无涯教程-jsoup - 设置文本内容下面的示例将HTML解析为Document对象之后，使用text，prepend

下面的示例将HTML解析为Document对象之后，使用text，prepend，append方法将内容写入到指定元素内。

Document document=Jsoup.parse(html);
Element div=document.getElementById("sampleDiv");     
div.text("This is a sample content.");   
div.prepend("Initial Text.");
div.append("End Text.");

元素对象代表dom元素，并提供各种方法来将html设置，添加或添加到dom元素。

使用您选择的任何编辑器在C:/> jsoup中创建以下Java程序。

JsoupTester.java

import org.jsoup.Jsoup;
import org.jsoup.nodes.Document;
import org.jsoup.nodes.Element;
public class JsoupTester {
public static void main(String[] args) {

}
}

使用 javac 编译器编译类，如下所示:

C:\jsoup>javac JsoupTester.java

现在运行JsoupTester以查看输出。

C:\jsoup>java JsoupTester

查看输出。

Outer HTML Before Modification :
<div id="sampleDiv">
 <a id="googleA" href="www.google.com">Google</a>
</div>
Outer HTML After Modification :
<div id="sampleDiv">
 This is a sample content.
</div>
After Prepend :
<div id="sampleDiv">
 Initial Text.This is a sample content.
</div>
After Append :
<div id="sampleDiv">
 Initial Text.This is a sample content.End Text.
</div>
