Create a struct inside a cell array
显示 更早的评论
I'm using struct2xml from FileExhange and it's quite picky on the format of the structure to export. Basically I loose information when exporting data arrays (they are converted to strings). Example;
x = 1:3;
s.child.Text = x;
xml = struct2xml(s)
xml =
<?xml version="1.0" encoding="utf-8"?>
1 2 3
As you can see, the array of doubles has been converted into a string which makes it cumbersome for me to read the data back. I would like to have a format of;
<?xml version="1.0" encoding="utf-8"?>
1
2
3
but here's my pickle. In order for that to happen, I have to have a cell array of child-objects with a struct('Text', Value) in each.
s.child.Text = num2cell(x);
won't work, as struct2xml ultimately expects a struct (with field Text) but only gets a cell.
s.child = struct('Text', num2cell(x));
won't work, as that generates three separate structs. Multiple structs must be in cells.
cellfun(@struct, 'Text', num2cell(x));
won't accept the field name 'Text' unfortunately.
Any brilliant ideas?

I do not know struct2xml, but the author does. Did you try to contact him already?
Intuitively I'd try:
s.child(1).Text = 1;
s.child(2).Text = 2;
s.child(3).Text = 3;

s.child = cell(1, length(x)); % Pre-allocate
for i = 1:length(x)
s.child{i}.Text = x(i);
end
Is this "nicer"?
