Comparing contents of structures

A little background info: in a Matlab GUI, I load the files from a directory into a listbox. I have a structure with 8 possible file names and the "display name" that each filename maps to. This display name is what is populated in the listbox.
label{1,1}=file1.csv
label{1,2}=Display 1
label{2,1}=file2.csv
label{2,2}=Display 2
With the following code, I am trying to determine which files are selected, determine the actual file name, and load the files into an originally empty data structure.
data{1,8}={};
for i=1:length(index_selected)
for j=1:8 %8 possible files
if strcmp(handles.list_names{index_selected(i)},labels{j,2})==1
if isempty(data{j})==1
fid=fopen(labels{j,1});
data{j}=textscan(fid,'%s%s%u%f%f%f%f%u','Delimiter',',',...
'HeaderLines',1);
fclose(fid);
end
end
end
end
I know strcmp isn't going to work as I have it, but it illustrated what I'm going for. The main thing I am struggling with is how to get a string of the display name of a selected index.

Not sure that I fully understand (it's late), but note that strcmp() and strcmpi() do work on cell arrays. I illustrate that with a basic example:
NL = {'file1.csv', 'Label 1'; ... % Names and labels
'file2.csv', 'Label 2'; ...
'file3.csv', 'Label 3'} ;
selected = {'Label 1', 'Label 3'} ;
for ii = 1 : numel(selected)
match = strcmp(selected{ii}, NL(:,2)) ;
fprintf( 'Filename for "%s": %s.\n', selected{ii}, NL{match,1}) ;
end
Cheers,
Cedric
