XmlParser returns incorrect results

Issue #1. When error_reporting is set to E_ALL, get

Notice: Undefined variable: value in /path/to/xmlparser.php on line 148

Issue #2. XmlParser does not honor tag case (that is, <tag> and <TAG> are
understood as the same tag).
Issue #3. XmlParser ignores complete and empty tags (<tag/>, <tag></tag>).
Additionaly, a notice is issued:

Notice:  Undefined offset:  <number> in /path/to/xmlparser.php on line 119
