title: JSTL split array of strings
body: <p>I am receiving a string which is of type"filenmae1:format,filename2:format"so for eg it would be abc:cvs,bad:PDF.
  I want to split this string such that I can get the file names and formats.
  I don't know how long the string would be,as it would be sending numerous file names and formats or sometimes just one.
  I tried to split by the ,however I am unable to split by : to get the individual file names.
  I first set a var with the string value.then split the string using , delimiter. Now I want to loop through and split by : and get the individual file names and corresponding formats.
  Thanks for your help</p>
