how can you use the function for flexforms?
As I got it running meanwhile I see no values in the reuslt.
there only is the tag-structure , and so there are some tags on the same 
level, only the last tag (or better: structure in tag) is shown in the 
result.

my problem was another: xml2array() expects to have the whole document 
in one tag.
with the leading
<f:layout name="Content" />
the scan stops as it decided the end of document, but noticed further data.
solution: xml2array('<wrap>' . $content . '</wrap>');

  as said above: no parallel tags, no values, no attributes => no 
possible usage
I think I will use xml2tree(), but that might be to much data. as it 
uses a lot of additional entries in the array I can't assign to anything
(a lot of empty entries in subnodes['values'])
