Examples of org.htmlparser.filters.HasChildFilter

org.htmlparser.filters.HasChildFilter
This class accepts all tags that have a child acceptable to the filter. It can be set to operate recursively, that is perform a scan down through the node heirarchy in a breadth first traversal looking for any descendant that matches the predicate filter (which stops the search).
