Funktion nicht einwandfrei

[Dorftrottel]

Hallo,

ich schreibe aus einer Datenbank eine schöne XML Datei leider ist diese nicht konform mit den XML Standarts.
Weil der Anfang

<?xml version="1.0" standalone="yes"?>  
<datenbank>

als auch das Ende
</datenbank>
sowie zwischen den Einträgen ein Enter ist.

Die Funktion habe ich entdeckt (siehe unten) auch die Stelle wo scheinbar alle Daten eingefügt werden $xml_sdr_tmp_html aber wo kann ich jetzt den XML Header und Footer einfügen? Und wie entferne ich das Enter zwischen den Datensätzten.
