PowerShell + WebAdministration - How to get website from webapplication?

This is how you can get the site name:

$siteName = (Get-WebApplication -name 'YourApp').GetParentElement().Attributes['name'].Value

Or even shorter:

$siteName = (Get-WebApplication -name 'YourApp').GetParentElement()['name']

I haven't dug into why, but if you use an asterisk or question mark anywhere in the string it works like a wildcard and returns as such.

I.E.

get-website -name '*myapp'   Name      ID   State    Physical Path        Bindings   ----      --   -----    -------------        --------   myapp     12   Started  C:\inetpub\wwwroot   http:*:80:  amyapp     13   Stopped  C:\anetpub\          http:*:81: aamyapp     14   Stopped  C:\another\place     http:172.198.1.2:80:host.header.com

or

get-website -name '?myapp'Name   ID State   Physical Path Bindings----   -- -----   ------------- --------amyapp 13 Stopped C:\anetpub    http:*:81:

Try this

$app = get-webapplication -name 'MyApp'foreach($a in $app){$a.Attributes[0].Value;}

This will give you all the names of the Web Applications, sometimes you can have more than 1 name for a single Web Applications.
