java 使用jsoup处理html字符

依赖的jar
 <dependency>
            <groupId>org.jsoup</groupId>
            <artifactId>jsoup</artifactId>
            <version>1.8.3</version>
 </dependency>
测试:

public static void main(String[] args) {

String ssss = "<p><strong>测试线下班级问卷</strong></p><p><strong></strong>VR上班&nbsp;</p><p><img height=\"100\" src=\"/mfs/resource/public/40289b7e5a409828015a4099bada0001/2c9180e5622eba1701623c11753f0374/2018/08/15/2c9181e664cb4d6101653b10b9070a3e.png\" width=\"100\" /></p>";
 
System.out.println(Jsoup.parse(ssss).getElementsByTag("img").size());
 
System.out.println(Jsoup.parse(ssss).getElementsByTag("img").attr("src"));
//获取多个标签,遍历
int length = Jsoup.parse(ssss).select("img").size();
if (length > 0) {
    for (int i = 0; i < length; i++) {
        String s = Jsoup.parse(ssss).select("img").get(i).attr("src");
        System.out.println(s);
    }
}

}
