I read XML file using GUI pushbutton, extract some data, and do some manipulations for them. The thing is although I save the required variables to workspace (using assignin), I can't use them outside the pushbutton callback function for further manipulation because matlab tells me 'undefined variables'! any suggestions? Thanks

You need to make sure you click 'Attach File' after clicking the paper clip and choosing your file. A lot of people (including myself sometimes) miss that and think it is attached just through choosing the file under the paperclip.

Did you also define the workspace location?
e.g.
assignin('base','your_variable_name',your_variable_value);

Yes this what I meant; using it in another callback. It works now, thanks a lot.

If you just want to share data between callbacks then you shouldn't go through the base workspace at all, but I guess it works for you for now.
