There is no organization in displaying the xml structure in the file (New line, indent...).The xml data is saved in this way\[code\]<B1><BB1>BBB1</BB1></B1><B2><BB2>BBB2</BB2></B2><B3><BB3>BBB3</BB3></B3>\[/code\]How to make the minixml saving the xml data in the following way ?\[code\]<B1> <BB1>BBB1</BB1></B1><B2> <BB2>BBB2</BB2></B2><B3> <BB3>BBB3</BB3></B3>\[/code\]
