excel 利用正则表达式匹配工作表中的数据

excel 利用正则表达式匹配工作表中的数据

sheet1中A列放需要匹配的数据

sheet2中A列放正则表达式，可以是多个，但至少一个

匹配到了则在sheet1中C列对应行显示相关标记内容，比如本案例中显示1111

Sub Test()
atr = Worksheets("Sheet1").Range("a65536").End(xlUp).Row
btr = Worksheets("Sheet2").Range("a65536").End(xlUp).Row

a = Worksheets("Sheet1").Range("a1:a" & atr).Value
b = Worksheets("Sheet2").Range("a1:a" & btr).Value

ReDim c(1 To atr, 1 To 1)
Set reg = CreateObject("vbscript.regexp")
With reg
.Global = True
.IgnoreCase = True
For ar = 1 To atr
For br = 1 To btr
If btr = 1 Then
.Pattern = b
Else
.Pattern = b(br, 1)
End If
If .Test(a(ar, 1)) Then
c(ar, 1) = "1111"
Exit For
End If
Next
Next
End With
Range("c1:c" & atr) = c
Set reg = Nothing
End Sub
