XML to array

[fk]

ich bin mal so nett aus meinem bastelfundus:

/**
* Diese Klasse erstellt ein array aus einem XML Datenstrom

* Ausgabe:
* [TAG1][TAG2][<ATTRIBUTES>] = Attribute des Tags(array)
* [TAG1][TAG2][<CDATA>] = Text
* oder XPATH
* [TAG1.TAG2.<ATTRIBUTES>] = Attribute des Tags(array)
* [TAG1.TAG2.<CDATA>] = Text
* oder gemischt
