[xsl] Multiple expressions in if conditons

["Thangavelu Srinivasan" <vasantry@xxxxxxxxx>]

Hi Folks

I am using xslt 1.0. I am facing the problem in if conditions. Any
suggestions are welcome

My XSL
<xsl:for-each select="//*">
<xsl:variable name="code" select="name()" />
<xsl:variable name="value" select="." />
<xsl:if test= "$code != ('state_results') or ('game_results')">
<subject_code><xsl:value-of select="name()"/></subject_code>
<subject_value><xsl:value-of select="."/></subject_value>
<xsl:text disable-output-escaping="yes">&#10;</xsl:text>
</xsl:if>
</xsl:for-each>

I am not able to test multiple value using if condition. i want to
confirm whether my if conditon is correct for checking multiple value
