I have an XML file and I would like to merge two different CONTACT child nodes. I have checked these websites it shows how to merge two different xml files into a single file. http://www2.informatik.hu-berlin.de/~obecker/XSLT/#merge Merge XML documents In my case this is my first contact in the xml file: <CONTACT> <PDE-Identity>N65539</PDE-Identity> <FirstName>Arun_niit</FirstName> <LastName>Arun_niit</LastName> <Facebook-ID/> <EMAILS> <EMail> <Type>yahoo</Type> <Value>[email protected]</Value> </EMail> </EMAILS> </CONTACT> This is the second contact in the file: <PDE-Identity>N65567</PDE-Identity> <FirstName>Arun_niit</FirstName> <LastName>Ramanathan</LastName> <Facebook-ID/> <EMAILS> <EMail> <Type>gmail</Type> <Value>[email protected]</Value> </EMail> <EMail> <Type>yahoo</Type> <Value>[email protected]</Value> </EMail> </EMAILS> </CONTACT> <CONTACT> I know both of the contacts are belongs to the same person. How can i merge these two contacts in the same xml file. Original XML File: <?xml version="1.0" encoding="UTF-8"?> <CONTACTS> <CONTACT> <PDE-Identity>N65539</PDE-Identity> <FirstName>Arun_niit</FirstName> <LastName>Arun_niit</LastName> <Facebook-ID/> <EMAILS> <EMail> <Type>yahoo</Type> <Value>[email protected]</Value> </EMail> </EMAILS> </CONTACT> <CONTACT> <PDE-Identity>N65567</PDE-Identity> <FirstName>Arun_niit</FirstName> <LastName>Ramanathan</LastName> <Facebook-ID/> <EMAILS> <EMail> <Type>gmail</Type> <Value>[email protected]</Value> </EMail> <EMail> <Type>yahoo</Type> <Value>[email protected]</Value> </EMail> </EMAILS> </CONTACT> <CONTACT> <PDE-Identity>N65567</PDE-Identity> <FirstName>Rangarajkarthik</FirstName> <LastName>karthik Rangaraj</LastName> <Facebook-ID/> <EMAILS> <EMail> <Type>gmail</Type> <Value>[email protected]</Value> </EMail> <EMail> <Type>yahoo</Type> <Value>[email protected]</Value> </EMail> </EMAILS> </CONTACT> <CONTACTS>
