I'm trying to parsing xml file using multiline, and inside the main tag(from mutiline pattern) I want another tag to add to an array

Issue --\> I'm not able to get \<INV\_HW\_STANDARD\_MODULES\> into an array and later I can use ruby on that for other processing.

Sample xml example:

logstash.conf:  
input {  
file  
{  
path =\> "/usr/local/src/files/Physical\_Inventory.xml"  
start\_position =\> "beginning"  
sincedb\_path =\> "/dev/null"  
codec =\> multiline  
{  
pattern =\> "^\s+\</INV\_NES\>"  
negate =\> true  
what =\> previous  
}  
}  
}

filter {  
#Extract the uniqueCollectionId from the file name  
grok {  
match =\> {"path" =\> "%{GREEDYDATA}/%{NUMBER:uniqueCollectionId}-%{GREEDYDATA}Physical\_Inventory.xml"}  
}

```
xml 
{
	source => "message"
    target => "xml_content"
    xpath => ["//INV_NETWORKS//INV_SITES//INV_NES//INV_HW_STANDARD_MODULES", "hardwareI"]  
}

split {
    add_field => {"Hardware" => "%{[xml_content][INV_HW_STANDARD_MODULES]}"}
}

#Add field platform, its same for all Mini-Link nodes
mutate {
    add_field => { "platform" => "Mini-Link"}
    add_field => { "isValidated" => false}
}

#Remove all unwanted fileds
mutate {
    remove_field => ["path", "message", "host", "@version"]
}

```

}

output {  
stdout {  
codec =\> rubydebug  
}  
}

I'm not able to get \<INV\_HW\_STANDARD\_MODULES\> into an array and later I can use ruby on that for other processing.

Comment out all your filters and show us the result of your `stdout { codec => rubydebug }` output so we can see that the multiline codec is doing the right thing. I think your problems start there.
