Operating system: WinXP
PHP version: 4.3.4
PHP Bug Type: XML related
Bug description: XML data extraction bug
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',
'')
