Answer 1

Its actually necessary as well not. Why? If you are working in any static application like gaming and others where you don't need any call web service to fetch server side data then you are fine with no learning.

But if you want server data using web service, you definitely need to learn how xml works.

In webservice, two kind of structure are used to pass data.

XML
JSON
JSON is light weight then XML.
