[timo dot schmid at gmail dot com]

From:             timo dot schmid at gmail dot com
Operating system: Windows XP
PHP version:      5.0.4
PHP Bug Type:     DOM XML related
Bug description:  strange return value in get_elements_by_tagname()

Description:
------------
The function seems to return a the DB-Object twice. One of the Objects is
valid, the other is missing data.

Reproduce code:
---------------
<?php
$xml = '<?xml version="1.0" encoding="UTF-8"?>
        <settings>
        <db>
        <user>root</user>
        <pw>topsecret</pw>
        <host>localhost</host>
        <type>mysql</type>
        <db>mydatabase</db>
        <fetchmode>3</fetchmode>
        <autocommit>on</autocommit>
        </db>
        </settings>';
        $dom = new DomDocument($xml);
        $root = $dom->document_element();
        print '<pre>';
        var_dump($root->get_elements_by_tagname('db'));
        print '</pre>';
?>

Expected result:
----------------
array(1) {
  [0]=>
  object(domelement)#3 (4) {
    ["type"]=>
    int(1)
    ["tagname"]=>
    string(2) "db"
    [0]=>
    int(4)
    [1]=>
    int(22694840)
  }
}
or something similar...

Actual result:
--------------
array(2) {
  [0]=>
  object(domelement)#3 (4) {
    ["type"]=>
    int(1)
    ["tagname"]=>
    string(2) "db"
    [0]=>
    int(4)
    [1]=>
    int(22694840)
  }
  [1]=>
  object(domelement)#4 (4) {
    ["type"]=>
    int(1)
    ["tagname"]=>
    string(2) "db"
    [0]=>
    int(5)
    [1]=>
    int(22693552)
  }
}
