Programming :: Automate Copy And Paste Of Files From The Internet?

Here is what I currently do and want to automate:

1) I manually enter a particular web site address in the browser.

2) When the page displays on my machine, it shows a number of links I need to visit, one after the other.

3) Each of these links display another page (file) from which I "cut and paste" information. I do this by highlighting manually the wanted info, click "copy" then select an open file on my computer, select "undo" if necessary to remove any previous content, click "paste" and then "save".

4) I then call a Yabasic program that reads the saved file and trims unwanted info.

5) At the completion of the Yabasic program, I click the web page tag, click the "back" button to return to the first page (since I am in the second) and click the next link in this first page till all links have been visited.

6) visit the next known web site and repeat 1 to 5

In an automated program, what I need to do is:

1) Visit the known page of the web site showing the links
2) save the page showing the links (the first page)
3) make a list of those links
4) visit each link one after the other and save its page from which I will programmatically (Yabasic) select info.
5) repeat 1 to 4

I can do this in "Yabasic" (which can issue Linux commands) or PHP although I do not know PHP much.the purpose of this is to associate towns and cities of the world with their respective political/geographical divisions and their respective time zone. This has to be done often because that data changes regularly.
