how format xml files using swift?

ok, solved question myself.

edit gdataxmlnode.m make pretty-print xml default

open gdataxmlnode.m, , find method - (nsstring *)xmlstring

replace: int format = 0 int format = 1;

then write code below in swift:

let document : gdataxmldocument = gdataxmldocument(rootelement: rootelement) let xmlstring : string = gdataxmldocument.prettyprintxml(nsstring(string:document.rootelement().xmlstring()) string) 

this working fine.
