I've made right now a small aspx page that validates your regular expressions against the test data.
Also it shows all the groups, captures and matches.
Also there is a drop-down list width pre-defined regular expressiones (you can add more if you need).
I'm not very good with regular expressions, so I'm not sure that groups&captures work the way they have too. So, if u have some time - try testing my code.
Id you want I can migrate this code from web forms to windows forms or even make an Add In for VS.
P.S. If there are no groups to show - only the matched strings are shown.
To see the groups, try this:
RE - (\w+)\s+(car)
Test Data - One car red car blue car
Here is the code:
[code]
<%@ Page Language="VB" %>
<script runat="server">
Sub Button1_Click(sender As Object, e As EventArgs)
dim strRExp
dim strIn
strRExp = rExp.text
strIn = toCheck.text
Dim r As Regex = new Regex(strRExp, RegexOptions.IgnoreCase)
Dim m As Match = r.Match(strIn)
Dim matchcount as Integer = 0
Dim i As Integer
Dim j As Integer
Dim g as Group
Dim cc As CaptureCollection
Dim gc As GroupCollection
Dim c As Capture
If m.Success then
mCount.Visible = true
matchCountLabel.Visible = true
vR.text = ""
While (m.Success)
matchCount += 1
vR.text += m.value & "<BR>"
gc = m.Groups
If gc.Count - 1 > 0 then
For i = 1 to gc.Count-1
g = m.Groups(i)
If not g.ToString() = "" then
vR.text += " Group " & i & " = '" & g.ToString() & "'<BR>"
cc = g.Captures
For j = 0 to cc.Count - 1
c = cc(j)
vR.text += " Capture " & j & " = '" & c.ToString() _
& "', Position=" & c.Index & "<BR>"
Next j
End If
Next i
End If
m = m.NextMatch()
End While
mCount.text = matchCount
Else
vR.text = "No Match"
mCount.Visible = false
matchCountLabel.Visible = false
End If
End Sub
Sub REtemplate_SelectedIndexChanged(sender As Object, e As EventArgs)
dim myValue
myValue = REtemplate.SelectedIndex
if myValue <> 0 then
rExp.text = REtemplate.Items(myValue).value
Else
rExp.text = ""
End If
End Sub
