xml parser for elm

First bring XML into Elm as a `Value`. Once imported as a Value, you can then either query the values with `Xml.Query`.

Or you can turn it back to a string using `Xml.Encode.encode`. Or pull it apart using `Xml.Encode.Value`.

In order to turn an `Xml.Value` into a record, you probably want `Xml.Query`, paired with `Result.map`.

```elm

import Xml exposing (Value)

import Xml.Encode exposing (null)

import Xml.Decode exposing (decode)

import Xml.Query exposing (tags)

decodedXml : Value

decodedXml = 

	"""

	noah

	50

	josh

	57

	"""

		|> decode

		|> Result.toMaybe

		|> Maybe.withDefault null

type alias Person = 

	{ name: String

	, age: Int

	}

person : Value -> Result String Person

person value =

    Result.map2

        (\name age ->

            { name = name

            , age = age

            }

        )

        (tag "name" string value)

        (tag "age" int value)

people : List Person

people =

    tags "person" decodedXml

        |> collect person

```
