RegExp find tags

I have a long  string that has tags i.e. <row> <cell> etc.

I would like to use a regexp to find all the occurences

I.E.

Dim re As New Regex("<.+>")
        Dim mc As MatchCollection = re.Matches(rtbFormattedText.Text)
        Dim m As Match
        For Each m In mc
            Console.WriteLine(m.ToString)
        Next

the problem is it returns the following line as a single match
<f name="Nobel-Regular"><z newsize="24.0"><color name="LexusGold">

How do I return each <*> using regexp?

The point I am trying to acheive is
The text is in a richtext box, when the text changes in the box, I want to go through and highlight all the tags.  Anything in <>.  I was going to use a regexp then find the position start of the match in the RTB and the length, then highlight it.  If anyone can think of a better way, I will except that as well.

Thanks
