4 New Member

Hi,
I have one problem when i'm trying to loop thorugh the child nodes in a XML string in JAVA. The first Loop is working but in the child node there i want to loop and get the values but it doesn't change the value. Always print the first child node value. I got the length of the child nodes but ..... Pls see the xml string.

I want to print the service class and availabilty in the each flightinfo node. I got he lenth of flightinfo also the infoonClasses. But it always print the first Class and Avalibilty in the entire loop.

can any on tell me how can loopthrough the child nodes......
