设置HTML的一个元素

Problem

You need to modify the HTML of an element.

Solution

Use the HTML setter methods in Element:

Element div = doc.select("div").first(); // <div></div>
div.html("<p>lorem ipsum</p>"); // <div><p>lorem ipsum</p></div>
div.prepend("<p>First</p>");
div.append("<p>Last</p>");
// now: <div><p>First</p><p>lorem ipsum</p><p>Last</p></div>

Element span = doc.select("span").first(); // <span>One</span>
span.wrap("<li><a href='http://example.com/'></a></li>");
// now: <li><a href="http://example.com"><span>One</span></a></li>

Discussion

• Element.html(String html) clears any existing inner HTML in an element, and replaces it with parsed HTML.

• Element.prepend(String first) and Element.append(String last) add HTML to the start or end of an element's inner HTML, respectively

• Element.wrap(String around) wraps HTML around the outer HTML of an element.

You can also use the Element.prependElement(String tag) andElement.appendElement(String tag) methods to create new elements and insert them into the document flow as a child element.
