Load variable from external TXT file

hi,
I want to be able to change an url on a trigger with an external .txt file.

like this:

getURL(“url 1 FromTXT file”);
getURL(“url 2 FromTXT file”);


In my TXT file:

url1= http://www.apple.com
url2 = http://www.microsoft.com


Result
getURL(“http://www.apple.com”);
getURL(“http://www.microsoft.com”);

Some one know if I can do that and how?

Thank you
Stephane
