Replace string at begining of the line

Hello again people,

I have a list of websites in this format:

Code:
domain.com
domain1.com
domain2.com
domainwww.com
domain2www.com
domain3www.com
www.domain.com
www.domain2.com
www.domain3.com

I want to replace the string "www." with "nothing" but only lines that start with "www."

Thank you.
