| Interface Summary |
| DocumentTraversal |
DocumentTraversal contains methods that create iterators and
tree-walkers to traverse a node and its children in document order (depth
first, pre-order traversal, which is equivalent to the order in which the start
tags occur in the text representation of the document). |
| NodeFilter |
Filters are objects that know how to "filter out" nodes. |
| NodeIterator |
Iterators are used to step through a set of nodes, e.g. the
set of nodes in a NodeList, the document subtree governed by a
particular Node, the results of a query, or any other set of
nodes. |
| TreeWalker |
TreeWalker objects are used to navigate a document tree or
subtree using the view of the document defined by their whatToShow
flags and filter (if any). |
