用xmerl解析xml

<result>
  <event>
    <title>My event</name>
    <artist>
      <name>Michael Jackson</name>
    </artist>
  </event>
  <event>
    <title>My event 2</name>
    <artist>
      <name>Rolling Stones</name>
    </artist>
  </event>
<result>

所以我想遍历事件,最后得到一个带有相应结果的Elixir地图.它需要与名称无关,因为事件中的字段不同.

期望的结果

[{title: “My event”,artist: [{name: “Michael Jackson”}]},{title: “My even 2t”,artist: [{name: “Rolling stones"}]}]

所以这就是我到目前为止所得到的

defmodule Test do

  require Record
  require IEx
  Record.defrecord :xmlElement,Record.extract(:xmlElement,from_lib: "xmerl/include/xmerl.hrl")
  Record.defrecord :xmlText,Record.extract(:xmlText,from_lib: "xmerl/include/xmerl.hrl")

  def run do
    {root,_} = :xmerl_scan.file("test.xml")

    event_elements = :xmerl_xpath.string('//event',root)

    # Traverse each event.
    fields = Enum.map event_elements,fn(event) ->

      # Traverse each field.
      Enum.map event,fn(field) ->
        [xmlElement(field,:name),xmlText(field,:value)]
      end
    end
  end
end

Test.run

我是Elixir的新手,我找不到xmerl的任何指南.我希望有人可以帮助我,请解释一下代码:-).
