| short | acceptNode(org.w3c.dom.Node node)Internal function.
The node whatToShow and the filter are combined into one result.
/***
7.1.2.4. Filters and whatToShow flags
Iterator and TreeWalker apply whatToShow flags before applying Filters. If a node is rejected by the
active whatToShow flags, a Filter will not be called to evaluate that node. When a node is rejected by
the active whatToShow flags, children of that node will still be considered, and Filters may be called to
evaluate them.
