If you just require to transform the XML data to an php array and vice versa
you will probably like:
t3lib_div::xml2array(...);
t3lib_div::array2xml(...);

If you want to access the fields within the PHP array structure one must say
that there are rarely no APIs/wrappers.

Those in tslib_pibase don't concern about the language settings lDEF and vDEF
AFAIK (correct me if im wrong)

also they are not really usable to get a repeated content element out of a
flexform XML/php structure.


In those extensions where I used Flexforms and respected language variables
I had a look at how TV get's the values for lDEF and vDEF (grep for it in TV sources)
and resemebled that for BE and FE.

Then I accessed the PHP data structure directly (print_r or debug_array is your friend)
