ExecuteStreamCommand only when all info are collected

[#1]

Hi to everybody,

hope someone can help me on this.

I have a script that outputs(in json format) a list of files present in a given directory, for example it returns something like this:

{
  "name" : "2016026856",
  "type" : "directory",
  "children" : [ {
    "name" : "example.pdf",
    "type" : "file"
  }, {
    "name" : "2016026856.pdf",
    "type" : "file"
  } ]
}

After that i need to call a script that merge all files into a single PDF(of course if the file count is more than 1), the command could be simple just for example "pdfunite example.pdf 2016026856.pdf merged.pdf", however.... how can i pass to the command above all filenames found in json?

Tried splitting json, then working on fragment.count but really hard to collect all filenames...probably i'm thinking in a too complicated anner and there's a simple way to do it..

Many thanks for pointing me in the right direction.

Appreciate!
