Loading xml data string instead of xml file

I want to load the xml without writing it to the filesystem.

Right now what mygrid.loadXml does is it expects a file name stored somewhere on the server.

Instead can i pass it a xml data string object.

Pls if you can respond on the forum It would be great.As this is a bit urgent.

The pro version of grid supports
    grid.loadXMLString(string_here);
