HtmlParser中的各類Filter(1)

全部的Filter均實現了NodeFilter接口，此接口只有一個方法Boolean accept(Node node),用於肯定某個節點 是否屬於此Filter過濾的範圍。 HtmlParser在org.htmlparser.filters包以內一共定義了16個不一樣的Filter，也能夠分爲幾類。

判斷類Filter: TagNameFilter

                  HasAttributeFilter

                  HasChildFilter

                  HasParentFilter

                  HasSiblingFilter

                  IsEqualFilter

邏輯運算Filter

                  AndFilter

                  NotFilter

                  OrFilter

                  XorFilter

其餘Filter:

                 NodeClassFilter

                 StringFilter

                 LinkStringFilter

                 LinkRegexFilter

                 RegexFilter

                 CssSelectorNodeFilter

除此以外，能夠自定義一些Filter,用於完成特殊需求的過濾
