我是要拿取embed标签中的src的内容：
对上⾯两个帖⼦进⾏整合：
public static List<String> match(String source, String element, String attr) {
柬埔寨游记List<String> result = new ArrayList<String>();
String reg = "<" + element + "[^<>]*?\\s" + attr + "=['\"]?(.*?)['\"]?\\s.*?>";
Matcher m = pile(reg).matcher(source);
while (m.find()) {
String r = m.group(1);
result.add(r);
}
新鲜的英文return result;
}
public static void main(String[] args) throws MalformedURLException, IOException {
Document doc= Jsoup.par(new URL("/2018/11/1281e94387f5efb28be502f828edc032.html"),100000); String html = String();
// String source = "<a title=中国体育报 href=''>aaa</a><a title='北京⽇报' href=''>bbb</a>";
List<String> list = match(html, "embed", "src");
System.out.println(list);
}
其中⽤到的jar包：
<dependency>
<groupId>org.jsoup</groupId>
<artifactId>jsoup</artifactId>
<version>1.10.2</version>
</dependency>
