Examples of org.htmlparser.filters.HasParentFilter

org.htmlparser.filters.HasParentFilter
This class accepts all tags that have a parent acceptable to another filter. It can be set to operate recursively, that is perform a scan up the node heirarchy looking for any ancestor that matches the predicate filter. End tags are not considered to be children of any tag.
