How to substitute variable value?

[Kesi]

I have this xslt, how to substitute the variable value between element name?

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
 xmlns:x="cds_dt"> <xsl:output omit-xml-declaration="yes" indent="yes"/> <xsl:strip-space elements="*"/> 
<xsl:template match="node()|@*"> 
<xsl:copy> 
<xsl:apply-templates select="node()|@*"/> 
</xsl:copy> 
</xsl:template> 

<xsl:template match="customfields"> 
<xsl:copy> 
<xsl:apply-templates select="child::node([not(self::customfield)]"/> 
</xsl:copy> 
</xsl:template>

<xsl:apply-templates select="customfield"/>  
<xsl:template match="customfield"> 
<xsl:for-each select=".">
<xsl:variable name="temp" select="./customfieldname"/>     <xsl:variable name="temp2"select="../customfieldvalue"/> <xsl:element name="{$temp}"><xsl:value-of select="$temp2" /></xsl:element> 
</xsl:for-each> 
</xsl:template> 
</xsl:stylesheet>
