According to section 11.1 of XSLT 1.0,[1] "An operation is permitted on a
result tree fragment only if that operation would be permitted on a string
(the operation on the string may involve first converting the string to a
number or boolean)." So in standard XSLT, you can't do it. To be able to
access the nodes in a result tree fragment and directly manipulate them,
you need to use the node-set extension function. Something like the
following should work:
<xsl:variable name="category_defs"
xmlns:exslt="http://exslt.org/common";>
<xsl:for-each select="exslt:node-set($category_defs1)/node()" >
<xsl:copy>
<xsl:attribute name="mode">1</xsl:attribute>
</xsl:copy>
</xsl:for-each>
<xsl:for-each select="exslt:node-set($category_defs2)/node()" >
<xsl:copy>
<xsl:attribute name="mode">2</xsl:attribute>
</xsl:copy>
</xsl:for-each>
</xsl:variable>
I hope that helps.
Thanks,
Henry
