awk '/<nam>/ {L=1} /<a1>/ {L=0} /<\/var>/ && L {print "<a1>.</a1>"} 1' input.xml

Code:
awk     '/<nam>/                {L=1}                   # if a line contains <nam>, keep that fact in variable L
         /<a1>/                 {L=0}                   # if then <a1> occurs, no action necessary, reset L
         /<\/var>/ && L         {print "<a1>.</a1>"}    # if end of section and L still set, print missing string.
                                                        # you might want to reset L as well to be on the safe side
         1                                              # print normal lines from file
        ' file
