@DOMNameAttribute(name="acceptNode") short acceptNode(Node n)
Test whether a specified node is visible in the logical view of a TreeWalker or NodeIterator. This function will be called by the implementation of TreeWalker and NodeIterator; it is not normally called directly from user code. (Though you could do so if you wanted to use the same filter to guide your own application logic.)
n- node to check to see if it passes the filter or not.
