quesions about data logging shield

Hi guys, I just bought the data logging recorder shield V1.0 to store data for my Mega board. But I got no clue how to use this. Can anyone tell me how to write and read the data ? It could be wonderful if anyone can just write a program for me.

SD library. examples.

What you want to write?

I'm not a beginner. I write a log in XML - file. Than I open html-page wich draw me a plot(Ethernet shield).

Also you can open xml in excel. And draw the plot with excel.
