Can I get some help parsing the "my_cool_id" from the following xml using XDocument?

<?xml version="1.0" encoding="UTF-8"?>
<xfdf xmlns="http://ns.adobe.com/xfdf/" xml:space="preserve">
  <fields>
    <field name="field_name_1">
      <value>12345</value>
    </field>
    <field name="my_cool_id">
      <value>12345</value>
    </field>
    <field name="field_name_2">
      <value>12345</value>
    </field>
    <field name="field_name_3">
      <value>12345</value>
    </field>
  </fields>
</xfdf>
