Regular expression help needed

[b007uk@gmail.com]

Hi everyone,
Could someone please help me with this regular expression,
this is the string:

<top cellpadding=2 ><tr><td valign=top><b>D VD</bduel:
<b>High</b>-<b>definition </bshowdown<br><f ont size=-1><font
color=6f6f6f>TM Cn vxcv etrwerwerwer <brsdfsd <bdfasdasd <br>
asdasda

I need to match everything from <td valign=topto the first <br>, like
this:
<td valign=top><b>D VD</bduel: <b>High</b>-<b>definition </b>
showdown<br>

These are the expressions i tried:

<td valign=top>.*<b r>
<td valign=top>.*<b r>{0,1}
<td valign=top>.*<b r>{1,1}

They all match everything untill the LAST break, and i only need first
occurrence of break <br>
:(
Thank you very much!

Searching in this group would have revealed the answer, others and I have
said it numerous times the last 2 weeks:

Make your * ungreedy by placing a questionmark beside it:
<td valign=top>.*?< br>

I would have made it:
'|<td[^>]*valign=top[^>]*>(.*?)<br|si'

Advantages:
1. Now the "valign=top " is cheched, but the td tag may get other attributes
in the future, which will now be no problem.
2. I've left the last of <brout, to comply with the possibilities of
<br>, <br/& <br />.
3. Parenthasis around the actual content you like to to get/match, so it can
be referred to later without extra code.
