Hi,
I am exporting AWS WAF samples to or elasticsearch and JSON WAF return look like this :
{
"@timestamp":"2018-06-01T05:05:48.792Z",
"Headers":[
{
"Value":"xxx",
"Name":"Host"
},
{
"Value":"Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.132 Safari/537.36",
"Name":"User-Agent"
}
],
"@version":"1",
"Country":"TW",
"Method":"HEAD",
"HTTPVersion":"HTTP/1.1",
"type":"xxx",
"ClientIP":"xxx",
"URI":"/"
}
I am using json codec to parse it and everything is fine except the Headers part.
"Headers":[
{
"Name":"Host",
"Value":"54.246.206.67"
},
{
"Name":"User-Agent",
"Value":"Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.132 Safari/537.36"
}
],
The Headers key has an object into it and this object can contain multilpe values.
I would like to get all Headers objects and format them like this :
"Headers"."Host":"54.246.206.67",
"Headers"."User-Agent":"Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/63.0.3239.132 Safari/537.36",
Is someone here can help me with this ?

There is an example of something similar [here](https://discuss.elastic.co/t/solved-split-filter-question-a-k-a-flatten-json-sub-array/130481/12?u=badger).
