I tried mutating the index inside the elastic stack to avail.

I'm thinking your mutate conversion syntax is incorrect and possibly the field names. Looking at the documentation, try this syntax:

```
mutate {
  convert => {
    "[Info][0][RunDate] => "date"
    "[Info][1][ProcessingTime] => "float"
  }
}

```

I mention the field name's possibly being incorrect because you specify the target as being `xml_content`. This should change the field values to `xml_content.Info.0.RunDate` and `xml_content.Info.1.ProcessingTime`. If you have an output of what the data looks like from Kibana or the query results directly from Elasticsearch, we would know for sure.
