loop through comma seperated values

Dear All,

I have XML document with an element having comma seperated values as below
<RowKey>JAN,FEB,MAR,APR,MAY,JUN,JUL,AUG,SEP,OCT,NOV,DEC,YTD</RowKey>

I need to loop through the values. I tried to replace the comma","
with "><" and used the variable in For each as below.
<xsl:for-each select="msxsl:node-set($ColHead)">
	<xsl:value-of select="."/>
</xsl:for-each>
Note: $ColHead contains the comma seperated values.


But no luck. Any help ?
