典型使用方法如下：

<!-- 名为copy_config的函数，参数为confignodes　。　注意：函数一定要写在调用它地方的前面 -->

<xsl:template name="config_config match="/">

<xsl:param name="confignodes" />

<http-service>

<!--拷贝一个元素及它的子元素-->

<xsl:copy-of select="$confignodes/web-container/access-log"/>

<!-- 拷贝本元素及其属性，不包括子元素 -->

　　　 <xsl:value-of select="'&lt;availability-service '" disable-output-escapting="yes" />

<xsl:for-each select="$confignodes/availability-service/@*">

<xsl:value-of select="name()" />="<xsl:value-of select="." />"

</xsl:for-each>

<xsl:value-of select="'/&gt;'" disable-output-escapting="yes" />

</http-service>

</xsl:template>

<xsl:template match("/">

<xsl:for-each select="//config">

<config>

<!-- 调用名为copy_config的函数，传进的参数为confignodes-->

<xsl:call-template name="copy_config">

<xsl:with-param name="confignodes" select="." />

</xsl:call-template>

</config>

</xsl:for-each>

</xsl:template>

使用XSL API对ＸＭＬ进行转换：
