concatenate a string

I am trying to concatenate a list of fields.

this code produces a list of the fields, as one long string:

<xsl:for-each
select="BusinessObject/Export/Table/Record[1]/Parameter/@Name">
	<xsl:value-of select="."/>
</xsl:for-each>

like this :
INFO_RECMATERIALMAT_GRPVENDORDELETE_INDCREATED_ATCREATED_BYSHORT_TEXTSORTED_
BYPO_UNIT


what i need is this :

<var
name=fieldList="INFO_REC,MATERIAL,MAT_GRP,VENDOR,DELETE_IND,CREATED_AT,CREAT
ED_BY,SHORT_TEXT,SORTED_BY,PO_UNIT">

can anyone give me a code snippet to help me get there ?

thanks,
paul
