Return the output (which is a structure) of an eval function

Hi,

i am using the eval function to create a structure from the data i have like shown below:

c =
RoadXML.Network.Geolocalisation.Translation.Attributes.x = 123

When i pass this to eval, it returns a structure to the workspace as seen below:

eval(c)
RoadXML =  Network: [1x1 struct]

Is there any way by which i can capture this structure in a variable so that i can use it for the furthur processing of the data? Thanks in advance for the tip,

Regards,
