      <div><font>One</font> <font><a href="/">Two</a></font></div>

      Returns:
      this, for chaining
      See Also:
      Element.empty(), remove()
    • remove

      public Elements remove()

      doc.select("p").remove();
      HTML = <div> <img /></div>

      Note that this method should not be used to clean user-submitted HTML; rather, use Cleaner to clean HTML.

      Returns:
      this, for chaining
      See Also:
      Element.empty(), empty()
