Hi Naimish and welcome to our forum!
I'm guessing that the XMLFormView control (what's this?) is expecting it to be cached locally on the machine. Try opening the XSN from the published site by either clicking on the XSN or an XML file (by the way, the SharePoint document library is not for Form documents - use the Form Library to publish to SharePoint). Once you cache it, I'm guessing that the XMLFormView may work but it's just a guess.
