Development of the xml conversion program

There is a problem: suppliers send us prices in different formats. More precisely, the format is usually the same: xml, but the number of columns, their name usually differ. (I can send you some examples of prices, but there are ordinary tables in Exel)

The format of our unloading is different. It looks like this (an example of some positions):


-
-
,000,000
Delivery (Moscow)

200.
1 1 1 1
9999.

429

-
,000,000,000,000
Delivery over MKAD 1km

20.
1 1 1 1
9999.

1097

-
,000,000
Delivery (Moscow)

300.
1 1 1 1
0

707



The challenge is to write a program that can convert prices from our suppliers to the format we download (in the example above).
If necessary, I can send you the prices that the suppliers give us.
I am waiting for you to offer a price and specify the timeframe in which you can complete the task.
