Regex.Replace match with stuff + match?

[crptcblade]

I'm looking in a string for anything that starts with "${" and ends with "}", and then replace it with "<b>whatever the match was</b>".

Is this possible? Whoever's answer I like best gets Marty's job for a week.

Nobody can even tell me to shut the hell up? I've lost all faith in you people.

Before you get regex gung ho, try something like this:

Dim yourstring As String = "${Wild Bill}"
        yourstring = yourstring.Replace("${", "<b>${")
        yourstring = yourstring.Replace("}", "}<\b>")

        yourstring = yourstring.Replace("${", "<b>${")
        yourstring = yourstring.Replace("}", "}<\b>")

Well, what if there is a "${" without a matching "}", or vice versa, which is a distinct possibility with what I'm doing...

It will definately be tricky, do you have a sample of the text you wish to parse?

Something like this ought to do it:

Dim inputString As String = "This ${is a test.}  It hopefully ${does the job}"
        Dim regexString As String = "(\$\{).+(\})"
        Dim regexMatch As String = ""
 
        Do
            regexMatch = Regex.Match(inputString, regexString).Value
            If Not inputString.Equals("") Then inputString = inputString.SubString(2, inputString.Length - 3)
        Loop While Not regexMatch.Equals("")
 
        MessageBox.Show(inputString)

I think there is a way to get all the matches in one go using the "Matches" class, but this works just as well; you'd have to loop through all the matches anyway.

Dim inputString As String = "This ${is a {test}.}  Random header ${. It hopefully ${does the job}"
        Dim Headers() As String = Regex.Split(inputString, "\$\{")
        Dim outputstring As String
        For Each mt As String In Headers
            Dim i As Int32 = mt.LastIndexOf("}"c)
            If i > 0 Then
                outputstring = outputstring.Insert(outputstring.Length - 2, "<b>")
                outputstring &= mt.Insert(i + 1, "</b>")
            Else
                outputstring &= mt
            End If
            outputstring &= "${"
        Next
 
        MessageBox.Show(outputstring.Substring(0, outputstring.Length - 2))
