Question

I connected to a site using URLConnection and the result I’m looking for is the url inside these parenthesis: callback_request("https://secure.runescape.com/m=displaynames/s=bOVZmsrjbNQzntbDei*324JUo*3ozJ7hR*h1KNlxc6kPaBeKCBrdKIxD*edhi4qH/check_name.ws?displayname=" + escape(text), handleResult);

The problem I’m having is the : s=bOVZmsrjbNQzntbDei*324JUo*3ozJ7hR*h1KNlxc6kPaBeKCBrdKIxD*edhi4qH is random each time–it’s the session.

How can I use a regex expression to scan the page and look for https://secure.runescape.com/m=displaynames/(random_session_id)/check_name.ws?displayname=?

Try this:

import java.util.regex.Pattern;

public class Regex {
    public static void main(String[] args) 
    {
        Pattern p = Pattern.compile("https://secure\\.runescape\\.com/m=displaynames/.*/check_name\\.ws\\?displayname=\\?");
        System.out.println(p.matcher("https://secure.runescape.com/m=displaynames/s=bOVZmsrjbNQzntbDei*324JUo*3ozJ7hR*h1KNlxc6kPaBeKCBrdKIxD*edhi4qH/check_name.ws?displayname=?").find());
    }
}
