How can i parse the given string?

Question

Hi guys i have been given a task to parse a string which will be coming from the server.

The string looks like:

<first name=$Jon$ last name=$Doe$/><first name=$Doe$ last name=$Jon$/><first name=$r$ last name=$k$/>

and the output needed is:

first name: Jon
last name: Doe
-------------------
first name: Doe
last name: Jon
-------------------
first name: r
last name: k
-------------------

i.e.,

key: value

I have done some simple text-parsing which included a simple delimiter like a $ or a %. but in this case i don't understand how to parse the text. Your help will be very helpful.

Answer 1

        Matcher keys = Pattern.compile("[<\\s)](.*?)[=]").matcher(string);
        Matcher values = Pattern.compile("[$](.*?)[$]").matcher(string);
        while(keys.find() && values.find()) {
            System.out.println(keys.group(1)+" : "+values.group(1));
        }
