I want to find content inside of a DIV. I just want to specify the DIV’s id; the rest is automatically adjusted under preg_match.
E.g.:
<div id="midbuttonarea" etc...>some text...</div>

Is there something which prevents you from using phps DOM-classes? It would make things a lot easier.Yoshi– Yoshi2011-04-29 07:17:54 +00:00Commented Apr 29, 2011 at 7:17

Brenton is right. Anyway, here you have:
<?php
function findDivInnerHtml($html, $id){
preg_match("/<div .* id=\"{$id}\" .*>(.*)<\\/div>/i", $html, $matches);
return $matches[1];
}
?>
Sample usage:
<?php
$html = '<div id="other"> xxx </div> <div id="midbuttonarea" etc...>some text...</div> ';
$innerHTML = findDivInnerHtml($html, 'midbuttonarea');
echo $innerHTML; //outputs "some text..."
?>
Hope this helps.

Forgot to tell you that
$html doesn't have to have line breaks. You can easily remove them with str_replace firstYou're much more likely to get a good result using an HTML parser to parse HTML instead of Regex. It's extremely difficult to parse HTML with Regex, and the result may not be very reliable.
Check the accepted answer to this question: How do you parse and process HTML/XML in PHP? for some suggestions on how to go about it.

it can be possible in php regular expression.
