Help in Strcut MATLAB , please !

I have this code: for build struct in Matlab to read text file :

when i running this code gave me error because the third line of the text data file ( c) , is not arranged in the same style as others text lines data file; please i need read this text file as struct with ignore reading the third data line in text file or any line similar to the third data line has not appropriate arrangement as other data lines in that text file

 c={'413733000: system.cpu15.icache: ReadReq [10574:10577] IF hit state: 5 (S) valid: 1 writable: 0 readable: 1 dirty: 0 tag: 8',...

     tline(n)= strlength(c(n));
    if (tline(n) >= 123)|| (tline(n) <= 126)
    str=c{n};
           idx=strfind(str,':');

I recommend using regexp() to parse the file, using the named token feature.
