// Using DOM to fix sloppy HTML.

function tidyHTML($buffer)

{

  // load our document into a DOM object

  $dom = @DOMDocument::loadHTML($buffer);

  // we want nice output

  $dom->formatOutput = true;

  return($dom->saveHTML());

}



// start output buffering, using our nice

// callback funtion to format the output.

ob_start("tidyHTML");



?>

<html>

<p>It's like comparing apples to oranges.

</html>

<?php



// this will be called implicitly, but we'll

// call it manually to illustrate the point.

ob_end_flush();



?>



The above code takes out sloppy HTML:

 <html>

 <p>It's like comparing apples to oranges.

 </html>



And cleans it up to the following:

 <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN" "http://www.w3.org/TR/REC-html40/loose.dtd">

 <html><body><p>It's like comparing apples to oranges.

 </p></body></html>
