regex - VBA 正则表达式和组

Question

在以下电子邮件正文中应用以下正则表达式:

(pls[a-zA-Z0-9 .*-]*) \(([A-Z 0-9]*)\)

电子邮件正文:

pls18244a.lam64*fra-pth (PI000581) 
pls18856a.10ge*fra-pth (PI0005AW) 
pls25040a.10ge*fra-pth (IIE0004WK) 
pls27477a.10ge*fra-pth (WL050814) 
pls22099a.stm4*par-pth (PI0005TE)

返回 5 个匹配，有两个组。使用增量变量复制excel行中的每个匹配组在每个匹配中获取组的VBA脚本是什么？

Answer 1

不对您的正则表达式模式进行任何更改。使用以下方式，您可以遍历每个匹配的组:

str="pls18244a.lam64*fra-pth (PI000581)pls18856a.10ge*fra-pth (PI0005AW)pls25040a.10ge*fra-pth (IIE0004WK)pls27477a.10ge*fra-pth (WL050814)pls22099a.stm4*par-pth (PI0005TE)"
Set objReg = New RegExp
objReg.IgnoreCase=False
objReg.Global=True
objReg.Pattern = "(pls[a-zA-Z0-9 .*-]*) \(([A-Z 0-9]*)\)"
Set objMatches = objReg.Execute(str)
For Each match In objMatches             'The variable match will contain the full match
    a= match.Submatches.Count            'total number of groups in the full match  
    For i=0 To a-1
        MsgBox match.Submatches.Item(i)  'display each group
    Next
Next
Set objReg = Nothing
