DTMNodeIterator
gives us an implementation of the DTMNodeIterator which returns DOM
nodes.
Please note that this is not necessarily equivlaent to a DOM NodeIterator operating over the same document. In particular:
- If there are several Text nodes in logical succession (ie, across CDATASection and EntityReference boundaries), we will return only the first; the caller is responsible for stepping through them. (%REVIEW% Provide a convenience routine here to assist, pending proposed DOM Level 3 getAdjacentText() operation?)
- Since the whole XPath/XSLT architecture assumes that the source document is not altered while we're working with it, we do not promise to implement the DOM NodeIterator's "maintain current position" response to document mutation.
- Since our design for XPath NodeIterators builds a stateful filter directly into the traversal object, getNodeFilter() is not supported.
State: In progress!!
