I have a sgml file that has some custom tags. I used regular expression to read the data between tags but due to missing loop it is only printing the first set of values. Can some one help me writing proper loop for the same so that i get all set of values for those tags.

my sgml data looks like below. I want to read data between tags TOPICS and BODY. I also attached my matlab code.

<TITLE>BAHIA COCOA REVIEW</TITLE>
<DATELINE>    SALVADOR, Feb 26 - </DATELINE><BODY>Showers continued throughout the week in
the Bahia cocoa zone, alleviating the drought since early
January and improving prospects for the coming temporao,
although normal humidity levels have not been restored,
Comissaria Smith said in its weekly review.
    The dry period means the temporao will be late this year.
    Arrivals for the week ended February 22 were 155,221 bags
of 60 kilos making a cumulative total for the season of 5.93
mln against 5.81 at the same stage last year. Again it seems
that cocoa delivered earlier on consignment was included in the
arrivals figures.
    Cake sales were registered at 785 to 995 dlrs for
March/April, 785 dlrs for May, 753 dlrs for Aug and 0.39 times
New York Dec for Oct/Dec.
    Buyers were the U.S., Argentina, Uruguay and convertible
currency areas.
    Liquor sales were limited with March/April selling at 2,325
and 2,380 dlrs, June/July at 2,375 dlrs and at 1.25 times New
York July, Aug/Sept at 2,400 dlrs and at 1.25 times New York
Sept and Oct/Dec at 1.25 times New York Dec, Comissaria Smith
said.
    Total Bahia sales are currently estimated at 6.13 mln bags
against the 1986/87 crop and 1.06 mln bags against the 1987/88
crop.
    Final figures for the period to February 28 are expected to
be published by the Brazilian Cocoa Trade Commission after
carnival which ends midday on February 27.
