I have a little script in Perl, HTTP POST request

```
my $request =  $ua->post( $url, [ 'country' => 10, 'evalprice' => 0 ] );
my $response = $request->content;

```

Now I know that in the response there will be this part, which appears only once

```
:&nbsp;<b>9570&nbsp;USD

```

I want to take only the number 9570 (or whatever it will be), I don't know how to search for

```
:&nbsp;<b>

```

and then just take the part after that and before

```
&nbsp;USD

```

I guess regular expressions will help, but I can't figure out how to use them here.
