How to extract information from h5disp?

Could someone please, advise as to how to extract information in the form of string from the h5disp? Intuitively, I was trying a=h5disp('Fe3cell1_01.h5','Aligned/data/Size') but with poor luck...

Thank you.

What data are you trying to extract?

h5info will return the same content as the disp, but in the form of a structure. While h5read can specific data from the file.
