Web scraping

I am working on a project which enables user to access Web pages using SMS without data or WiFi, I have to create a backend which process users SMS and then extract the requested Web page source code for only text,eliminating images and css.I have done with android front end using android studio.The backend development has become hassle now since I am complete newbie to this.I have found numerous article on this topic using node.js but unable to do that, consider this scenario :
When a user enters a webpage address in my android client app, it sends user Web address as SMS through telerivet service to my telerivet control panel. I need to have a simple Java script or any other scripts that scraps the webpage which user has requested via the SMS.

NOTE:the page needed to scrap is the page user has requested via SMS

Please help, since this is for my final year project..
