Enum ParseState

enum ParseState {
    Init,
    InsideMarkup,
    InsideText,
    InsideEmpty,
    Done,
}

Possible reader states. The state transition diagram (true and false shows value of Config::expand_empty_elements option):

Variants

Init

Initial state in which reader stay after creation. Transition from that state could produce a Text, Decl, Comment or Start event. The next state is always InsideMarkup. The reader will never return to this state. The event emitted during transition to InsideMarkup is a StartEvent if the first symbol not <, otherwise no event are emitted.

InsideMarkup

State after seeing the < symbol. Depending on the next symbol all other events could be generated.

After generating one event the reader moves to the InsideText state.

InsideText

State in which reader searches the < symbol of a markup. All bytes before that symbol will be returned in the Event::Text event. After that the reader moves to the InsideMarkup state.

InsideEmpty

This state is used only if option expand_empty_elements is set to true. Reader enters to this state when it is in a InsideText state and emits an Event::Start event. The next event emitted will be an Event::End, after which reader returned to the InsideText state.

Done

Reader enters this state when Eof event generated or an error occurred. This is the last state, the reader stay in it forever.
