Removing text from a string file(java)

Question

I want to remove all the text between < and >. I am trying to get familiar with regular expressions so my code for this looks like:

line.replaceAll("<.*?>","");

I am replacing it line by line using a recursive method.

This is the whole method to clear things up. I am getting the same input and output.

    // recursively goes through the string and removes anything surrounded by "< >"
public static void removeTags(String line) {
    line.replaceAll("<.*?>","");
    cleanString = cleanString + line;
    if (sc.hasNext()) {
        removeTags(sc.nextLine());
    }
}

Strings are immutable. replaceAll doesn't affect original string but creates new one. — Pshemo

Can you provide any example of input and output you getting ? — apgp88

Oh okay. Pshemo has it. My problem is that I am essentially creating a new blank string — NIcholas Tremblay

You have to store your resulting string, so change this:

line.replaceAll("<.*?>","");

To

line = line.replaceAll("<.*?>","");
