我对HtmlParser 提取网页各属性的总结及示例说明

 /**
  * 属性过滤器
  * @param parser
  * @param obj
  *            如:NodeFilter filterTable = new TagNameFilter("tr"); NodeFilter filterHeight =
  *            new HasAttributeFilter("height", "100"); NodeFilter filterClass = new
  *            HasAttributeFilter("class", "tt"); new
  *            NodeFilter[]{filterTable,filterHeight,filterClass};
  * @return
  * @throws ParserException
  */
 public static NodeList parserPro(Parser parser, NodeFilter[] obj)
   throws ParserException
 {
  NodeFilter filter = new AndFilter(obj);
  return parser.extractAllNodesThatMatch(filter);
 }
