我正在運行VBA(Excel 2003)並測試了正向lookbehind正則表達式模式。我運行下面的功能,但得到以下錯誤:正則表達式Excel Excel VBA
Run-time error '5017': Method 'Execute' of object 'IRegExp2' failed
我也試過 Set re = CreateObject("vbscrip.regexp")
,但我得到了同樣的錯誤。我已經成功測試了一些積極的lookahead,他們的工作。這只是背後的問題。我已經用Expresso測試了下面的模式,它工作的很好。這是VBA特有的味道問題嗎?
Function regexSearch(pattern As String, source As String) As String
Dim re As RegExp
Dim matches As MatchCollection
Dim match As match
'Create RegEx object
pattern = "(?<=a)b"
source = "cab"
Set re = New RegExp
re.Multiline = False
re.Global = True
re.IgnoreCase = False
re.pattern = pattern
'Execute
Set matches = re.Execute(source)
'Output
For Each match In matches
str = str & match & " "
Next match
regexSearch = str
End Function
你有沒有找到解決類似的問題?我不知道如何做這項工作。 – Yaegz
