I'm trying to get nested hierarchy data from large XML file and show it in a tree structure in MVC application.

I need to considerate performance issue as well, because I'm using a large xml file.
I started with parsing the xml with XmlReader and now i thinking to use XmlSerializer, what do you think?
If the hierarchy in the xml file will be changing when i will add / remove nodes, how to build the xml file that the XmlSerializerwill recognize all the children?

in the end i need to show in the browser tree with expand and collapse ability, and each time to get the expanded nodes from my xml...

Thanks!
