You can parse XML files using the browser's integrated XML parser, see
. However, due to security reasons you can't do this across domains
– you'll have to save the XML file to your server either manually or
via server side processing (e.g. C++, PHP or whatever programming
language your server has to offer).  also notes this. Flash can
probably work cross-domain, but I'm not sure about that and I don't
know if it's even possible to transfer the data from Flash to HTML
DOM/JS, but if you don't have server side programming support it's
probably your only chance.
Context menu: You don't. Taking control way from the user is never a
good idea and that's the reason why all modern browsers don't allow
you to do such a thing. While there may be valid use cases it was
often abused to do annoying things like popping an alert box "right
click now allowed". Since no webpage uses context menus for these
reasons, discoverability would be pure luck. Better make a webpage
behave like a webpage – makes better user experience, too. My
suggestion would be to add a similar menu like the layer switcher is
