<xsl:value-of select="/root/data/COURSE/RESULT[(_at_)IDLEARNINGOBJECT=
$lo]/@CLEARNINGOBJECT"/>
your for-each has moved you into the node set generated from teh result
tree fragment, this has its own root node and that xpath is taken
relative to that, not relative to the original document.
instead do
<xsl:variable name="originaldoc" select="/"/><xsl:for-each
select="msxsl:node-set($learningobjects)/learningobjects/lo">....
<xsl:value-ofselect="$originaldoc/root/data/COURSE/RESULT......

PS
<xsl:element name="lo"><xsl:attribute
name="id"><xsl:value-of select="@IDLEARNINGOBJECT"/></xsl:attribute>
<xsl:attribute
name="cname"><xsl:value-of select="@CLEARNINGOBJECT"/>
</xsl:element>
is a very long winded way of writing
<lo id="{(_at_)IDLEARNINGOBJECT}" cname="{(_at_)CLEARNINGOBJECT}"/>
which is totally equivalent.
