I would really appreciate if someone has got a simple approach to the following problem: 
I just want to import an xml file and pickout the elements with the same name an put them into an 
textframe ,then an other element with an different name into an other text frame ,an so on 
There must be an simple way to do this but as far as i am with my script it`s just replacing 
the textframe with an other textframe .An not putting the new element into the the textframe on an 
new line 
I know there's something real simple that I'm missing. Just can't figure out what it is. 

here`s the xml an the script i`m using 
(*<?xml version="1.0" encoding="UTF-8"?> 
<artikel> 
		<artnr>100.01</artnr>artn 01 
		<artnr>100.02</artnr>artn 02 
		<artnr>100.03</artnr>artn 03 
		<artnr>100.04</artnr>artn 04 
		<artnr>100.05</artnr>artn 05
