Regular Expression, detecting certain words

I've got a regular expression that checks if sentences such as "A duck is a bird" or "A kitten is a cat" are valid:


I'm using vb.net and I want to tell which words are different, i.e I want to pickup from the first sentence "duck" and "bird" and "kitten" and "cat" from the second one.  How can I do this?

Also, I tried this but it didn't quite work:

        Dim test As String = "A duck is a bird"
        Dim re As New Regex("^(A)\s\w+\s(is)\s(a)\s\w+$")
        test = re.Replace(test, "$1 $2 $3 $4 $5")
        Response.Write("<br/>'" + test + "'")
