Parse specific data from one webpage and print to another

I have a website that has some simple data of 4 users I would like a user to view their own data without seeing the other 3 people data The data is stored on a centos 6 x64 web server, this server just serves the data, nothing else I would like you to make a search bar I can put on our other website which a user can enter the username as shown in the attached photo and it will Parse just the individual users' data and display it. Attached is the format of the data with all usernames and another screenshot of the information i want parsed after a user searches for the data via a username.
