You can do something like this:

<xsl:for-each select="element">     <xsl:value-of select="whatever" />     <xsl:if test="position() != last()">, </xsl:if> </xsl:for-each>

The position() function returns the index of the current element in the for-each context, and last() returns the index of the last element.

The Conditional Processing with xsl:if section of the XSLT documentation provides more information about this example.

In XSLT 2.0 you can use the string-join function.

<xsl:value-of  select="string-join(/element/whatever, ',')"/>
