Puh.. I don't have any experience with such big updates. Maybe just try 4.0 
and then 4.2
For TYPO3 4.2 you need at least PHP 5.2.

I think xml_parser_create() is part of SimpleXML library  - so you have to 
install this PHP extension. As there are still calls to this function in 
newer TYPO3 versions, it would be necessary in every case, to solve this 
problem, if you want to upgrade to any version.
