Hi Yao,
I assume that you have extracted the text from a pdf file which is saved as a string variable. You can convert the string to a character array (convertStringsToChars) and count the words and lines.
Assume that
- Every word ends with a space
- Every line ending has a carriage return and line feed
Using the built-in MATLAB example, the following program gives you the total line count and word count in the section of the file.
str = extractFileText("exampleSonnets.pdf");
ii = strfind(str,"II");
iii = strfind(str,"III");
start = ii(1);
fin = iii(1);
stringText = extractBetween(str,start,fin-1);
B = convertStringsToChars(stringText);
% Define the space character and end-of-line character
SpaceCharacter = B(3);
CarraigeReturnCharacter = B(4);
lineCount = 0;
wordCount = 0;
i = 1;
while i <= length(B)
if B(i) == CarraigeReturnCharacter
lineCount = lineCount + 1; % Total line count
end
if B(i) == SpaceCharacter
wordCount = wordCount + 1; % Total Word Count
end
i = i + 1;
end
