I think that you mean by "parse" something different from what I mean. What exactly are you trying to accomplish?
by parsing i mean looping and outping each of the array value.
oops i should have showed a example,
i want the array to be outputted in the following format:
[content] hello world
Heading1 will be array which contain a array inside it storing the information about that heading, there can be more than one Heading1 arrays that why i need a loop.
