XML representation of controls_for_each block

<xml xmlns="http://www.w3.org/1999/xhtml">
  <block type="controls_for_each">
    <field name="VAR">item</field>
    <value name="LIST">
      <block type="variables_get">
        <field name="VAR">variable</field>
      </block>
    </value>
  </block>
</xml>

{
  "src_ip": "192.168.1.5",
  "dst_ip": "8.8.8.8",
  "remote_ip": "1.2.3.4",
  "username": "administrator"
}
