    &lt;/Valute&gt;
   &lt;Valute ID=&quot;944&quot;&gt;
     &lt;CharCode&gt;AZN&lt;/CharCode&gt; 
     &lt;Nominal&gt;1&lt;/Nominal&gt; 
     &lt;Name&gt;Манати Озарбой&amp;#1207;он&lt;/Name&gt; 
     &lt;Value&gt;6,0677&lt;/Value&gt; 
    &lt;/Valute&gt;
   &lt;Valute ID=&quot;826&quot;&gt;
     &lt;CharCode&gt;GBP&lt;/CharCode&gt; 
     &lt;Nominal&gt;1&lt;/Nominal&gt; 
     &lt;Name&gt;Фунт-стерлинги Ингилистон&lt;/Name&gt; 
     &lt;Value&gt;7,3156&lt;/Value&gt; 
     &lt;/Valute&gt;
  ...
