parsestringarrayidx

Prototype: parsestringarrayidx(array, input, comment, split, maxentries, maxbytes)

Return type: int

Description: Populates the two-dimensional array array with up to maxentries fields from the first maxbytes bytes of the string input.

This function mirrors the exact behavior of readstringarrayidx(), but reads data from a variable instead of a file. By making data readable from a variable, data driven policies can be kept inline.

Arguments:

• array : Array identifier to populate, in the range [a-zA-Z0-9_$(){}\[\].:]+
• input : A string to parse for input data, in the range "?(/.*)
• comment : Regex matching comments, in the range .*
• split : Regex to split data, in the range .*
• maxentries : Maximum number of entries to read, in the range 0,99999999999
• maxbytes : Maximum bytes to read, in the range 0,99999999999
  

Example:

    bundle agent test(f) 
    {
    vars:
      # Define data inline for convenience
      "table"   string => "one: a
                           two: b
                         three: c";
