Parsing a TCL List with java

I am writing a new client for a client/server application. The server was written in TCL and returns responses in TCL list format, in some cases as nested lists.

Ex: {data { bob frank ted } 6 7}

What I would like to do is pull out the nested part of the list {bob frank ted} and turn it into a java array {bob, frank, ted} and the remaining members into a second array {data,8,7}

I have looked at regular expressions, the stringtokenizer, and various parsing classes - is there a single clean way of doing this?

TIA

Darrell

Try something like this:import java.util.regex.Matcher;

import java.util.regex.Pattern;

class Main {

public static void main(String[] args) {

String line = "{data { bob frank ted } 6 7}";

String inner = myGroup(line);

String outer = line.replace(inner, "");

System.out.println(line+"\n=\n"+inner+"\n+\n"+outer);

}

static String myGroup(String s) {

Pattern pattern = Pattern.compile("\\{([^{}]*?)\\}");

Matcher matcher = pattern.matcher(s);

return matcher.find() ? matcher.group() : null;

}

}

Or perhaps: http://tcljava.sourceforge.net/docs/website/index.html
