Help with a Bash script

I'm quite new to Bash scripting, and just need a little pointer on how
to go through a file, and execute commands there in until the end of the
file is reached.

The idea is this, a list of iptables rules is downloaded, they are run
through a set of commands to get the file in a state ready to run. I
need to read each line of that file, and execute each one. I'm not sure
on loops in bash, and hope someone can help... :)

I download this file:
http://www.okean.com/antispam/iptables/rc.firewall.china

Then run it through this to sanitize it
sed 's/--dport 25//g' rc.firewall.china|cat|grep "^[ ]*iptables" >
rc.firewall.china_mod

Now, how do I loop through that file executing each line in a for while
loop?
