.plurals_from_xml(path) ⇒ Object

Extracts plural definitions from xml to a hash

For example:

<plurals name="user_count">
    <item quantity="one">1 user</item>
    <item quantity="many">%d users</item>
</plurals>

Is returned as:

{ "user_count" => { "one"  => "1 user",
                    "many" => "%d users" } }
