How do you format XML files like this using swift?

Answer 1

Ok, finally I solved this question by myself.

Edit GDataXMLNode.m to make it pretty-print XML by default

Open GDataXMLNode.m, and find method - (NSString *)XMLString

Replace: int format = 0 with int format = 1;

then write code like below in Swift:

let document : GDataXMLDocument = GDataXMLDocument(rootElement: rootElement)
let xmlString : String = GDataXMLDocument.prettyPrintXML(NSString(string:document.rootElement().XMLString()) as String)

This is working fine.
