css - 如何使用选择器 CSS 查询解析特定链接

Question

Note : A similar question has been asked at JSoup:How to Parse a Specific Link. However, I have a more specific variation of this question - Please read ahead

要解析特定站点链接，我需要使用Document select() 方法以最有效的方式获取此数据。我应该使用什么选择器 CSS 查询来实现此目的？

这是我未编译的尝试之一:

import org.jsoup.*;
import org.jsoup.nodes.*;
import org.jsoup.select.*;
import org.jsoup.Connection.*;

import java.io.*;
import java.util.*;

public class WebInteraction {

  public Document accLogin(Account ac, String url) {

    Document doc;
    doc = Jsoup.connect(url).data("name", ac.username, "code", ac.pass).method(Method.POST).execute().parse();

    Elements verify = doc.select(a[href*="/logout"]);

  }
}

错误信息:

$ javac WebInteraction.java
WebInteraction.java:17: error: cannot find symbol
    Elements verify = doc.select(a[href*="/logout"]);
                                 ^
  symbol:   variable a
  location: class WebInteraction
WebInteraction.java:17: error: cannot find symbol
    Elements verify = doc.select(a[href*="/logout"]);
                                   ^
  symbol:   variable href
  location: class WebInteraction
2 errors

Answer 1

以下行存在语法错误:

Elements verify = doc.select(a[href*="/logout"]);

修改如下:

Elements verify = doc.select("a[href*=/logout]");

/logout 不需要双引号。
