text has tag = 'gd' which triggers the insertion the next time
around.  So multiple application of the same XSL does the trick.

I started by creating a file with just the 0 level of hierarchy. I then
inserted the correct information from an external file at the correct
location.  There may be easier ways of doing this.  But this is something
that I can explain fairly easily to novices.  You continue until you have
processed all the levels.

Thank you again for your help.
