Since you dont provide what kind of data structure the urls are stored in, I assume it's a raw string:

$data_raw = "http://exmpale.com/abc/exmpale.html
http://exmpale.com/abc/exmpale1.html
http://exmpale.com/abc/exmpale2.html
http://exmpale.com/abc/exmpale/exmpale1.html
http://exmpale.com/abc/exmpale/exmpale2.html
http://exmpale.com/abc/exmpale/exmpale3.html
http://exmpale.com/abcd/exmpale1.html
http://exmpale.com/abcd/exmpale2.html
http://exmpale.com/abcd/exmpale2.html
http://exmpale.com/abcd/exmpale4.html
http://exmpale.com/abc/abc/exmpale1.html
http://exmpale.com/abc/abc/exmpale2.html
http://exmpale.com/abc/abc/exmpale3.html
http://exmpale.com/abc/abc/exmpale4.html
http://exmpale.com/abc/abc/exmpale5.html";

$urls = explode("\n", $data_raw);

$accept_host = "exmpale.com";
$accept_path = "/abc/";

$filtered_urls = array_filter($urls, function($url) use($accept_host, $accept_path) {
    $parts = parse_url($url);   
    return $parts['host'] == $accept_host
        && strpos($parts['path'], $accept_path) === 0
        && strpos($parts['path'], '/', strlen($accept_path)) === false;
});

printf("<pre>%s</pre>", print_r($filtered_urls, true));

Yields:

Array
(
    [0] => http://exmpale.com/abc/exmpale.html
    [1] => http://exmpale.com/abc/exmpale1.html
    [2] => http://exmpale.com/abc/exmpale2.html
)

Simply use the php function preg_match_all and the matched string will get loaded in an array that you supply to the above function as an argument. Please read the PHP manual on preg_match_all and create a regex for your needs. You can test your regex here
