The runtime map does not contain any position information.
The position and scale is only maintained on the client.
Each request for a map image contains the center coordinates and a scale.
Given this, there cannot exist a server side API for doing this.
The runtime map is not in Xml format, but binary.
The MapDefinition is in Xml format, and you may alter it as such.
It will not change the position of any visible map, but rather alter the
initial map view when displaying a new map.

I wanted to ask about the process which you have to go through in order to
use the MapGuide server side API to move the map position and zoom.
The simple functionality seems to exist on the client side via the
JavaScript libraries to move the map to a given x, y, position via just a
just a function call. Inspite of my digging around though I can't find any
such functionality for the Server side API though I might not be looking in
the right place.
It has been suggested that it might require loading, modifying and saving
XML definitions to achieve this (though this seems like a complicated way of
doing things). Does anyone have an example of moving / zooming the map from
the Server API?
I would not have thought it would be rocket science. For larger, more
intricate and complex mapping systems such as the one we are working on it
would be expected the bulk of the business logic would exist on the server
in the form of libraries there and so doing as much as possible on the
server is desirable. A the end of the day the JavaScript function
"ZoomToView" I would expect must call something on the server.
