Add compact mode to XMLPrinter, for printing without '\n' and space. 

let output file smaller.
usage:
//------------------------------------------------
XMLPrinter printer;
printer->SetCompactMode( true ); //enable compact mode
doc->Print( &printer );
SomeFunction( printer.CStr() );
//------------------------------------------------
or
//------------------------------------------------
//enable at construction
XMLPrinter printer( file, true );         // to file
//XMLPrinter printer( NULL, true ); // to men
doc->Print( &printer );
SomeFunction( printer.CStr() );
//------------------------------------------------

The '\n' and space in Text or Attribute will be kept.
