	var $dtattr;		function MiniXMLElementDocType ($attr)	{		$this->MiniXMLElement('DOCTYPE');		$this->dtattr = $attr;	}	function toString ($depth)	{		if ($depth == MINIXML_NOWHITESPACES)		{			return $this->toStringNoWhiteSpaces();		} else {			return $this->toStringWithWhiteSpaces($depth);		}	}				function toStringWithWhiteSpaces ($depth=0)	{
		$spaces = $this->_spaceStr($depth);				$retString = "$spaces<!DOCTYPE " . $this->dtattr . " [\n";				if (! $this->xnumChildren)		{			$retString .= "]>\n";			return $retString;		}				$nextDepth = $depth + 1;				for ( $i=0; $i < $this->xnumChildren; $i++)		{						$retString .= $this->xchildren[$i]->toStringWithWhiteSpaces($nextDepth);					}				$retString .= "\n$spaces]>\n";				return $retString;	}

	function toStringNoWhiteSpaces ()	{			$retString = "<!DOCTYPE " . $this->dtattr . " [ ";				if (! $this->xnumChildren)		{			$retString .= "]>\n";			return $retString;		}				for ( $i=0; $i < $this->xnumChildren; $i++)		{						$retString .= $this->xchildren[$i]->toStringNoWhiteSpaces();					}				$retString .= " ]>\n";				return $retString;	}
