parsing page with preg_match_all()

Hallo!

I capture web page and store info in my site. Its working good, but I have some wrong problem...

Here is a code were catch up remote url:

<?php
$url = "http://www.example.com";
$data = implode("", file($url));

// Get content items
preg_match_all ("/<div align=\"center\">([^{']*?)<\/div>/",} $data, $matches, PREG_SET_ORDER);

foreach ($matches as $val) {
echo $val[0] . "\n";

}
?>

This code get content from remote site and output it in my site.
But ..... The page look like this:

I getting all contents from <div></div> tags!!

I want get contents between middle div tags.

How can I modify code above with preg_match_all () correctly?

Thanx!
