Buid a web page for a responsive xml and text file reader.

The page require the user inform a given xml file where the size may vary from 1mb to 6gb. when its submited to the server the server must recognize that given xml, parse and sent it back to a web interface in a grid format. Its a very important requirement performance and memory managent. What I see for a possible solution is to use html 5 file upload and send it in chunks to the server, the server start receiving the data, discover the file schema, transform it in a object and sent it back to the page display in a data grid to be manipulated by the user. I believe once its done for a given schema it would be adapted for others. Its only expected the user inform a given xml without inform anything else. The logic for parse and response must be safe in the server side. The xml files are usually based on complex schemas.
