How to “Log In” to a website through a program and retrieve personal information from it

Question

Lets say I want to go into my LinkedIn account and pull out the summary about myself:

I'd...

1) Give the program the credentials to my account,

2) Have the program "log in" to the website

3) Go to my profile page

4) Look for keywords in the page to pull out my summary.

Which programming language should I use and where could I learn how to do this?

All help is much appreciated.

Answer 1

Use any web-capable language, such as Python/Ruby/Perl.

See the API Docs.
