Regex search & replace to apply style to alternating TR rows

The following regular expression search & replace function will apply an alternating class to every other TR row... e.g. it will turn this:

into this:


Here's the search & replace function... It works in Dreamweaver MX, but it will probably work as is or with slight modification in any application which supports regular expressions (e.g. EditPad, etc.):

Find in: Selected Text
Search: Source Code
Find: (<tr)([^>]*>[\S\s]*?</tr>[\S\s]*?<tr)([^>]*>[\S\s]*?</tr>)
Replace: $1 class="odd"$2 class="even"$3
Dreamweaver search options: Only 'Regular Expressions' should be checked


Figuring out a way to do this has saved me lots of time, so I just figured I'd pass it on.
