Is there any way to extract text from .tex file?

I am writing a program to count words in a file. I am facing problems while parsing .tex files.

This code need to go on a website where it has to count words from the file that is being uploaded. I have managed to do it but I am looing for some better solutions

case "application/x-tex": // Avoid words with '\' and count
            Scanner sc1;
            try {
                sc1 = new Scanner(new URL(URLPath).openStream());
                while (sc1.hasNext()) {
                    String str = sc1.next();
                    if (!str.contains("\\")) {
                        System.out.print(str + " ");
                        wordCount++;
                    }
                }
                sc1.close();
            } catch (IOException e) {
                System.out.println("There was a problem while reading File on the URL");
                break;
//              e.printStackTrace();
            }
            if (wordCount <= 0) {
                System.out.println("Total count is " + wordCount
                        + ". The uploaded File is either empty or it consists of Images only");
            } else {
                System.out.println("");
                System.out.println("**********");
                System.out.println("Word Count: " + wordCount);
                System.out.println("**********");
                System.out.println("");
            }
            break;

I am expecting a String output which I could further use to count words.
