        Parser parser = new Parser(url);
        NodeFilter filter = new TagNameFilter("div");
        NodeList nodes = parser.extractAllNodesThatMatch(filter);

        String nodex = "";
        if(nodes!=null){
            for
 
(int i=0;i<nodes.size();i++){

                nodex = node.toString();
                System.out.println(nodex);
            }
        }
    }

    public static void main(String[] args) throws ParserException, IOException {

    public static void getContent(String url)throws ParserException,IOException{
        Parser parser = new Parser(url);
        NodeFilter innerfilter = new TagNameFilter("div");
        NodeFilter filter = new HasChildFilter(innerfilter);
        NodeList nodes = parser.extractAllNodesThatMatch(filter);

        String nodex = "";
        if(nodes!=null){
            for(int i=0;i<nodes.size();i++){
                Node node = nodes.elementAt(i);
                nodex = node.toString();

                System.out.println(nodex);
            }
        }

    }
    public static void main(String[] args) throws ParserException, IOException {
        String url="http://yemacaijing.baijia.baidu.com/article/598342";
        getContent(url);
    }

}

3、HasAttributeFilter

import org.htmlparser.NodeFilter;
import org.htmlparser.Parser;
import org.htmlparser.filters.HasAttributeFilter;
import org.htmlparser.util.NodeList;
import org.htmlparser.util.ParserException;

        NodeFilter filter = new HasAttributeFilter("href");
        NodeList nodes = parser.extractAllNodesThatMatch(filter);

        String nodex = "";
        if(nodes!=null){
            for(int i=0;i<nodes.size();i++){
                Node node = nodes.elementAt(i);
                nodex = node.toString();

                System.out.println(nodex);
            }
        }

    }
    public static void main(String[] args) throws ParserException {
