goog.dom.TagIterator
A DOM tree traversal iterator. Starting with the given node, the iterator walks the DOM in order, reporting events for the start and end of Elements, and the presence of text nodes. For example:
<div>1<span>2</span>3</div>
Will return the following nodes: [div, 1, span, 2, span, 3, div] With the following states: [START, OTHER, START, OTHER, END, OTHER, END] And the following depths [1, 1, 2, 2, 1, 1, 0] Imagining | represents iterator position, the traversal stops at each of the following locations:
<div>|1|<span>|2|</span>|3|</div>|
The iterator can also be used in reverse mode, which will return the nodes and states in the opposite order. The depths will be slightly different since, like in normal mode, the depth is computed *after* the given node. Lastly, it is possible to create an iterator that is unconstrained, meaning that it will continue iterating until the end of the document instead of until exiting the start node.
