Step 1. Add the JitPack repository to your build file

Add it in your root settings.gradle at the end of repositories:

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url 'https://jitpack.io' }
		}
	}

Add it in your settings.gradle.kts at the end of repositories:

	dependencyResolutionManagement {
		repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
		repositories {
			mavenCentral()
			maven { url = uri("https://jitpack.io") }
		}
	}

Add to pom.xml

	<repositories>
		<repository>
		    <id>jitpack.io</id>
		    <url>https://jitpack.io</url>
		</repository>
	</repositories>

Add it in your build.sbt at the end of resolvers:

 
    resolvers += "jitpack" at "https://jitpack.io"

Add it in your project.clj at the end of repositories:

 
    :repositories [["jitpack" "https://jitpack.io"]]

Step 2. Add the dependency

	dependencies {
		implementation 'com.github.open-android:jsoup:jsoup-1.10.2'
	}

	dependencies {
		implementation("com.github.open-android:jsoup:jsoup-1.10.2")
	}

	<dependency>
	    <groupId>com.github.open-android</groupId>
	    <artifactId>jsoup</artifactId>
	    <version>jsoup-1.10.2</version>
	</dependency>


                            
    libraryDependencies += "com.github.open-android" % "jsoup" % "jsoup-1.10.2"


                            
    :dependencies [[com.github.open-android/jsoup "jsoup-1.10.2"]]

使用效果

使用步骤

1. 在project的build.gradle添加如下代码(如下图)

allprojects {
    repositories {
        ...
        maven { url "https://jitpack.io" }
    }
}

2. 在Module的build.gradle添加依赖

compile 'com.github.open-android:Jsoup:jsoup-1.10.2'

3.演示步骤

a.测试用html内容如下

  <html>
   <head>
    <title>First parse</title>
   </head>
   <body>
    <p align="center">attribute parse</p>
    <p>text parse</p>
   </body>
  </html>

b.将演示代码复制到Activity的onCreate方法中

  //测试用html字符串
  String html = "<html><head><title>First parse</title></head>"
          + "<body><p align=\"center\">attribute parse</p>"
          + "<p>text parse</p></body></html>";

  //Jsoup解析获得Document对象
  Document doc = Jsoup.parse(html);

  System.out.println("解析出来的html:\n"+doc.toString());


  //获得head元素对象
  Element head = doc.head();

  //DOM方式获得第一个title元素
  Element title = head.getElementsByTag("title").first();

  //获得title元素中文本
  String text = title.text();
  System.out.println("title标签中文本: " + text);


  //---------------------------------------


  //获得body元素对象
  Element body = doc.body();

  //选择器语法查找p元素
  Elements lists = body.select("p");

  //遍历所有p元素，输出p元素文本
  for(Element p : lists){
      System.out.println("p元素文本: " + p.text());
  }


  //选择器语法查找第一个拥有align属性的p元素
  Element pElement = body.select("p[align]").first();

  //获得p元素align属性值
  String align = pElement.attr("align");
  System.out.println("p元素align属性值: " + align);

注意：如果解析指定url需要添加网络访问权限
