How to remove empty lines from an updated XML?

Question

So what I'm doing is, I'm finding and deleting some tags from an XML. After deleting, those tags are getting replaced by blank space, which actually ain't effecting the XML but it can cause problem when I delete a large number of tags.

Any working way to achieve this?

Thanks in Advance.

Here is the link of the answer I found here but it's not working

This should work:

public static void main(String[] args) {

    Scanner file;
    PrintWriter writer;

    try {

        file = new Scanner(new File("src/myXml.xml"));
        writer = new PrintWriter("src/myXml2.xml");

        while (file.hasNext()) {
            String line = file.nextLine();
            if (!line.isEmpty()) {
                writer.write(line);
                writer.write("\n");
            }
        }

        file.close();
        writer.close();

    } catch (FileNotFoundException ex) {
        Logger.getLogger(Test.class.getName()).log(Level.SEVERE, null, ex);
    }
}

But it didn't work for XML. I guess, XML follows something else for this. — Amrit Kr Lama, Feb 28 '17 at 10:06
