Hello,

if I use:

DOMnode = readxml(my_file_name_source);
writexml(DOMnode , my_file_name_target);

I'll get the same XML file with the addition of:

<?xml version="1.0" encoding="utf-8"?>

How can I create my new file without that auto generated line?

THANKS

You could do something like this, which first writes the xml file as usual (with the first line) using xmlwrite(), then reads the file into a variable, removes the first line, and writes the rest back to the same file.

DOMnode = xmlread(my_file_name_source);
xmlwrite(DOMnode , my_file_name_target);
% read the xml file
fid = fopen(my_file_name_target,'r');
data = fread(fid);
fclose(fid);
% remove the first line
idx = find(data == newline(),1);
if ~isempty(idx)
    data(1:idx) = [];
end
% write the remaining contents back to the same file
fid = fopen(my_file_name_target,'w');
fwrite(fid,data);
fclose(fid);
