But given that Element is a value +object, we want to eschew methods and have public exposed variables. + +We also considered the following, where xml types were not value objects, and we used +intelligent accessor methods to extract information and for performance. +*** WE DECIDED AGAINST THIS. *** + type Attr struct { + Name Name + Value string + } + // Element is a ValueObject: There are no accessor methods. + // Make element self-contained. + type Element struct { + Name Name + attrsMap map[string]string // where key is "Space Local" + attrs []Attr + childrenT []string + childrenE []Element + childrenI []int // each child is a index into T or E. + } + func (x *Element) child(i) interface{} // returns string or *Element + +// ------------------ + +Per XML spec and our default handling, white space is always treated as +insignificant between elements, except in a text node.

In this mode: + - struct name maps to element name (or tag-info from _struct field) + - fields are mapped to child elements or attributes + +A map is either encoded as attributes on current element, or as a set of child elements. +Maps are encoded as attributes iff their keys and values are primitives (number, bool, string). + +A list is encoded as a set of child elements. + +Primitives (number, bool, string) are encoded as an element, attribute or text +depending on the context. + +Extensions must encode themselves as a text string. + +Encoding is tough, specifically when encoding mappings, because we need to encode +as either attribute or element. To do this, we need to default to encoding as attributes, +and then let Encoder inform the Handle when to start encoding as nodes. +i.e. Encoder does something like: + + h.EncodeMapStart() + h.Encode(), h.Encode(), ... + h.EncodeMapNotAttrSignal() // this is not a bool, because it's a signal + h.Encode(), h.Encode(), ... + h.EncodeEnd() + +Only XMLHandle understands this, and will set itself to start encoding as elements. + +This support extends to maps.
