Hi all,
Could you find the exact string match in the input file?
I am unable get exact match of the sting in the read file, i tried this using strfind command, but could not get what i want.
My case is as follows,
Input file has data, out of it I need to find specific exact string in the file, suppose my input file name is input_data.txt and the data
>> txt = fileread('input_data.txt')
>> txt =
'var_abc = 12;
var_abcd = 20;
var_xyz = 30;
var_xy = 152;
var_abcxyz = 142;'
In this data i need to confirm specific string is present or not in the file.
Suppose i want to search the string var_ab in the file it's giving me
strfind(t, 'var_ab')
ans =
1 16 62
but it is finding strings within other strings, here I need to search only exact specific string var_ab
If the specificr string is present in the file, it should return true/value/string else an empty/false output
i.e
strfind(t, 'var_ab')
ans =
[]
-Thanks

Hi Bhaskar,
how about including space in the reference string? For your case, 'var_ab ', not 'var_ab'.
I wonder if I could catch your point.
HTH.
