Ok.. .the following is working great, but I am using != operand.  How
do you write the below match using not() and achieve same results?

<xsl:template match="@* | node()">
  <xsl:copy>
	<xsl:apply-templates select="@*"/>
	<xsl:apply-templates />
  </xsl:copy>
</xsl:template>

<xsl:template match="*[@cat!='BLUE']" />
