一个分段从字符串中提取金额的正则

        String str = "asd2312.3fasf-0.114fa+234.3sdf";

        //String regxp = "[^(-)?(([1-9]{1}\\d*)|([0]{1}))(\\.(\\d){1,2})?]";
        String regxp = "((-)?(([1-9]{1}\\d*)|([0]{1}))(\\.(\\d){1,2})?)";


        Pattern p = Pattern.compile(regxp);
        Matcher m = p.matcher(str);
        while (m.find()) {
            String pStr = m.group();
            System.out.println(pStr);
        }
