Question

I need to loop through all the matches in say the following string:

<a href='/Product/Show/{ProductRowID}'>{ProductName}</a>

I am looking to capture the values in the {} including them, so I want {ProductRowID} and {ProductName}

Here is my code so far:

Dim r As Regex = New Regex('{\w*}', RegexOptions.IgnoreCase) Dim m As Match = r.Match('<a href='/Product/Show/{ProductRowID}'>{ProductName}</a>') 

Is my RegEx pattern correct? How do I loop through the matched values? I feel like this should be super easy but I have been stumped on this this morning!

Answer 1

Your Pattern is missing a small detail:

\{\w*?\} 

Curly braces must be escaped, and you want the non-greedy star, or your first (and only) match will be this: '{ProductRowID}'>{ProductName}'.

Dim r As Regex = New Regex('\{\w*?\}') Dim input As String = '<a href='/Product/Show/{ProductRowID}'>{ProductName}</a>' Dim mc As MatchCollection = Regex.Matches(input, r) For Each m As Match In mc   MsgBox.Show(m.ToString()) Next m 

RegexOptions.IgnoreCase is not needed, because this particular regex is not case sensitive anyway.
