[xsl] Msxml4 node-set and Filters bug

["Henk J Meulekamp" <henkmeulekamp@xxxxxxxxx>]

Hello group,

I'm having a problem (possible bug) with msxml4 parser and the node-set
ext. function. I'm generating a small RTF to reduce the number of loops
and thereby the process time.

I tried to cut-out a small part from my styleseheet. The node-set
function itself is working, but after that some things stop working.

Below you find my source XML, I cut out most not needed parts, it then
generate a nodeset with the xml below:
<!----------------------------------->
<xsl:variable name="learningobjects">
		<xsl:element name="learningobjects">
		<xsl:for-each
select="/root/data/COURSE/RESULT[not(@IDLEARNINGOBJECT  =
preceding::node()/@IDLEARNINGOBJECT)]">
			<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:attribute>
			</xsl:element>
		</xsl:for-each>
			</xsl:element>
	</xsl:variable>

It generates this: 
<!----------------------------------->
  <learningobjects>
  <lo id="46" cname="Deze training" /> 
  <lo id="47" cname="Gedachtevorming" /> 
  <lo id="48" cname="Theorie" /> 
  <lo id="50" cname="Transferdag" /> 
  </learningobjects>


I've then replaced this part below which was working well:
<!----------------------------------->
<xsl:for-each select="/root/data/COURSE/RESULT[not(@IDLEARNINGOBJECT  =
preceding::node()/@IDLEARNINGOBJECT)]">
	<xsl:variable name="lo" select="@IDLEARNINGOBJECT"/-->
	
-<xsl:value-of select="$lo"/>-<xsl:value-of
select="/root/data/COURSE/RESULT[@IDLEARNINGOBJECT=
$lo]/@CLEARNINGOBJECT"/>
   		</xsl:for-each>		



<!-- 
The part above show me numbers and names


The new code looks like this below, usign the node-set ext. fucntion.-->


<xsl:for-each
select="msxsl:node-set($learningobjects)/learningobjects/lo"><xsl:variab
le name="lo" select="@id"/>
 					-<xsl:value-of
select="$lo"/>-<xsl:value-of
select="/root/data/COURSE/RESULT[@IDLEARNINGOBJECT=
$lo]/@CLEARNINGOBJECT"/>

		      <!--<xsl:value-of select="@cname"/>-->&#160;

   		</xsl:for-each>		
<!-- 
It doesn't show me the names anymore.. The statement:<xsl:value-of
select="$lo"/> is still showing the same Id list, but 
<xsl:value-of select="/root/data/COURSE/RESULT[@IDLEARNINGOBJECT=
$lo]/@CLEARNINGOBJECT"/>

Doesn't show me the names anymore. It looks like the part in between []
arent doeibng anything anymore. I can put [@IDLEARNINGOBJECT= 46] in it,
but even then it doesn't give me a name ( value of @CLEARNINGOBJECT).

Is this a known bug in MSXML4?
