Código PHP:

<?php
class tabulador{
    private $code;
    private $_tbs;
    private $tbs;
    private $cache;
    public function __construct($code){
        $this->code = $code;
    }
    public function tabular($tabkey = "\t"){
        $this->code = preg_replace('@>([\n\r\s]+)<@', '><', $this->code);
        $this->code = preg_replace('@([\n\r\t]{1,})@', '', $this->code);
        $this->code = preg_replace('@(<!doctype([^>]*)>)@i', "$1\n", $this->code);
        for($t=0;$this->cache!=$this->code;++$t){
            $this->cache=$this->code;
            $this->_tbs = str_repeat($tabkey, $t);
            $this->tbs = str_repeat($tabkey, $t+1);
            $this->code = preg_replace('@<(\w+)([^>]*)>(.*?)</\1>@', "<$1$2>\n".$this->tbs."$3\n".$this->_tbs."</$1>\n".$this->_tbs, $this->code);
        }
        //$this->code = preg_replace("@($tabkey*)<(\w+)([^>]*)/>@", "\n<$2$3/>\n", $this->code);
        $this->code = preg_replace("@[\n\r]$tabkey*[\n\r]@", "\n", $this->code);
        return trim($this->code);
    }
}
//$texto = "<span><div><input /><input /><input /><input /></div></span>";
$texto = file_get_contents("http://www.google.cl");
$tab = new tabulador($texto);
echo $tab->tabular("    ");
?>
