[番外]：帶你玩正則1--資料遍地是,看你取不取

張風捷特烈發表於2018-12-07

`謹言：正則沒有捷徑,唯一法可破，多想，多用，再多想，再多用`

最近想做個Android資源庫:toly_res開源庫，將一些常用字串和res資源收錄進去
所以找些字串練練手，做個資源儲備，順便磨一下我正則這把鏽跡斑斑的刀
正則的基礎知識我就不羅嗦了，一些常用符號不懂的可以自己查一查。
本文將用四個小例子介紹正則的使用

1.一百單八將的獲取

隨便從網上拷貝一份一百零八將的字串,怎麼把他優化到可用程度?

1.1:去除形如`3.`、`37.1`的字元

行尾點保留，將作為分割的標示。正則式："(\\d+\\.)(\\d{0,2}\\.?": 仔細分析一下，想要匹配到的東西：

情況1：---------------------：2.
情況2：---------------------：10.
情況3：---------------------：37.1
情況4：---------------------：44.8.
情況5：---------------------：46.10.

(\\d+\\.)----------說明匹配一個或多個數字，並且後面有點：情況1、情況2 get
(\\d{0,2}\\.?) ----說明匹配零到2個數字，並且後面有一個點或沒有點 情況3、情況4、情況5 get

效果就是選中了五種情況，看下效果：
String dest = str.replaceAll("(\\d+\\.)(\\d{0,2}\\.?)","");
複製程式碼

可見清爽了許多，然後用點.或者：進行切分：

1.2：切割每個人

切割過後資料就規整許多了

String[] strings = dest.split("\\.|：");
for (String string : strings) {
    if (string.contains("…")) {//過濾雜物
        System.out.println(string);
    }
}
複製程式碼

1.3：建立實體類承接資料

public class Hero {
    private String star;
    private String nickName;
    private String name;
    //get---set---toString略...
}
複製程式碼

String[] strings = dest.split("\\.|：");
for (String string : strings) {
    if (string.contains("…")) {//過濾雜物
        string= string.replaceAll("\\s", "");
        String[] split = string.split("…");
        heroes.add(new Hero(split[0], split[1], split[2]));
    }
}
System.out.println(heroes);
複製程式碼

好了，現在物件的列表都在手上，還不隨意擺弄嗎?

1.4為了方便使用，生成Json字串

implementation 'com.google.code.gson:gson:2.8.5'

GsonBuilder gsonBuilder = new GsonBuilder();
gsonBuilder.setPrettyPrinting();//美化輸出的json格式化
String json = gsonBuilder.create().toJson(heroes);
複製程式碼

從網上拷貝的介紹文到實體化，再轉為json字串，只用了這點程式碼，如果靠手動擋，估計要敲的夠嗆。
對於一些有規律而複雜的字串，優先考慮邏輯生成。才能以一敵百，解放雙手。

2.提取書名：(`千軍萬馬之中，直取上將首級`)

這個比較簡單，但挺經典的，直接上程式碼：
使用了Pattern+Matcher,對匹配字串進行組命名獲取,組命名方法:?<xxxxx>,獲取方式：matcher.group("xxxxx")

 public void book() {
     Set<String> books = new HashSet<>();
     File file = new File("C:\\Users\\Administrator\\Desktop\\100名著.txt");
     String str = readFile(file);
     Pattern pattern = Pattern.compile("《(?<result>.*?)》");//?<result>是取了一個組名
     Matcher matcher = pattern.matcher(str);
     while (matcher.find()) {
         String book = matcher.group("result");
         books.add(book);
     }
     StringBuilder sb = new StringBuilder("public static String[] " + "BOOKS" + " = new String[]{");
     books.forEach(s -> {
         sb.append("\"《" + s + "》\",");
     });
     sb.append("};");
     System.out.println(sb.toString());
 }
複製程式碼

很簡單就從複雜的文章中獲取了書名，而且排除了重複的，是不是四兩撥千斤

3.貼吧中郵箱的抓取

我用Python抓了一些網頁然後存在了檔案中，本文不注意如何獲取字串，核心在如何獲取有用資料

我們的目標：從6000多行字串中過濾出郵箱

3.1：郵箱格式的分析：

正則匹配式(我習慣為組取名字，這樣容易看，不然很容易暈,以後也容易看)：
(?<result>(?<first>\w)(?<username>[\w\.]{0,27})@(?<yuming>[\w]+\.(com|cn|com\.cn|net\.cn|edu|gov|org)))

 /**
  * 郵箱驗證
  * 1981462002@qq.com
  * toly.1994_king@123.com
  * ggl0228@163.com
  * wangshizhihao@foxmail.com
  * tchzw@126.com
  * 954007646@aw.com
  * 
  * 使用者名稱:字母、數字、下劃線、點
  * 使用者名稱首字元：字母
  * 使用者：長度小於28
  *
  * 域名：.com .cn .com.cn .net.cn .edu .gov .org
  */
複製程式碼

(?<result>(?<first>\w)(?<username>[\w\.]{0,27})@(?<yuming>[\w]+\.(com|cn|com\.cn|net\.cn|edu|gov|org)))

result組是我們需要的總匹配結果
first組是首字母的格式
username組是除首字母外的使用者名稱格式
yuming組是匹配域名

3.2：程式碼實現

@Test
public void email() {
    //檔案路徑
    File file = new File("C:\\Users\\Administrator\\Desktop\\郵箱.txt");
    String readFile = readFile(file);
    judgeEmail(readFile);
}
複製程式碼

private void judgeEmail(String target) {

    String regex = "(?<result>(?<first>\\w)(?<username>[\\w\\.]{0,27})@(?<yuming>[\\w]+\\.(com|cn|com\\.cn|net\\.cn|edu|gov|org)))";

    Pattern pattern = Pattern.compile(regex);
    Matcher matcher = pattern.matcher(target);
    while (matcher.find()) {
        System.out.println(matcher.group("result"));
    }
}
複製程式碼

3.2：連線成靜態字串陣列

private void judgeEmail(String target) {
    String regex = "(?<result>(?<first>\\w)(?<username>[\\w\\.]{0,27})@(?<yuming>[\\w]+\\.(com|cn|com\\.cn|net\\.cn|edu|gov|org)))";
    Pattern pattern = Pattern.compile(regex);//?<result>是取了一個組名
    Matcher matcher = pattern.matcher(target);
    StringBuilder sb = new StringBuilder("public static String[] " + "EMAIL" + " = new String[]{");
    while (matcher.find()) {
        sb.append("\"" + matcher.group("result") + "\",");
    }
    sb.append("};");
    System.out.println(sb.toString());
}

4.從豆瓣電影的html獲取資料

注：喜歡Python爬蟲的童鞋不要噴，收起你的唾沫，這裡主要演示正則的分析與使用

4.1：開啟豆瓣電影，隨便找一頁，將原始碼拷貝出來(當然你也可以通過程式碼獲取網頁,這無關緊要)

拷貝出來嚇一跳，竟然4000多行，嚇得我手一抖，沒關係分析分析，切切就少了

4.2：主要的條目如下

用上面的套路，把中間的東西擠出來，一共獲得104組資料

@Test
public void movie() {

    Set<String> movies = new HashSet<>();
    File file = new File("C:\\Users\\Administrator\\Desktop\\豆瓣.txt");
    String str = readFile(file);

    Pattern pattern = Pattern.compile("class=\"item\" target=\"_blank\"(?<result>(.|\\s)*?)</a>");//?<result>是取了一個組名
    Matcher matcher = pattern.matcher(str);
    while (matcher.find()) {
        String result = matcher.group("result");
        System.out.println(result);
        movies.add(result);
    }
}
複製程式碼

4.3：只要將條目再加工，便可以獲取資訊了

方法詳見下：

4.4：建立實體類，承接資料

public class Movie {
    private String name;
    private String imgUrl;
    private String star;
    //get---set---toString略...
}
複製程式碼

@Test
public void movie() {
    ArrayList<Movie> movies = new ArrayList<>();
    File file = new File("C:\\Users\\Administrator\\Desktop\\豆瓣.txt");
    String str = readFile(file);
    Pattern pattern = Pattern.compile("class=\"item\" target=\"_blank\"(?<result>(.|\\s)*?)</a>
    Matcher matcher = pattern.matcher(str);
    while (matcher.find()) {
        Movie movie = new Movie();
        String result = matcher.group("result");
        //獲取名字
        Pattern nameP = Pattern.compile("alt=\"(?<name>(.|\\s)*?)\"");//?<result>是取
        Matcher nameM = nameP.matcher(result);
        while (nameM.find()) {
            String name = nameM.group("name");
            if (!name.contains("<%=")) {
                movie.setName(name);
            }
        }
        //獲取圖片
        Pattern imgurlP = Pattern.compile("<img src=\"(?<imgurl>(.|\\s)*?)\"");
        Matcher imgurlM = imgurlP.matcher(result);
        while (imgurlM.find()) {
            String imgurl = imgurlM.group("imgurl");
            if (imgurl.contains("http") && !imgurl.contains("ic_new.png")) {
                movie.setImgUrl(imgurl);
            }
        }
        //獲取評分
        Pattern starP = Pattern.compile("<strong>(?<star>(.|\\s)*?)</strong>");
        Matcher starM = starP.matcher(result);
        while (starM.find()) {
            String star = starM.group("star");

[番外]：帶你玩正則1--資料遍地是,看你取不取

謹言：正則沒有捷徑,唯一法可破，多想，多用，再多想，再多用

1.一百單八將的獲取

1.1:去除形如3.、37.1的字元

1.2：切割每個人

1.3：建立實體類承接資料

1.4為了方便使用，生成Json字串

2.提取書名：(千軍萬馬之中，直取上將首級)

3.貼吧中郵箱的抓取

3.1：郵箱格式的分析：

3.2：程式碼實現

3.2：連線成靜態字串陣列

4.從豆瓣電影的html獲取資料

4.1：開啟豆瓣電影，隨便找一頁，將原始碼拷貝出來(當然你也可以通過程式碼獲取網頁,這無關緊要)

4.2：主要的條目如下

4.3：只要將條目再加工，便可以獲取資訊了

4.4：建立實體類，承接資料

4.5:轉化成Json字串備用
