Split variables

Hi,

I've got a variable that contains following string:
123,abc,456,def,

I want to have the string putted into separate variables like this:

<xsl:variable name="var1">123</xsl:variable>
<xsl:variable name="var2">abc</xsl:variable>
<xsl:variable name="var3">456</xsl:variable>
<xsl:variable name="var4">def</xsl:variable>

Is it possible to split a variable in to new variables?
