Hi,

I am having a bit of trouble trying to find the size of a JSON array (number of elements in JSON array)  where the number of elements in this array can be different for each log message.

For example:

Logmessage1:

{transactions:{[A,B,C,D]}}

Logmessage2:

{transactions:{[A,B,C,D,E,F,G]}}

Logmessage3:

{transactions:{[A]}}

I want to get the array for the key 'transactions' and return 4 for Logmessage1, 7 for Logmessage2 and 1 for Logmessage3.

Is there anyway to do this? Any help will be appreciated.

  Sorry, the correct JSON should be the following

  Logmessage1:

  {transactions:["A","B","C","D"]}

  Logmessage2:

  {transactions:["A","B","C","D","E","F","G"]}}

  Logmessage3:

  {transactions:["A"]}

  Can this really not be possible?  I have not found the answer to this either.
