Description:
------------
Using Expat XML functions.

The character data handler will occasionally return only a first part of data. It will be immediately called again and return the rest.

This bug only occurred around the 20th and 40th records in a dataset containing about 80. This occurred with multiple data-files where the consistency between records has been verified.

Sample:
<logentry><date>2004.01.21</date><time>01:33:38</time><ip>127.0.0.1</ip><querystring>INSERT INTO residents VALUES (55, "Chambers", "Harveasha", '0', '0', '', '216', '')</querystring><position>backup.php/3</position></logentry>


Reproduce code:
---------------
// gets the last label recorded
function getlabel()
{
	global $stack;

	$tagname = array_pop($stack);
	array_push($stack, $tagname);

	return $tagname;
}

// character-data handler
function havedata($parser, $data)
{
	global $recorddata;

	$data = trim($data);		
	if(strlen($data) == 0)
		return;

	$recorddata[getlabel()] = $data;
}


Expected result:
----------------
INSERT INTO residents VALUES (54, "Lewis", "Theresa", '0', '0', '', '215', '')
