使用HtmlParser 提取百度貼吧中的郵箱地址

經測試，實際用時1秒左右

private static final Pattern p = Pattern.compile("\\w+([-+.]\\w+)*@\\w+([-.]\\w+)*\\.\\w+([-.]\\w+)*");public static ArrayList<String> extractEmail(int id,int start,int end){ArrayList<String> list = new ArrayList<String>();try {for (int i = start; i <= end; i++) {Parser parser = new Parser("http://tieba.baidu.com/p/"+id+"?pn="+i);NodeFilter filter = new RegexFilter("\\w+([-+.]\\w+)*@\\w+([-.]\\w+)*\\.\\w+([-.]\\w+)*");NodeList nodes = parser.extractAllNodesThatMatch(filter);if (nodes.size() > 0) {for (NodeIterator ni = nodes.elements(); ni.hasMoreNodes();) {Matcher m = p.matcher(ni.nextNode().toHtml());if (m.find()) {list.add(m.group());}}}}} catch (ParserException e) {}return list;}
