ARRAY(IXmlNode) ax
IXml x._create
IXmlNode e
int i

x.FromString(xml_str)
e=x.Path("/FreeFileSync/MainConfig/FolderPairs" ax 1)        
e.Add("Pair" "").Add("Left" "L")
e.Add("Pair" "").Add("Right" "R") ;; <==== second subnode, but does NOT generate desired result

;;......................
;Actual result:
;<Pair>
,;<Left>L</Left>
;</Pair>
;<Pair>
,;<Right>R</Right>
;</Pair>
;;......................
;Desired result: <<==================================
;<Pair>
,;<Left>d:\test</Left>
,;<Right>z:\test</Right>
;</Pair>
;<Pair>
,;<Left>L</Left>
,;<Right>R</Right>
;</Pair>
;;......................

x.ToString(_s)
out _s

Above in the green commented code you see what I want to achieve.

[Gintaras]

IXmlNode e2=e.Add("Pair" "")
e2.Add("Left" "L")
e2.Add("Right" "R")

or

e.Add("Pair" "").Add("Left" "L").Parent.Add("Right" "R")
