[TYPO3] Splitting a string to an array with TypoScript

[Terkild]

Hi all,

I want to be able to parse my meta-keywords assigned to my pages with 
links to my search module searching for the keyword (to find simmilar 
pages).

Is it possible thru TypoScrip to get the field, split it into an array, 
parse the elements and make them into links and then output them?

If so, how? (im not a typoscrip wizz so code exampels are more than 
welcome!)

Thanks in advance!

Kind regards
Terkild
