ok, here is the part that i'm interested in:

<labels><label catno="MINUS 07" name="M_nus"/><label catno="PLUS8076" name="Plus 8 Records Ltd."/></labels>

and this is part of my script for xml part above:

outputto "CATALOG"
findinline "<labels>"
do
    findinline "catno=\""
    sayuntil "\""
    say ", "
    findinline "/>"
while "<label "

and here is what i get
"MINUS 07, PLUS8076, "
how do i remove unwanted comma and space (", ") at the end?

thanks, in advance.
