Hi all.
I am almost a beginner in matlab GUI's. My task is quiet simple: I have to create a GUI with a pushbutton that allows you to open a XML file. But the file should be opened using XMLfox (an XML editor) so that you can edit the file easily. The code I wrote is:

[filename, pathname] = uigetfile('*.xml', 'Pick a namelist');
if isequal(filename,0) || isequal(pathname,0)
disp('User pressed cancel')
system('C:\Programmi\RustemSoft\XMLFox\xmlfox.exe (filename)')

It just opens the software XMLfox, but not the file I picked!
Any help would be appreciated. Thanks!!!
