Subject: Ruby multiline regex problem

Code:

"<td align="left" ><div style="width: 165px; height: 175px;"><a
href="http://www.amazon.com/Rails-Recipes/dp/0977616606/ref=pd_sim_b_njs_img_1">testPit
something here Best</td>"


Pattern:

<td.*?>.*?<\/td\s*>


I'm trying to match this whole block and use it for further parsing.
This started from an example in Brian Merick's book "Everyday
Scripting..." that had to be modified because amazon has changed their
presentation to tables instead of lists.

Anyway, the regex works fine as a single-line. as soon as I introduce
this:

"<td align="left" ><div style="width: 165px; height: 175px;"><a
href="http://www.amazon.com/Rails-Recipes/dp/0977616606/ref=pd_sim_b_njs_img_1">testPit
something here

Best</td>"

it fails.

When I try this same expression with perl using the //s mode, it works.
I understand Ruby uses //m (multi-line mode in nearly the same fashion
causing newlines to be considered any character, so it should work,
right? Can anyone tell me what I am doing wrong here? Why isn't
"multiline" mode working?

Thanks!
