Problem

You need to modify the text content of a HTML document.

Solution

Use the text setter methods of Element:

Element div = doc.select("div").first(); // <div></div>
div.text("five > four"); // <div>five &gt; four</div>
div.prepend("First ");
div.append(" Last");
// now: <div>First five &gt; four Last</div>

Discussion

The text setter methods mirror the HTML setter methods:

Element.text(String text) clears any existing inner HTML in an element, and replaces it with the supplied text.
Element.prepend(String first) and Element.append(String last) add text nodes to the start or end of an element's inner HTML, respectively

The text should be supplied unencoded: characters like <, > etc will be treated as literals, not HTML.
