Let's suppose exist a site with the following directories (subdomain)

index.php
|-sub1
   |-index.php
   |-sub1sub1
     |-index.php
     |-other.php
     |-sub1sub1sub1
|-sub2
   |-index.php
   |- ….
|-sub3
   |- ...

My question is:
1) how can I display properly locally the site of the sub1 subdomain (http://domain/sub1)
2) how can I get just the files and directory which are childs of sub1 (sub1sub1 and sub1sub1sub1 for example)

I tried the following options (for wget) but it retrieves also the files and directories which are in sub2, sub3 etc..

wget -E -H -k -K -r http://domain/sub1/index.php
