Java: how to read with scanner using delimiters "<" or ">" or "><"

Question

Good morning,

I want to read a .txt file using Scanner in this format:

Scanner scan = < trains>< intercity>< from>< stationname>

Question: how to seperate the tokens such that I will remain with tokens

trains intercity from stationname

such that I can use scan.next() ?

Thank you very much!

In case you're thinking of using Scanner to read an XML file: don't. — Klitos Kyriacou, Oct 26 '17 at 10:55

You can make a Scanner instance from the String and use a regex for the delimiter. Following is an example:

    String a = "< trains>< intercity>< from>< stationname>";
    Scanner scanner = new Scanner(a);
    scanner.useDelimiter(Pattern.compile("\\<|\\>|\\>\\<"));
    while(scanner.hasNext()) {
        System.out.print(scanner.next());
    }
    scanner.close();lose();

Output:

 trains intercity from stationname
