reading xml data from dll file using winform application

reading xml data from dll file using winform application

I have got a xml data file which contains the data I need to display into
grid in winform application. Now, I don't want to read xml directly and
parse using xml functions and display into grid, but instead, I have got a
dll file which has got the functions that needs to use to read the xml
file and then display into grid.
for example:
dll file has a function - "vehicleJourney" and has a property - "lineref"
now this vehicleJourney should be matched as a node in xml file and its
childnode within the parent node as lineref and so on, to build a data
structure fill the grid and display the data .
Please ask me, in case of any doubt.
Thanks in advance
