Hi I am getting this error while parsing XML data using logstash

[2020-04-22T16:13:54,092][ERROR][logstash.filters.ruby][main] Ruby exception occurred: undefined method `[]' for nil:NilClass [2020-04-22T16:13:54,199][ERROR][logstash.filters.ruby][main] Ruby exception occurred: undefined method ` each\_index' for {"p"=\>"1", "content"=\>"0"}:Hash

My data

```auto

```

My conf file

```auto
ruby {
	code => '
		xml = event.get("[@metadata][theXML]")
		types = xml["measType"]
		values = xml["measValue"]
		a = []
		values.each { |x|
			h = {}
			h["measObjLdn"] = x["measObjLdn"]
			x["r"].each_index { |i|
				h[types[i]["content"]] = x["r"][i]["content"]
			}
			a << h
		}
			event.set("data", a)
		'
}

```

it works when i have multiple rows in

```auto
<measType p="1">VS.PDFENoAfSessModReqFail</measType>

```

something wrong with ruby , i am not good in ruby , can someone help me.

If you have

```
        <r p="1">0</r>
        <r p="2">0</r>

```

then you will get

```
                "measObjLdn" => "Service=ims, ServiceMember=Cabinet_0_Shelf_1_Card_2_Host_0_Pool_0, Component=pdfe-stdn_imsgroup0-000",
                         "r" => [
                    [0] {
                              "p" => "1",
                        "content" => "0"
                    },
                    [1] {
                              "p" => "2",
                        "content" => "0"
                    }
                ]
            },

```

That is, r is an array. However, if you have

```
    <measValue measObjLdn="Service=ims, ServiceMember=Cabinet_0_Shelf_1_Card_2_Host_0_Pool_1, Component=pdfe-stdn_imsgroup0-001">
        <r p="1">0</r>
    </measValue>

```

then you will get

```
                "measObjLdn" => "Service=ims, ServiceMember=Cabinet_0_Shelf_1_Card_2_Host_0_Pool_1, Component=pdfe-stdn_imsgroup0-001",
                         "r" => {
                          "p" => "1",
                    "content" => "0"
                }
            },

```

where r is a hash rather than an array. A hash does not have an each\_index method.

You could set force\_array to true, and then both cases would result in an array.

I have both type of data one where

```auto
		<measValue measObjLdn="Service=ims, ServiceMember=Cabinet_0_Shelf_1_Card_2_Host_0_Pool_0, Component=pdfe-stdn_imsgroup0-000">
			<r p="1">0</r>
		</measValue>

And

<measValue measObjLdn="Service=h248, ServiceMember=Cabinet_0_Shelf_0_Card_4_Host_0_Pool_0">
				<r p="1">0</r>
				<r p="2">0</r>
				<r p="3">0</r>
				<r p="4">0</r>
				<r p="5">0</r>
				<r p="6">0</r>
			</measValue>

```

Enable 'metadata =\> true' on the rubydebug output. Look at the changes that happen when you enable force\_array. Adjust your ruby code appropriately.

Works fine Thank you so much.

Do you know the esaiset way to convert this timestamp

```auto
"2020-03-22T00:05:00+00:00\"

```

into ISO 8601.?
