现在的网站千奇百怪，什么样格式的都有，需要提取网页中的列表数据，有时候挨个分析处理很头疼，本文是一个页面结构分析的程序，可以分析处理页面大致列表结构。
废话不多说，我也不会说，show me code，code is terrible，so what hahaha。-------jstarseven
1.抽取元素dom结构框架
1 /** 2 * 分析元素dom结构框架 3 * 4 * @param node 5 * @return 6 */ 7 public String filterHtml(Element node) { 8 //去除节点的属性值 9 Document new_node = Jsoup.parse(node.outerHtml()); 10 Elements elements = new_node.getAllElements(); 11 for (Element item : elements) { 12 Attributes attributes = item.attributes(); 13 for (Attribute a : attributes) { 14 if (a.getKey().equals(KeysEnum.attr_scroce)) { 15 item.removeAttr(a.getKey()); 16 continue; 17 } 18 a.setValue(StringUtils.EMPTY); 19 } 20 } 21 //去除注释节点,节点文本内容 22 String str_new = new_node.outerHtml().replaceAll("<!--?(.*?)-->", ""); 23 str_new = str_new.replaceAll("\s*", ""); 24 str_new = str_new.replaceAll(">(.*?)<", "><"); 25 return str_new; 26 }
2.采用动态规划处理两个字符串相似度
1 public class SimilarDegree { 2 3 public static final double degree = 0.8; 4 5 /** 6 * 采用动态规划的方法解决 7 * 8 * @param source 9 * @param target 10 * @return 11 */ 12 public static int EditDistance(String source, String target) { 13 char[] sources = source.toCharArray(); 14 char[] targets = target.toCharArray(); 15 int sourceLen = sources.length; 16 int targetLen = targets.length; 17 int[][] d = new int[sourceLen + 1][targetLen + 1]; 18 for (int i = 0; i <= sourceLen; i++) { 19 d[i][0] = i; 20 } 21 for (int i = 0; i <= targetLen; i++) { 22 d[0][i] = i; 23 } 24 25 for (int i = 1; i <= sourceLen; i++) { 26 for (int j = 1; j <= targetLen; j++) { 27 if (sources[i - 1] == targets[j - 1]) { 28 d[i][j] = d[i - 1][j - 1]; 29 } else { 30 //插入 31 int insert = d[i][j - 1] + 1; 32 //删除 33 int delete = d[i - 1][j] + 1; 34 //替换 35 int replace = d[i - 1][j - 1] + 1; 36 d[i][j] = Math.min(insert, delete) > Math.min(delete, replace) ? Math.min(delete, replace) : 37 Math.min(insert, delete); 38 } 39 } 40 } 41 return d[sourceLen][targetLen]; 42 } 43 44 public static void main(String[] args) { 45 System.out.println(EditDistance("html > body > ul > li.proiect_item:nth-child(1) > div.item_row.item_row_title > div:nth-child(1) > a", 46 "html > body > ul > li.proiect_item:nth-child(2) > div.item_row.item_row_title > div:nth-child(1) > a")); 47 } 48 49 }
3.对网页中每个节点的一级孩子节点分类
1 /** 2 * 统计列表下各个一级节点类型及个数 3 * 4 * @param node 5 * @return 6 */ 7 private Map<String, Integer> getGroupNode(Element node) { 8 Map<String, Integer> map = new HashMap<String, Integer>(); 9 Elements children = node.children(); 10 for (Element item : children) { 11 if (KeysEnum.input.equalsIgnoreCase(item.tagName()) || KeysEnum.br.equalsIgnoreCase(item.tagName()) 12 || KeysEnum.script.equalsIgnoreCase(item.tagName()) || KeysEnum.link.equalsIgnoreCase(item.tagName()) 13 || KeysEnum.style.equalsIgnoreCase(item.tagName()) || KeysEnum.meta.equalsIgnoreCase(item.tagName()) 14 || KeysEnum.select.equalsIgnoreCase(item.tagName()) || KeysEnum.option.equalsIgnoreCase(item.tagName()) 15 || KeysEnum.video.equals(item.tagName()) || KeysEnum.audio.equals(item.tagName()) 16 || KeysEnum.textarea.equals(item.tagName())) continue; 17 String key = filterHtml(item); 18 if (map.containsKey(key)) { 19 map.put(key, (Integer) map.get(key) + 1); 20 } else { 21 boolean is_like = false; 22 for (String map_key : map.keySet()) { 23 int dis = SimilarDegree.EditDistance(key, (String) map_key); 24 float v = (float) (key.length() - dis) / key.length(); 25 if (v > SimilarDegree.degree) { 26 map.put(map_key, (Integer) map.get(map_key) + 1); 27 is_like = true; 28 break; 29 } 30 } 31 if (!is_like) map.put(key, 1); 32 } 33 } 34 return map; 35 }
4.处理网页中每个元素的叶子节点
1 /** 2 * 获取叶子节点选择器 3 * 4 * @param node 5 */ 6 public static List<String> getYeziNodeSel(Element node) { 7 List<String> list = new ArrayList<String>(); 8 Elements all = node.getAllElements(); 9 for (Element item : all) { 10 if (item.children().isEmpty()) list.add(item.cssSelector()); 11 } 12 return list; 13 }
5.时间提取工具类
1 /** 2 * jstarseven 3 * 通用时间处理类 return Date 4 * */ 5 public class DateParser { 6 private static int timezone = 0; 7 private static final Pattern[] DPTN = { 8 9 Pattern.compile( 10 "(\d{1,2})[\s\-\/](\d{1,2})[\s\-\/](20\d{2})\s{0,2}((\d{1,2})[:\s](\d{1,2})[:\s]?(\d{1,2})?)?"), 11 12 Pattern.compile( 13 "((20)?\d{2}) {0,2}[\.\-/年] {0,2}(\d{1,2}) {0,2}[\.\-/月] {0,2}(\d{1,2}) {0,2}[日 \s]{0,2}((上午)|(下午))?\s{0,2}((\d{1,2})[:\s时](\d{1,2})[:\s分]?(\d{1,2})?)?"), 14 15 Pattern.compile("((20)?\d{2})/(\d{2})(\d{2})"), 16 17 Pattern.compile( 18 "(\d{1,2})[\.\-\s/月](\d{1,2})[日\s]{0,2}((上午)|(下午))?\s{0,2}((\d{1,2})[:\s](\d{1,2})[:\s]?(\d{1,2})?)?"), 19 20 Pattern.compile("([今前昨]天)?\s{0,4}(\d{1,2})[:\s]{1,3}(\d{1,2})[:\s]?(\d{1,2})?"), 21 22 Pattern.compile("[今前昨]天"), 23 24 Pattern.compile("((\d{1,2})|(半))\s*个?([天秒小时分钟周月年]{1,2})前"), 25 26 Pattern.compile("(\d{1,2})小?时(\d{1,2})分钟?前"), 27 28 Pattern.compile("(20\d{2})[01]?(\d{2})[012]?(\d{2})") }; 29 30 public static Date parse(Object obj) { 31 if (obj == null) { 32 return null; 33 } 34 if ((obj instanceof Date)) { 35 return (Date) obj; 36 } 37 if ((obj instanceof Number)) { 38 return new Date(((Number) obj).longValue()); 39 } 40 String str = ((String) obj).trim(); 41 if ((str.length() == 0) || ("null".equalsIgnoreCase(str))) { 42 return null; 43 } 44 str = transZH(str); 45 Calendar c = Calendar.getInstance(); 46 c.setTimeInMillis(System.currentTimeMillis()); 47 48 Matcher mt = DPTN[0].matcher(str); 49 if (mt.find()) { 50 int date = Integer.parseInt(mt.group(2)); 51 if ((date == 0) || (date > 31)) { 52 return null; 53 } 54 int month = Integer.parseInt(mt.group(1)); 55 if (month <= 0) { 56 return null; 57 } 58 if (month > 12) { 59 if ((date > 0) && (date <= 12) && (month < 32)) { 60 int tmp = month; 61 month = date; 62 date = tmp; 63 } else { 64 return null; 65 } 66 } 67 String sy = mt.group(3); 68 int year = Integer.parseInt(sy); 69 if ((year < 2000) || (year > 2099)) { 70 return null; 71 } 72 String hms = mt.group(4); 73 if ((hms == null) || (hms.length() == 0)) { 74 c.set(year, month - 1, date, timezone > 0 ?

6.自定义比较器对网页所有元素排序，发现结果靠前的基本都是列表元素
比较器：按照疑似列表的可能性

9.上述第7步返回的结果实例：
拿cnblog首页做测试，返回结果：
字段解释：
home_url ：分析的页面地址
tag_name ：当前页面的类型，多数情况下不正确，我只是拿home_url和页面的url比对，取了对应的text
list：页面中疑似列表元素
list_sel：页面中疑似列表元素的选择器
list_dom：页面中疑似列表元素的 一级孩子节点元素，叶子元素选择器
ifrs：页面中包含iframe分析的结果，没有则为空

10.上述第8步标记文件效果：
红色虚线框起来的是返回的json结果中list中的list_sel选择器选中的元素
分析结果统计：
处理了将近1万的网站发现，大致的网页列表结构可以发现，平时时间大致在2-3s左右，因为用的是jsoup访问的网页，包含了网页响应的时间，时间复杂度待优化，
分析结果对于一些比较复杂乱的网页支持有待加强，代码写的比较乱，有待优化，应该会有更好的处理方式，还请指教，相互学习交流。
