I must admit, that I have the strange feeling, that you do not know anything about Time Series Analysis. This is a non-trivial task and enough material for a whole lecture. Even if (not me, since I dont think I know enough in this area) xml-setups are posted, how do you want to judge the results ? How estimate the traps and properties of the used operators ?
its urgent for my final exam
If you grades depend on the results, I am afraid you cannot avoid to read some literature regarding Time Series Analysis.
just a few suggestions (pessimistic thoughts/warnings), this is not meant to be a flame...
