将正则表达式更改为:

(.*?)\s(\d{5})\s(.+?)\s?(FINLAND|SUOMI)?$

让第三个组没有贪心会让您匹配可选的空格+国家(地区)选择.如果第4组不匹配，我认为它将是未初始化的，而不是空白，这取决于语言.

Making group three none greedy will let you match the optional space + country choices. If group 4 doesn't match I think it will be uninitialized rather than blank, that depends on language.
