7.14 Example: Token-Based XML Decoding
Section 4.5 showed how to decode JSON documents into
Go data structures with the Marshal and Unmarshal
functions from the encoding/json package.
The encoding/xml package provides a similar API.
This approach is convenient when we want to construct a representation of
the document tree, but that’s unnecessary for many programs.
The encoding/xml package also provides a lower-level
token-based API for decoding XML.
In the token-based style, the parser consumes the input and produces a
