xmllint: Remove <?xml version="1.0"?>

Question

I am using xmllint to clean up my .xml file but for some reason the output adds <?xml version="1.0"?> to the first line. Is there a flag to have this be removed?

Answer 1

Both of the following seem to avoid insertion of <?xml version="1.0"?>:

• xmllint --exc-c14n data.xml

• xmllint --c14n data.xml

Hint:

xmllint --help

-or-

man xmllint
