[Resolved] regular expression?

[mrhappiness]

need some help with recursive patterns here

i have

$test='<tr><td>1.1</td><td>1.2</td><td>1.3</td><td>1.4</td></tr>
<tr><td>2.1</td><td>2.2</td><td>2.3</td><td>2.4</td></tr>';

i need a regex that gives

Array
(
    [0] => Array
        (
            [0] => 1.1
            [1] => 1.2
            [2] => 1.3
            [3] => 1.4
        )

[1] => Array
    (
        [0] => 2.1
        [1] => 2.2
        [2] => 2.3
        [3] => 2.4
    )

)

if i use

%<td> ( (?>[^(<td>|</td>)]+) | (?R) )* </td>%x

i get

Array
(
    [0] => 1.1
    [1] => 1.2
    [2] => 1.3
    [3] => 1.4
    [4] => 2.1
    [5] => 2.2
    [6] => 2.3
    [7] => 2.4
)

how to integrate the <tr>?
i couldn't get two nested recursive patterns to work 🙁

with out using regex

  <?php
$test='<tr><td>1.1</td><td>1.2</td><td>1.3</td><td>1.4</td></tr> 
<tr><td>2.1</td><td>2.2</td><td>2.3</td><td>2.4</td></tr>';
$rows=explode("</tr>",$test);
foreach($rows as $key => $row)
	{
	$cells=explode("</td>",$row);
	foreach($cells as $cell)
		{
		$bits=explode("<td>",$cell);
		if(isset($bits[1]))
			{
			$array[$key][]=$bits[1];
			}
		}
	}
print_r($array);
?>

thanks, i now that will work and i don't need to use the inner foreach beaucse of the regular expression i already have

but i want to do it with 1 single line of code in my script and i think i can't get php to give me a threedimensional array with php_match_all

[sidney]

i would like to say that ther are overheads calling the regexp engine and explode is nano seconds faster

and yes you could still do it withregexp and still get a multi dimensional array

you're right and i think i'm gonna use it (at least combined with my regexp) but i'm eager to know how to do it with regexp only 🙂

i would use preg_match_callback and match th <tr></tr> and with the call to function match the <td></td>

[mrhappiness]

won't work, the callback function needs to return a string not an array

i use forach with the tr and my regexp for the td since i'm that proud of me because i got at least this to work 😉

thanks for help

[sidney]

sorry was getting preg_replace_callback confused

try this

 $test='<tr><td>1.1</td><td>1.2</td><td>1.3</td><td>1.4</td></tr> 
<tr><td>2.1</td><td>2.2</td><td>2.3</td><td>2.4</td></tr>';
preg_match_all("/<tr>(.*?)<\/tr>/",$test,$matches);
foreach($matches[1] as $key =>$val)
	{
	preg_match_all("/<td>(.*?)<\/td>/",$val,$match);
	foreach($match[1] as $cell)
		{
		$array[$key][]=$cell;
		}
	}
print_r($array);
