ITraversal class

ITraversal class

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. The set of nodes to be iterated is determined by the implementation of the NodeIterator. DOM Level 2 specifies a single NodeIterator implementation for document-order traversal of a document subtree. Instances of these iterators are created by calling DocumentTraversal .createNodeIterator().

The ITraversal type exposes the following members:

Properties

PropertyDescription
rootThe root node of the NodeIterator, as specified when it
was created.
what_to_showThis attribute determines which node types are presented via the
iterator. The available set of constants is defined in the
NodeFilter interface. Nodes not accepted by
whatToShow will be skipped, but their children may still
be considered. Note that this skip takes precedence over the filter,
if any.
filterThe NodeFilter used to screen nodes.
