Reading From A Website

Reading From A Website

I am a high school student who is interested in programming. I have been
working on a project to get the homework from my school's website however
I cannot seem to understand how! I first thought of using OCR programs to
read the text from the website however that proved too difficult. Then I
tried reading the webpage's content however that just gave me the source
code and the content I was looking for is not present there. Now, using
Chrome's Inspector Tool, I am able to see the Network traffic going on. I
can even get a preview of what is sent as a response from the server! That
response is what I am looking for however I do not know how to go about
getting that response! I am hoping that there is a way to read the
response of a server. I also trust that this community would not exploit
the website I provide. I am hoping to gain much experience from writing
this program. Thanks to all who can help!
