How to copy contents from another site, Help!!!

Hi, I'm trying to copy contents from another website. But here is my

all the contents that i copied has links that redirected to the
destination links. for example, if i click the following
link..(redirect link)

it will take me to...(destination link)

What i want to do to replace the redirect link with the destination
link when i'm copying contents from another website, without having to
manually go into each link and change it the destination links. The
reason i'm trying to do this because i dont want the source site to
know i'm copy stuff from them. Is there a way to do this? please

many thanks
