It's easier (and faster) to do that using the API than with commands like 'ls':
import maya.OpenMaya as om
meshPath = om.MDagPath()
iter = om.MItDag(om.MItDag.kDepthFirst, om.MFn.kMesh)
while not iter.isDone():
iter.getPath(meshPath)
That will step you through every instance of every mesh in the scene
and since 'meshPath' is an MDagPath you can use its inclusiveMatrix()
and exclusiveMatrix() methods to get the full transformation matrix
for that specific instance.
If you still care about whether the mesh is instanced you can either
use iter.isInstanced() or meshPath.isInstanced()
