How to count the number of options in a select DOM Element in Java
Hi folks is there a way to count the number of options in a select DOM Element retrieved using JSoup or Java by itself after having the file saved in a text file?
Any help with this would be appreciated.
Cheers!

'Elements' is essentially a List, so the size() method can be used if you reverse the 'serialization' process

The select would be something like the following if that helps...

select#jump would be the key then, not #jump
