Usage

XML Example (simple.xml)

<?xml version="1.0" encoding="UTF-8"?>

<note>

<to>Tove</to>

<from>Jani</from>

<heading>Reminder</heading>

<body>Don't forget me this weekend!</body>

</note>

  1. Document parse elixir File.read!("simple.xml") |> Xmlx.parse() [note: [to: [text: "Tove"], from: [text: "Jani"], heading: [text: "Reminder"], body: [text: "Don't forget me this weekend!"]]]

  2. Find element/attribute elixir File.read!("simple.xml") |> Xmlx.parse() |> Xmlx.find(:from) [from: [text: "Jani"]]
