java.lang.Object org.htmlparser.filters.HasParentFilter
public class 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.
Field Summary | |
---|---|
protected NodeFilter |
mParentFilter
The filter to apply to the parent. |
protected boolean |
mRecursive
Performs a recursive search up the node heirarchy if true . |
Constructor Summary | |
---|---|
HasParentFilter()
Creates a new instance of HasParentFilter. |
|
HasParentFilter(NodeFilter filter)
Creates a new instance of HasParentFilter that accepts nodes with the direct parent acceptable to the filter. |
|
HasParentFilter(NodeFilter filter,
boolean recursive)
Creates a new instance of HasParentFilter that accepts nodes with a parent acceptable to the filter. |
Method Summary | |
