Pretty HTML snippet output

I've a snippet of HTML <div><p>text1</p></div><div><p>text1</p></div>

I want to make it pretty like this

<div>
  <p>text1</p>
</div>
<div>
  <p>text1</p>
</div>

What would be most simple way to do it? (I've looked on transform and jsoup) but not sure what would be really smart to use. Thanks!

Solution

  • jTidy could fit for this task - http://jtidy.sourceforge.net/howto.html

    public String prettyPrintHTML(String rawHTML)
{    
    Tidy tidy = new Tidy();
    tidy.setXHTML(true);
    tidy.setIndentContent(true);
    tidy.setPrintBodyOnly(true);
    tidy.setTidyMark(false);

    // HTML to DOM
    Document htmlDOM = tidy.parseDOM(new ByteArrayInputStream(rawHTML.getBytes()), null);

    // Pretty Print
    OutputStream out = new ByteArrayOutputStream();
    tidy.pprint(htmlDOM, out);

    return out.toString();
}
