MATLAB: Search an entire text file for a word

stringtext file

If i have a text file and am looking for the number of times a specific word appears in it, how would I go about doing that? I tried using the "contains" and "strfind" but they aren't working because its a text file not a string.

Best Answer

 content = fileread( 'MyTextFile.txt' ) ;

and then you can STRFIND or REGEXP or anything else on content, which is a char array.

I don't know what you mean by workspace file. Using proper terminology and examples that are valid matlab commands would help. Possibly you mean this:

v = [72 101 108 108 111 32 73 32 97 109 32 51 48 32 121 101 97 114 115 32 111 108 100 46];
s = char(v); %convert v into characters 
yearloc = strfind(v, 'years')

You only use regexp names option if you have search patterns of the form (?<NAME>PATTERN) in which case it searches for the pattern and puts matches into aa structure using NAME as the field name . In your case the pattern would be <TokenName> . Note that the <> after the ? are part of the syntax whereas the <> around TokenName are literal text .

Because the content matched by the pattern is returned and your content is static there is not much point using the syntax . You would be better off with no regexp option and so returning the match position .

However .... what would probably make more sense is to go directly to regexprep to do the search and replace without caring about the position .
