I want to match the terms "TextCtrls" and "LabelCtrls". When I find "TextCtrls" I want to replace with "Txt" and when I find "LabelControls" I want to replace with "Lbl". Online Demo

Is this possible with DTE.Find.ReplaceWith?

DTE.Find.FindWhat = "Container\(""\w+""\)\.(?:TextCtrls|LabelCtrls)\(""(?<ControlName>\w+)""\).Text"

DTE.Find.ReplaceWith = "<psydocode:Txt|Lbl>${ControlName}.Text"

Solution 1: Reusing the text present in input string

Since the text you want to replace with actually is present in the source text, you may (ab)?use the capturing groups here the following way:

DTE.Find.FindWhat = "Container\(""\w+""\)\.(?:(?<f>T)e(?<s>xt)Ctrls|(?<f>L)a(?<s>b)e(?<t>l)Ctrls)\(""(?<ControlName>\w+)""\).Text"
DTE.Find.ReplaceWith = "${f}${s}${t}NameOfControl.Text"

See the .NET regex demo

Groups f, s and t are filled with the necessary bits of text and only have text if the corresponding alternatives match.

Solution 2: Using MatchEvaluator for custom replacement logic

You may use MatchEvaluator to check what group matched or what group value is and then implement your own replacement logic:

Dim s As String = "Container(""Name1"").TextCtrls(""Name2"").Text" & vbCrLf & "Container(""Name1"").LabelCtrls(""Name2"").Text"
Dim pattern As String = "Container\(""\w+""\)\.(?<test>TextCtrls|LabelCtrls)\(""(?<ControlName>\w+)""\).Text"
Dim result = Regex.Replace(s, pattern, New MatchEvaluator(Function(m As Match)
        If m.Groups("test").Value = "TextCtrls" Then
            Return "TxtNameOfControl.Text"
        Else
            Return "LblNameOfControl.Text"
        End If
    End Function))

Output:

  • Thank you Wiktor. Do you know a solution if the letters are not in the original string? Is it possible? Please don't invest too much time, but maybe you know it.... – Jürgen Scheffler Nov 06 '18 at 15:21

    @JürgenScheffler If you have access to actual .NET code, yes, it is easy with `MatchEvaluator`. – Wiktor Stribiżew Nov 06 '18 at 15:34
  • nice hint, sure I got .net code available because I am using it via Visual Commander Extension, well I dont have intellisense there but I will find out, thx. – Jürgen Scheffler Nov 08 '18 at 15:25
