[TYPO3] rlmp_officeimport (General Office displayer) Problem

[christian oettinger]

Hi list,

I'm trying to install the stunning rlmp_officeimport Extension.
It works fine with the files added in the extension, but not for my file 
- which is Excel saved in 2003 XML via Open Office. Even when I open the 
xml-spreadsheet added with the extension in OpenOffice and save it 
again, it stops working (I always get an "invalid argument supplied for 
foreach" error), so I assume it is a problem of correct or not correct 
XML-code.

I understand that XML-files created by Open Office should work?
I'm not too deep into XML. Could there be a problem with line feeds? I'm 
working on OS X and see no line breaks any more with my altered file 
when opening in an editor. This does probably not mean there are none, 
but anyway.

I'm searching for four hours now, so any real light would be most welcome

Thanks in advance!!
