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.

Try to split the data in substrings (like ) and the parse this this substrings — Narkha, Sep 19 '13 at 11:01
It seems like you're missing some basic knowledge about programming. What exactly is your problem? — Boy, Sep 19 '13 at 11:01

replace $ in xml string from server with ", load it as xml document, use XPath or some other mechanism to parse the information you need

There can be multiple ways to reach to the solution

Can use XSLT with Java. (Java provides apis like TransformerFactory, Transformer etc.)
Can use XSLT in IDE like eclipse. Several plugins available.

Can check this out www.vogella.com/articles/XSLT/article.html

can use unix script to do the same.

It is not the exact solution to your problem but solutions you can try. Similarly there can be many other ways for sure.

        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));
        }

i think m.find() in while is actually values.find() – Rushi Sep 19 '13 at 11:17
It works, thanks. I will have to work on **Matcher** and **Pattern** i guess. – Rushi Sep 19 '13 at 11:23
