I have been unable to compile this SAX parser for 5 days now.

Answer 1

Why do you need so many type classes? All *-price are stupid maps Strung, Float...
No need to wrap each tag in a class.
And if the file is healthy, then use Stax.
Personally, I don't see anything complicated.
Better yet combine with jaxb https://stackoverflow.com/questions/25643097/can-a...

Answer 2

You open the manual and write.
