Exercise 7.18 (P215)

Using the token-based decoder API, write a program that will read an arbitrary XML document and construct a tree of generic nodes that represents it. Nodes are of two kinds: CharData nodes represent text strings, and Element nodes represent named elements and their attributes. Each element node has a slice of child nodes.

You may find the following declarations helpful.

    import "encoding/xml"
    type Node interface{} // CharData or *Element
    type CharData string
    type Element struct {
        Type     xml.Name
        Attr     []xml.Attr
        Children []node
    }
