Replace invalid characters from HTML file with valid ones and save the file.

Hi all,

I am currently working on a script for editing the html file. (MATLAB 2013b)

The HTML file has some invalid characters like m³. And I want replace these characters e.g. m³ to m3.

I am able to read the html file as a cell of 4405x1 cell. Here, I am not able to use strrep command. Following is the code:

fid = fopen('C0TH_Doc_main.html','r');

MyText = textscan(fid,'%s','delimiter','\n');

strrep(MyText, 'm³', 'm3');

% rewrite the file

fid = fopen('C0TH_Doc_main.html','wt');

fprintf(fid,'%s\n',MyText);

fclose(fid);

Following is error screenshot

Once all the characters are replaced, I want to preferably save it to the same HTML file or atleast wirte it into a new txt file.

Please provide any hints or other ways to complete this task.

Thank you in Advance

MyText = strrep(MyText{1}, 'm³', 'm3');

Thank you Mr. Roberson. It worked.

Further to write into an HTML file I used following code. Perhaps in future this will helpe someone. Following is the complete code:

By the way you could consider using regexprep to do all the replacements in one call.
