I have an xmlcomp.Edits object that was created when performing a comparison via the command
root = slxmlcomp.compare(...)
In this case, an xmlcomp.Edits object was created (see attached file) but all properties are empty. However, I don't know how to check if the properties are empty so I can catch the error that occurs when I try to access the properties. Is there a command to use when the object's properties are empty?

if you want a function for your check, you could implement it for your needs like this:
function ispropOut = SOME_FUNCTION(objIn,nameIn)
ispropOut = false(size(objIn));
for nObjRow = 1:size(objIn,1)
for nObjCol = 1:size(objIn,2)
try
objIn(nObjRow,nObjCol).(nameIn);
ispropOut(nObjRow,nObjCol) = true;
catch
end
end
end
end

Might this help?
>> EmptyRoot=xmlcomp.Edits('')
EmptyRoot =
Edits with no properties.
>> isequal(root,EmptyRoot)
ans =
logical
1
>> isequal(root2,EmptyRoot)
ans =
logical
0
