MATLAB: If Statement for text files

if statement

Greetings,
I have this cell array that displays this text:
urlwrite('http://weather.noaa.gov/cgi-bin/fmtbltn.pl?file=forecasts/marine/coastal/am/amz725.txt','Water_Coastal_Southern_Puerto_Rico_Out.txt'); % URL from forecast web page
fid=fopen('Water_Coastal_Southern_Puerto_Rico_Out.txt');
y=fgetl(fid);
data = textscan( fid, '%s', 'Delimiter', '');  %read the entire file as strings, one per line.
fclose(fid);
out = regexprep( data{1}, '<[^>]+>', '' )  %remove the HTML
n=length(out);
out = 
      'CWFSJU'
      'COASTAL WATERS FORECAST'
      'NATIONAL WEATHER SERVICE SAN JUAN PR'
      '1024 PM AST MON JUL 9 2012'
      'PUERTO RICO AND U.S. VIRGIN ISLANDS WATERS'
      ''
      'AMZ725-101500-'
      'COASTAL WATERS OF SOUTHERN USVI VIEQUES AND EASTERN PUERTO RICO OUT'
      '10 NM-'
      '1024 PM AST MON JUL 9 2012'
      'REST OF TONIGHT'
      'EAST WINDS 12 TO 16 KNOTS. SEAS 3 TO 4 FEET.'
      'ISOLATED SHOWERS. '
      'TUESDAY'
      'EAST WINDS 12 TO 16 KNOTS. SEAS 3 TO 4 FEET. HAZE.'
      'ISOLATED SHOWERS. '
      'TUESDAY NIGHT'
      'EAST NORTHEAST WINDS 13 TO 16 KNOTS. SEAS 3 TO'
      '4 FEET. HAZE. ISOLATED SHOWERS. '
      'WEDNESDAY'
      'EAST NORTHEAST WINDS 12 TO 15 KNOTS. SEAS 3 TO 4 FEET.'
      'HAZE. ISOLATED SHOWERS. '
      'WEDNESDAY NIGHT'
      'EAST NORTHEAST WINDS 12 TO 15 KNOTS. SEAS 3 TO'
      '4 FEET. HAZE IN THE EVENING. SCATTERED SHOWERS THROUGH THE NIGHT. '
      'THURSDAY'
      'EAST WINDS 8 TO 13 KNOTS. SEAS 2 TO 4 FEET. ISOLATED'
      'SHOWERS. '
      'FRIDAY'
      'EAST SOUTHEAST WINDS 11 TO 16 KNOTS. SEAS 3 TO 5 FEET.'
      'ISOLATED SHOWERS. '
      'SATURDAY'
      'EAST WINDS 13 TO 18 KNOTS. SEAS 4 TO 6 FEET. ISOLATED'
      'SHOWERS. '
      [1x165 char]
I want to generate an "if" statement that takes certain lines to display it on  the Command Window. For example,
if (the text line starts with 'REST… display the lines:
 'REST OF TONIGHT'
    'EAST WINDS 12 TO 16 KNOTS. SEAS 3 TO 4 FEET.'
    'ISOLATED SHOWERS.'
Thank you for your time.

index = find(strncmpi(out, 'Rest', 4));
fprintf('%s\n', out{index + 1});
