Getting parts of an xml file and bundle them up in a new one

[Trajcek]

I'm trying to create a new xml file with parts from other xml files. For example i got these 2 xml files:file 1:\[code\]<root> <persons> <person1> <name> </name> <address> </address> <number> </number> </person1> <person2> <name> </name> <address> </address> <number> </number> </person2> </persons></root>\[/code\]file 2:\[code\]<registration> <results> <result1> <test1> </test1> <Test2> </test2> </result1> <result2> <test1> </test1> <Test2> </test2> </result2> </results></registration>\[/code\]The new xml file should look like this:\[code\]<combined> <persons> <person1> <name> </name> <address> </address> <number> </number> </person1> <person2> <name> </name> <address> </address> <number> </number> </person2> </persons> <results> <result1> <test1> </test1> <Test2> </test2> </result1> <result2> <test1> </test1> <Test2> </test2> </result2> </results></combined>\[/code\]How can I accomplish this in C# with \[code\]xmldocument\[/code\]?EDITSome more information, the nodes "persons" and "results" should be put in the new xml document (including "persons" and "results").
