Hi Vino,
byElement should be used here for ASDF.
foreach(j; jv["items"].byElement)

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,d...@dev.com,DEV"},{"Value":"000"}]},
{"name":"T02","hostname":"test02","pool":"Quality","type":
[{"Value":"Q,q...@qas.com,QAS"},{"Value":"100"}]},
{"name":"T03","hostname":"test03","pool":"Production","type":
[{"Value":"P,p...@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:
d...@dev.com
q...@qas.com
p...@prd.com
[] // additional value which is not expected

The API's are different. You can't just expect one to work with
the api of the other.
Asdf is a bit more strict in that you have to specify whether you
intent to iterate a json object (with `.byKeyValue()`) or a json
array (with `.byElement()`).
Also the way you fetch values out of it is different. There is
`.get!T(default)` that requires a default value in case it is
empty (undefined), or `cast(T)field` if you assume there is a
value and want an exception throw if not.
