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

Question

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.

// Trigger perl script
URL website = new URL(URLPath);
Path path = Paths.get("myfile.tex");
bufferFiles.add(new File("myFile.tex"));
try (InputStream in = website.openStream()) {
Files.copy(in, path, StandardCopyOption.REPLACE_EXISTING);
}
URL texcount = new URL("https://papertrue.s3.us-west-1.amazonaws.com/draft/77e3c992-b70f-4711-8b9b-eaf390617bb8");
Path path1 = Paths.get("texcount.pl");
bufferFiles.add(new File("texcount.pl"));
try (InputStream in = texcount.openStream()) {
Files.copy(in, path1, StandardCopyOption.REPLACE_EXISTING);
}
wordCount = 0;
Process process;
try {
process = Runtime.getRuntime().exec("/etc/papertrue/texcount.pl myfile.tex");
InputStream is = process.getInputStream();
InputStreamReader isr = new InputStreamReader(is);
BufferedReader br = new BufferedReader(isr);
String line;
while ((line = br.readLine()) != null) {
String tem[] = line.split(":\\s");
log.debug(tem[tem.length - 1]);
try {
wordCount += Integer.parseInt(tem[tem.length - 1]);
} catch (Exception e) {
}
}
process.waitFor();
if (process.exitValue() == 0) {
log.debug("Command Successful");
} else {
log.debug("Command Failure");
}
log.debug(wordCount);
} catch (IOException e) {
log.debug("There was a problem while reading File on the URL");
e.printStackTrace();
break;
