这是我的程序:

package com.dcvsolution.crawler.songkhoedotvn;

public class GetCategories {

    public static void main(String[] args) throws IOException {
        // Bait link.
        String baitLink = "http://songkhoe.vn/";
        // If we prefer mobile-site option (default of "songkhoe.vn" when use
        // Jsoup).
        // Document doc = Jsoup.connect(url).get();
        // If we prefer full-page format web-page option.
        // Đánh lừa trang web, đây là đang duyệt web trên PC, là Google.
        Document doc = Jsoup.connect(baitLink)
                .userAgent("Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:45.0) Gecko/20100101 Firefox/45.0")
                .referrer("http://www.google.com").get();
        Elements links = doc.select("a[href]");

        // Push data to a set for unique result.
        Set<Element> uniqueSet = new HashSet<Element>(links);


        // Iterate through above set.
        for (Element link : uniqueSet) {
            CommonUtil.printByFoundry("%s", link.attr("abs:href"), CommonUtil.trim(link.text(), 3500));
            // Posts post = new Posts();

帮我选择仅包含字符串“/chuyen-muc-”的字符串。

我尝试:

Elements links = doc.select("a[href]:contains(chuyen-muc-)");

但不工作

Answer 1

改用这个 CSS 查询:

a[href*=chuyen-muc-]

DEMO

您可以使用正则表达式来更具体:

a[href~=chuyen-muc-(dinh|lam)]

上述 CSS 查询将只返回包含 chuyen-muc-dinh 或 chuyen-muc-lam 的链接。
