Instead of calling the function, reference your function as an element in an associative array by name:

var funcName = // parse your xml for function name
var params = new Array();
params[0] = 10.2; // from your parsed xml
params[1] = 'some text'; // also from your parsed xml

// functions are attached to some Object o:

o[funcName](params); // equivalent to o.funcName(params);
