What data structure is currently being used to represent your graph? Is it defined by edges, defined by vertices, is it a object drawn on the screen whose data can be extracted using get(), or is it an image you have to interpret to determine the vertices and connections?

GML as in Geography Markup Language? If so then looking around a little, I do not find any direct way to read such files in MATLAB. I do, though, find a Java package for dealing with them, that you should be able to use from MATLAB; see http://gcmd.nasa.gov/records/GML4J.html

Not usefully until we have a good handle on the data format. A lot of graphs come defined in terms of adjacency matrices so possibly once the data is read in, there would be no operation needed.
