What programming language to check if a website's text has changed?

What programming language would be able to write a program where it goes and checks a website's text say twice a day to see if a certain number has dropped below a certain threshold, and then notify me by text message if it has?


For example, my friend wants me to write a program to help him register for a class, but currently the class is full. He wants the program to go to this link:

Then the program should somehow click on the link "Schedule for Psych 204", opening up a little box below the link with information about how many students are in the class. Currently, clicking on the link reveals



PSYCH 204 | 3-4 units | Class # 30341 | Section 01 | Grading: Letter or Credit/No Credit | LEC | Students enrolled: 33 / 30



The program should then be able to check if the Students enrolled: 33 / 30 ever drops to 29 / 30 twice a day and send me a text message if it is.


What's an easy programming language to carry this out?
