How to parse XML with Tag Names having spaces in C#

I have an xml file which is having this structure :

<?xml version="1.0" encoding="utf-8" ?>
<Countries>
   <Australia>
        <LabelABN>ABN</LabelABN>
        <TextBoxLimitABN>14</TextBoxLimitABN>
        <LabelACN>ACN</LabelACN>
        <TextBoxLimitACN>14</TextBoxLimitACN>
    </Australia>
    <Pakistan>
        <LabelABN>NTN</LabelABN>
        <TextBoxLimitABN>20</TextBoxLimitABN>
        <LabelACN>BNN</LabelACN>
        <TextBoxLimitACN>22</TextBoxLimitACN>
    </Pakistan>
    <India>
        <LabelABN>NTT</LabelABN>
        <TextBoxLimitABN>18</TextBoxLimitABN>
        <LabelACN>IDP</LabelACN>
        <TextBoxLimitACN>24</TextBoxLimitACN>
    </India>

</Countries>

This structure works fine , but if i add a country named Saudi Arabia , it reds out in Visual Studio 2010 . e.g.

<?xml version="1.0" encoding="utf-8" ?>
<Countries>
   <Australia>
        <LabelABN>ABN</LabelABN>
        <TextBoxLimitABN>14</TextBoxLimitABN>
        <LabelACN>ACN</LabelACN>
        <TextBoxLimitACN>14</TextBoxLimitACN>
    </Australia>
    <Pakistan>
        <LabelABN>NTN</LabelABN>
        <TextBoxLimitABN>20</TextBoxLimitABN>
        <LabelACN>BNN</LabelACN>
        <TextBoxLimitACN>22</TextBoxLimitACN>
    </Pakistan>
    <India>
        <LabelABN>NTT</LabelABN>
        <TextBoxLimitABN>18</TextBoxLimitABN>
        <LabelACN>IDP</LabelACN>
        <TextBoxLimitACN>24</TextBoxLimitACN>
    </India>
  <Saudi Arabia>
    <LabelABN>NTT</LabelABN>
    <TextBoxLimitABN>18</TextBoxLimitABN>
    <LabelACN>IDP</LabelACN>
    <TextBoxLimitACN>24</TextBoxLimitACN>
  </Saudi Arabia>
</Countries>

This is my requirement in project to list the countries name with their specs in XML file
