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

import Xml exposing (Value)
import Xml.Encode exposing (null)
import Xml.Decode exposing (decode)
import Xml.Query exposing (tags)

decodedXml : Value
decodedXml = 
    <age max="100">50</age>
    <age max="100">57</age>
        |> decode
        |> Result.toMaybe
        |> Maybe.withDefault null

type alias Person = 
    { name: String
    , age: Int

person : Value -> Result String Person
person value =
        (\name age ->
            { name = name
            , age = age
        (tag "name" string value)
        (tag "age" int value)

people : List Person
people =
    tags "person" decodedXml
        |> collect person
