Hi Joel
First of all thank you very much for this intensiv reply. I still need
some time to read it all through.
Still, as I wrote Petr I have the simple need for a possibility to read
an external XML-File and extract values from certain tags like this:
Pseudo: print the value of Prozesse/cre
------------------------BEGIN XML----------------------------------
<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
<!-- Diese Datei enth�lt die Stati der xxx relevanten Prozesse -->
<!-- 0=OK, 1=Fehler/fehlend, 2=Unbekannt -->
<test1 name = "Patrick" />
<test2 name = "Scheller" />
<Prozesse>
<xxx = "1" />
<cre = "2" />
<ora = "3" />
<xxxrec = "4" />
<db_ppb = "5" />
</Prozesse>
<!-- Ende der Datei -->
-------------------------END XML-----------------------------------

Glad to hear that :-)
