--[[
    获取当前参数的序号，支持多个序号，且支持多种写法兼容。
pattern:
    格式以正则表达式为基础，另增以下匹配符：
    % - 将自动替换成正则表达式的“(%d+)”，用以匹配这个位置上的序号。
    %% - 将自动替换成正则表达式的“%”，用作正则表达式中“%”字符的转义。
返回：
    【所有序号文本】     【所有序号数值】
    注：以上每个值段都是一个独立的返回值列表项；
示例：
    paramname: prefix000infix10postfix08
    pattern: ^prefix%infix%postfix%$
    返回：000     10     08     0     10     8
