No!!
you can only refer to nodeset in the xsl:for-each... you are tryin to refer to a variable through $myvar .. which is wrong...

if you wanted to do something in the lines of picking up all the items whose name is "DEC" or what ever, then you may want to try the following..
Your XML:
<?xml version="1.0" ?>
<collection>
<intro>My Computer Collection</intro>
<item>
<manufacturer>DEC</manufacturer>
<model>MicroVAX 3100-30</model>
<opsys>OpenVMS 5.5-2</opsys>
<cpu>25MHz</cpu>
<memory>unknown</memory>
<enclosure>BA42-B</enclosure>
<notes>none</notes>
</item>
<item>
<manufacturer>COMPAQ</manufacturer>
<model>COMPAQ II</model>
<opsys>OpenVMS 5.5-2</opsys>
<cpu>KA630</cpu>
<memory>unknown</memory>
<enclosure>BA23 rackmount</enclosure>
<notes>This is my first VAX which I hope to get running
with OSU (=DECthreads)</notes>
</item>
</collection>


XSL:

( to select the model of an item with the manufacturer as DEC or COmpaq or whichever u choose ... i have only selected the Model... you may select which ever u want to)

<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<xsl:for-each select="/collection/item[manufacturer = 'DEC']">
<xsl:value-of select="model"/>
<br></br>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>

In the above style sheet you are specific about the manufacturer value.. you can change that value to 'Compaq' to get all the items whose manufacturer is Compaq..

HTH ( if this is what you want )

Subject:  <xsl:for-each select="$myvar">

I am trying to do the operation as described in the subject
line but am getting "Sablotron Error (48):
expression is not a node set".

The value of the variable is "item" which is the same as if
I used "<xsl:for-each select="item">" So why
doesnt this work?

What I had hoped to do with this is allow the user to
have control what is displayed in an XML file. For
instance with the XML file below I would like to display
only DEC machines, or only Compaq, or only IBM.

XML file sample...

<?xml version="1.0" ?>

<collection>
        <intro>My Computer Collection</intro>
<item>
        <manufacturer>DEC</manufacturer>
        <model>MicroVAX 3100-30</model>
        <opsys>OpenVMS 5.5-2</opsys>
        <cpu>25MHz</cpu>
        <memory>unknown</memory>
        <enclosure>BA42-B</enclosure>
        <notes>none</notes>
</item>

<item>
        <manufacturer>DEC</manufacturer>
        <model>MicroVAX II</model>
        <opsys>OpenVMS 5.5-2</opsys>
        <cpu>KA630</cpu>
        <memory>unknown</memory>
        <enclosure>BA23 rackmount</enclosure>
        <notes>This is my first VAX which I hope to get running
        with OSU (=DECthreads)</notes>
</item>
 . . . . and so on...

By the way, I am not too sure the XML file is formatted very
well. This is just a test setup. Can anyone suggest a better way to
do it? I can't seem to see anything in the archives. I am
using php with Sablotron and doing this all on the server end.

Thank you,
