how to make output the file well-structured by adding link break

Answer 1

There is no way in doing this with the normal SimpleXML extension. You can however write yourself a method/function that pretty-prints you the XML. Have a look at the php manual, someone already made the work.

If you don't want to use that method you could also switch from SimpleXML to XMLWriter which provides a method to set the indentation (XMLWriter::setIndent)of printed XML.
