Output to textboxes using XML data

Hi,
I have a Huge XML file generated outside my project and i need to be able to display the data in textboxes in realtime on my GUI.
ie. the data in the textbox needs to be constantly updated with a new value as soon as i press the button to activate the event handler.

I have been able only to output a chunk of the data in a multilined textbox but i need to display the separate fields in individual textboxes. I used a streaming reader in my trial so i do not know whether it is right or not.

So, please, if there are any gurus out there who can gimme a hand at this, i'll be eternally grately for your help....

By the way, do let me know what other information you need and i'll post them promptly. Thanks for your help in advance.

Regards to all
