XmlSchema

🧼 (BAR OF SOAP)

🧽 (MOP)

XML Parser based on Ecto schemas

Parses XML documents directly into Ecto.Schema but with additional layer of DSL to describe XML structure. All features from Ecto.Schema can be used.

Sample

defmodule Embed1 do
  use XmlSchema

  xml do
    xml_tag :EventHorizon, :string
    xml_one :Single, Single
  end
end

(Single is defined in tests/support/single.ex)

All XmlSchema instrumented modules provide xml outer declaration with inner declarations of:

• xml_tag - A terminal XML node with CDATA values
• xml_one - A tag that contains one substructure
• xml_many - A tag that contains many of the named tag

Tags unspecified are ignored.

Above parses:

<?xml encoding="utf-8" ?>
<Embed1 creator="danj">
  <EventHorizon>No Light escapes</EventHorizon>
  <Name>Bob</Name>
  <Single complete="false">
    <Name>Bob</Name>
    <Address>123 Evergreen Terrace</Address>
    <Address>Apt 123</Address>
  </Single>
</Embed1>

and results in

%Embed1{
    _attributes: %{"creator" => "danj"},
    EventHorizon: "No Light escapes",
    Single: %Single{
      _attributes: %{"complete" => "false"},
      Name: "Bob",
      Address: ["123 Evergreen Terrace", "Apt 123"]
    }
  }
