我有一个巨大的名字列表，必须从中提取名字首字母和姓氏。请在下面找到示例名称：

T.-P。SU
H. SPRONG
G. VAN MEER
C. PERRONE CAPANO
EC PARKER-ATHILL
RJ BALICE-GORDON
DB VAZQUEZ SANROMAN
BPC CHEN
JP Bennett, Jr
T.-K. 库克-卢克亚诺夫

预期输出：

TP SU
H SPRONG
G VAN MEER
C PERRONE CAPANO
EC PARKER-ATHILL
RJ BALICE-GORDON
DB VAZQUEZ SANROMAN
BPC CHEN
JP BENNETT JR
TK KUKKO-LUKJANOV
我已经使用了拆分功能来拆分它们。我们能否有更好的正则表达式来正确解析它们。请建议。

谢谢。

以下正则表达式适用于您的示例数据：

((?:[A-Z][-. ]+)+) ([- A-Z]+(?:, \w+)?)

示例：http ://www.rubular.com/r/cM87Prp2to

第 1 组将是第一个名称，第 2 组将是第二个名称。这导致以下组，如果其中任何一个不是您所期望的，请更详细地编辑您的问题：

T.-P. SU -> (T.-P.) (SU)
H. SPRONG -> (H.) (SPRONG)
G. VAN MEER -> (G.) (VAN MEER)
C. PERRONE CAPANO -> (C.) (PERRONE CAPANO)
E. C. PARKER-ATHILL -> (E. C.) (PARKER-ATHILL)
R. J. BALICE-GORDON -> (R. J.) (BALICE-GORDON)
D. B. VAZQUEZ SANROMAN -> (D. B.) (VAZQUEZ SANROMAN)
B. P. C. CHEN -> (B. P. C.) (CHEN)
J. P. BENNETT, Jr -> (J. P.) (BENNETT, Jr)
T.-K. KUKKO-LUKJANOV -> (T.-K.) (KUKKO-LUKJANOV)

这是我的解决方案。我的目标不是提供最简单的解决方案，而是提供一种可以采用各种（有时很奇怪）名称格式的解决方案，并在名字和姓氏首字母（或在单名的情况下）单个首字母的情况下生成最佳猜测。

我还尝试以相对国际友好的方式编写它，使用 unicode 正则表达式，尽管我没有任何为多种外国名称（例如中文）生成首字母的经验，尽管它至少应该生成一些可用的东西代表人，在两个字符之下。例如，用韩语给它取一个名字，如“행운의 복숭아”，会产生 행복，正如你所预料的那样（尽管这在韩国文化中可能不是正确的做法）。
