Read a html file, extract email addresses?

[Duke of Hazard]

I have searched without success for a simple script that can read any
text html file and extract the email addresses from it. I am not
interested in spamming people. I play a sport that requires me to
email people when I travel to find partners. Unfortunately only 20%
are able to reply because their schedules don't mesh with mine. So
this script would be a great way to email 5-10 people from a certain
website without having to copy/paste each address directly.

Thanks,
