XSL中使用if判断

有时需要根据情况显示数据，xsl中可以使用if来做判断：

<xsl:for-each select="ROOT/ALOOP/FRPARA1/LOOP/FPARA1"> 			
 <xsl:if test="MCRECORD[position() =2]/ILOOP/MC/TR/TD/MCCONTENT/CONTENT = '名字典故'">
		<li>
			<span class="date">
				<a href="{MCRECORD/ILOOP/MC/TR/TD/MCCONTENT/CONTENTLINK}" target="_blank">详情</a>
			</span>
			<a href="{MCRECORD/ILOOP/MC/TR/TD/MCCONTENT/CONTENTLINK}" target="_blank">
				<xsl:value-of select="substring(MCRECORD/ILOOP/MC/TR/TD/MCCONTENT/LCONTENT,1,30)"/>
			</a>
		</li>
</xsl:if>
</xsl:for-each>
