[PHP] Re: Regular Expression ? from newbie

[_lallous]

here's your PHP code,

<?
$mem = '
<table cellspacing="2" cellpadding="2" border="1">
<tr>
    <td align=center>banana</td>
    <td align=left>.46</td>
    <td align=right>.55</td>
</tr>

<tr>
    <td align=center>pear</td>
    <td align=left>.38</td>
    <td align=right>.51</td>
</tr>

<tr>
    <td align=center>apple</td>
    <td align=left>.59</td>
    <td align=right>.33</td>
</tr>
</table>';

$re2 =
"/.*?<tr[^>]*>.*?<td[^>]*>(.+?)<\/td>.*?<td[^>]*>(.+?)<\/td>.*?<td[^>]*>(.+?
)<\/td>.*?<\/tr>/is";
$re1 = '/<table cellspacing="2" cellpadding="2"
border="1">(.+?)<\/table>/is';

if (preg_match($re1, $mem, $matches))
{
  if (preg_match_all($re2, $matches[1], $tddata, PREG_SET_ORDER))
  {
    for ($i=0;$i<count($tddata[0])-1;$i++)
    {
      echo "name={$tddata[$i][1]} p1={$tddata[$i][2]}
p3={$tddata[$i][3]}\n";
    }
  }
}
?>
