Is there any way to process the nodes from the
<xsl:copy-of select=""/>

Not in the usual way. But anyway, this is not your problem, see below.

<Box name="iconsarea">
<xsl:copy-of select="$strTopLeftIcon"/>


I want to process <image> using that $strTopLeftIcon..
Is it possible?

This should be very possible, provided that $strTopLeftIcon is a nodeset.

I am using XSLT version 1.0.. it gives the following

(Location of error unknown)XSLT Error
(org.apache.xpath.XPathException): Can not
 convert #RTREEFRAG to a NodeList!

The error message states that this is not a nodeset (I presume that we are talking about $strTopLeftIcon here ). Since you have not shown us how $strTopLeftIcon is created, it is a little hard to tell what may be wrong.

My guess is that you have created the variable like this:

<xsl:variable name="strTopLeftIcon">
 <!-- The expression that generates the value of the variable here -->

This variable (in XSLT 1.0) creates a Result Tree Fragment, which is not a nodeset.

You need to use this construct:
<xsl:variable name="strTopLeftIcon" select="YourExpressionHere"/>

This will create a nodeset.

If it is not possible to have such a construct, you will have to use an extension function, that can take a tree fragment and convert it into a nodeset. The exact syntax is processor dependent, but most processors have this extension.

Any solution or suggestion..

See above :-)
