around this issue replace can take a function:
var fraction;
var street_address = "1234 1/2 Old Town Alexandria".replace(/^\d*\s+(1[/]\d)\s+/i, function (match, capture) {
    fraction = capture.trim();
    return match.replace(capture,'')
});

fraction; // 1/2
street_address; // 1234 Old Town Alexndria

PHP regular expressions to extract a nested expression first then the outer expression

I wish this help you Yes, since .* matches everything (including the tags), you're matching too much. If you restrict your regex not to match across tag boundaries by preventing it from matching angle brackets, you get the desired result:
$test ='<number>1<number>2</number>3</number>';

$i=0;
$find[$i]="%<number>([^<>]*)</number>%is";
$replace[$i]="5";

$i++;
$find[$i]="%<number>([^<>]*)</number>%is";
$replace[$i]="$1";

it should still fix some issue You can use array_filter to strip out the entries in your array that start with DHL, using the regex ^DHL to see if the entry starts with DHL:
$array = array(
0 => 'DHL - 4857998880',
1 => 'DHL - 4858005666',
2 => 'COA - 485344322'
);
$array = array_filter($array, function ($v) { return !preg_match('/^DHL/', $v); });
print_r($array);
Array (
  [2] => COA - 485344322 
)
