scanning text file and writing from .txt file

Hi,
I have this data in a txt file:
time = 0.0000E+00
 mat.#= 1012 inten= 0.0000E+00 kinen= 0.0000E+00 eroded_ie= 0.0000E+00 eroded_ke= 0.0000E+00
 x-mom= 0.0000E+00 y-mom= 0.0000E+00 z-mom= 0.0000E+00
 x-rbv= 0.0000E+00 y-rbv= 0.0000E+00 z-rbv= 0.0000E+00
 mat.#= 1013 inten= 0.0000E+00 kinen= 0.0000E+00 eroded_ie= 0.0000E+00 eroded_ke= 0.0000E+00
 x-mom= 0.0000E+00 y-mom= 0.0000E+00 z-mom= 0.0000E+00
 x-rbv= 0.0000E+00 y-rbv= 0.0000E+00 z-rbv= 0.0000E+00
 mat.#= 1014 inten= 0.0000E+00 kinen= 0.0000E+00 eroded_ie= 0.0000E+00 eroded_ke= 0.0000E+00
 x-mom= 0.0000E+00 y-mom= 0.0000E+00 z-mom= 0.0000E+00
 x-rbv= 0.0000E+00 y-rbv= 0.0000E+00 z-rbv= 0.0000E+00..............
I want to write a code which reads this text line by line and prints the 'mat.#' whose intern=0.0000E+00

I don't see anything where there's a string 'intern'. You mean 'inten'
I suppose???

If the above is the extent of the need, probably simplest to just parse
on the fly...

fid=fopen('yourfile','rt');
while ~feof(fid)
   l=fgetl(fid);
   if strmatch('mat.#',l)
     if sscanf(l(20:30),'%f')==0
       disp(l(1:12))
     end
   end
fid=fclose(fid);

Salt to suit, obviously...
