preg_match_all没有捕获所有预期的结果

Question

I'm trying to get some info from the following source:

<random htmlcode here>
<td style="BORDER-RIGHT-STYLE:none;">
      <a id="dgWachtlijstFGI_ctl03_hlVolnaam" title="Klant wijzigen" class="wl" href="javascript: Pop(600,860,'klantwijzig','FrmKlant.aspx','?  Wijzig=true&amp;lcSchermTitel=&amp;zoekPK=+++140+12++8',false,true); ">FIRST LINE A</a>
      (SECOND LINE A)<br>
      THIRD LINE A        </td>
<random htmlcode here>
<td style="BORDER-RIGHT-STYLE:none;">
      <a id="dgWachtlijstFGI_ctl04_hlVolnaam" title="Klant wijzigen" class="wl" href="javascript: Pop(600,860,'klantwijzig','FrmKlant.aspx','?Wijzig=true&amp;lcSchermTitel=&amp;zoekPK=+++140+12++8',false,true); ">FIRST LINE B</a>
       (SECOND LINE B)<br>
      THIRD LINE B        </td>
<random htmlcode here>

What I came up with this far is the following (thanks to rubular.com)

<?php $bestand = 'input.htm';
$fd = fopen($bestand,"r");
$message = fread($fd, filesize    ($bestand));
$regexp = "FrmKlant.aspx.*\">(.*)<\/a>\s(.*)<br>\s(.*)\s\s(.*)"; 
if   (preg_match_all("#$regexp#siU", $message, $matches)) 
{   
print_r($matches);
}?

This actually seems to put the first and second line I need in a multidimensional array. So far so good, because I want a multidimensional array. However, it doesn't seem to capture the 3rd line. And somehow it creates array[4]

[1] => Array ( [0] => FIRST LINE A [1] => FIRST LINE B ) 
[2] => Array ( [0] =>  (SECOND LINE A) [1] => (SECOND LINE B) ) 
[3] => Array ( [0] => [1] => ) [4] => Array ( [0] => [1] => )

What I'm looking for is this:

[0] => Array ( [0] => FIRST LINE A [1] => FIRST LINE B ) 
[1] => Array ( [0] =>  (SECOND LINE A) [1] =>  (SECOND LINE B) ) 
[2] => Array ( [0] => THIRD LINE A [1] => THIRD LINE B ) )

Answer 1

$regexp = "FrmKlant.aspx.*\">(.*)<\/a>\s(.*)<br>\s(.*)\s\s(.*)</td>";
