How to remove a part of a text.

I have the folling text:

-----------------------------------
</TR>
<TR>
<TD ALIGN="CENTER" COLSPAN="3">
<br><br>
<!-- ads begin -->
<center>
bla bla bla bla
<!-- ads end -->
</td>
</tr>
</table>
</body>
</html>

--------------------------------------

This is stored in $list.

I want to remove to text from <!-- ads begin -->
till <!-- ads end -->
Incl. <!-- ads begin --> and <!-- ads end -->.

The second regext works perfectly

$list =~ s/<\!\-\- ads begin \-\->.*?<\!\-\- ads end \-\->//gis;

the difference is "s" modifier - it make . to match new line symbols.
