Convert Sed command to perl command

Hello,
Can any perl experts help me convert my sed string to perl. I am unsuccessful with this.

I have to remove this string from html files OAS_AD('Top');

I have come up with this. However the requirement is in perl.

for find in $(find . -type f -name "file1.html") ; do cat $find | sed "s/OAS_AD('Top');//g"; done

Regards,

O yeah,

RHEL5 / BASH

And there are many files in the directory.

for find in $(find . -type f -name "file1.html" ) ; do cat $find | perl -npe "s/OAS_AD\('Top'\);//g"; done

google perl one liners
i saw such code
