Hi All,

   Thank you for your help, and now need your suggestion as the 
below code is working and it also prints an additional value 
which is not expected, so request your help on how to avoid the 
additional value,

Code:
import std.stdio: writeln;
import asdf: parseJson;
import std.conv: to;
import std.range: takeExactly;
import std.array: split;

void main()
{
  string apidata = `{"items":
   [
     {"name":"T01","hostname":"test01","pool":"Development","type":
     [{"Value":"D,dev at dev.com,DEV"},{"Value":"000"}]},
     {"name":"T02","hostname":"test02","pool":"Quality","type":
     [{"Value":"Q,qas at qas.com,QAS"},{"Value":"100"}]},
     {"name":"T03","hostname":"test03","pool":"Production","type":
     [{"Value":"P,prd at prd.com,PRD"},{"Value":"100"}]}
   ]
}`;
  auto jv = parseJson(apidata);
  foreach(j; jv["items"].byElement()){
     foreach(i; j["type"].byElement().takeExactly(1)) {
        writeln(i["Value"].get!string("default").split(",")[1]);
     }
  }
}

Output:
dev at dev.com
qas at qas.com
prd at prd.com
[]   // additional value which is not expected

From,
