求一个正则问题

[小白晒太阳]

var data4 = eval('('+'[{"device":["28.0","72.0"]}]'+')');

我想获取里面的28.0和72.0该如何获取

  Pattern pattern = Pattern.compile("var data4 = eval('('+'[{\"device\":[\"(.*?)\",\"(.*?)\"]}]'+')');");
        Matcher matcher = pattern.matcher(html);
        while (matcher.find()) {
            System.out.println(matcher.group(1));
            System.out.println(matcher.group(2));
        }

我的代码这么写的，取不到结果。。求大神指点。。

Pattern pattern = Pattern.compile("var data4 = eval\\('\\('\\+'\\[\\{\"device\":\\[\"(.*?)\",\"(.*?)\"\\]\\}\\]'\\+'\\)'\\);");

import java.util.regex.*;

public class Test{
	public static void main(String[] args){
		String content = "var data4 = eval('('+'[{\"device\":[\"28.0\",\"72.0\"]}]'+')');";
		String regex = "\"(\\d+(\\.\\d)?)\"";
		Pattern pattern = Pattern.compile(regex);
		Matcher matcher = pattern.matcher(content);
		while(matcher.find()){
			System.out.println(matcher.group(1));
		}
	}
