正则表达式从列表中提取所有组作为 arrayformula

Question

我正在寻找能够从列表中提取所有可能组的正则表达式数组公式。这是一个可视化：

到目前为止我试过：

=ArrayFormula(REGEXEXTRACT(A2:A6, "["&TEXTJOIN("|", 1, A8:A)&"]"))
=ArrayFormula(REGEXEXTRACT(A2:A6, "[("&TEXTJOIN("|", 1, A8:A)&")]"))
=ArrayFormula(REGEXEXTRACT(A2:A5, "["&TEXTJOIN("|", 1, "("&A8:A&")")&"]"))
...

Answer 1

也许只是开箱即用，但如果您在 B2:

中尝试过会怎么样

=ARRAYFORMULA(IFERROR(TRANSPOSE(FILTER(A:A,ISNUMBER(SEARCH(SUBSTITUTE(A:A," ","*"),A2)))),""))

Answer 2

你可以在 B2 中像这样伪造它：

=INDEX(IF(REGEXMATCH(A2:A5, 
 TRANSPOSE(SUBSTITUTE(A8:A10, " ", ".*"))), TRANSPOSE(A8:A10), ))
