Hey, I have a xml file as follows and I want to append the metadata which are the first few lines of the document to every event in the xml file in subsequent lines.

The xml file is [attached here](https://pastebin.com/mphwNsXr). The expected output for the first event document is [attached here](https://pastebin.com/mSdDA1xV).

I assume your xml file will have \</events\> and \</eventdata\>. If not it is not valid XML, but that can be fixed with a mutate+ gsub to append text to the message if needed.

Consume the entire XML as a single event using a file input and a multiline codec that never matches. For example

```
codec => multiline { pattern => "^Spalanzani" negate => true what => "previous" auto_flush_interval => 1 } 

```

Then you can parse the XML and split on the event field

```
xml { source => "message" target => "theXML" store_xml => true }
split { field => "[theXML][events][0][event]" }

```

Then you just have [mutate+rename](https://www.elastic.co/guide/en/logstash/current/plugins-filters-mutate.html#plugins-filters-mutate-rename) all the fields to get them where you want them.

@Badger, Thats sounds good, but how do I capture metadata details like "deploymentid" and "siteid" and duplicate it to every event document?
