```elixir

def deps do

  [{:xmlx, "~> 0.0.1"}]

```
  1. Ensure xmlx is started before your application:
```elixir

  [applications: [:xmlx]]

end

```

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) or elixir File.read!("simple.xml") |> Xmlx.parse() |> Xmlx.find("from") [from: [text: "Jani"]]

WSDL Example (simple.wsdl)
