Remove Duplicate Nodes

[Sudeesh]

Dear All,

I have an XML file which contains duplicates node for a single ID. I would like to compare 2 particular field values from both these nodes and based on the result, I would like to print only one node in output. Please find the below XML File.

************************************************** ******

In the above sample, there are 2 nodes for the ID "123456". In this case, I need to compare the values of "Information/End_Date" of first Node and "Status/Begin_Date" of 2nd Node. If "Begin_Date" is greater than "End_Date", pass the first Node, else vice versa.

Could you please help me!
