有个bug，把最后剩下的内容加入nodes之前，需要判断下长度，否则有可能加入一个空字符串

    /**
     * Split string into multiple strings
     * @param original      Original string
     * @param separator     Separator string in original string
     * @return              Splitted string array
     */
    private String[] split(String original, String separator) {
        Vector nodes = new Vector();

        // Parse nodes into vector
        int index = original.indexOf(separator);
        while (index >= 0) {
            nodes.addElement(original.substring(0, index));
            original = original.substring(index + separator.length());
            index = original.indexOf(separator);
        }
        // Get the last node
        if(original.length()>0){
            nodes.addElement(original);
        }

        // Create splitted string array
        String[] result = new String[nodes.size()];
        if (nodes.size() > 0) {
            for (int loop = 0; loop < nodes.size(); loop++) {
                result[loop] = (String) nodes.elementAt(loop);
            }
        }
        return result;
    }
