我想从Excel VBA中的给定字符串中提取匹配的RegExp模式.
例如,
鉴于此表达式:
"[0-9]*\+[0-9]{3}\@[0-9]*\+[0-9]{3}"
从这个字符串:
“CSDT2_EXC_6 000 @ 6 035_JM_150323”
我想得到:“6 000 @ 6 035”
但我不知道如何做到这一点.
我能得到的最近的是:
Function getStations(file_name As String) 'Use Regular Expressiosn for grabbing the input and automatically filter it Dim regEx As New RegExp With regEx .Global = True .MultiLine = True .IgnoreCase = True 'This matches the pattern: e.g. 06+900@07+230 .Pattern = "[0-9]*\+[0-9]{3}\@[0-9]*\+[0-9]{3}" End With If regEx.Test(file_name) Then strReplace = "" getStations = regEx.Replace(file_name,strReplace) Else getStations = "Hay un problema con el nombre. Por favor,arréglalo" End If End Function
但这会带给我以下内容:
“CSDT2_EXC__JM_150323”
我只想采用匹配的模式.我怎样才能做到这一点?
万分感谢所有回复;)
解决方法
你可以用这个:
Function getStations(file_name As String) 'Use Regular Expressiosn for grabbing the input and automatically filter it Dim regEx As New RegExp With regEx .Global = True .MultiLine = True .IgnoreCase = True 'This matches the pattern: e.g. 06+900@07+230 .Pattern = "[0-9]*\+[0-9]{3}\@[0-9]*\+[0-9]{3}" End With If regEx.Test(file_name) Then getStations = regEx.Execute(file_name)(0) Else getStations = "Hay un problema con el nombre. Por favor,arréglalo" End If End Function
