body: <p>I have this XML</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xmlns:xsd="http://www.w3.org/2001/XMLSchema"&gt;
    &lt;soap:Body&gt;
      &lt;GetSKUsPriceAndStockResponse xmlns="http://tempuri.org/"&gt;
        &lt;GetSKUsPriceAndStockResult&gt;
          &lt;RequestStatus&gt;
            &lt;DateTime&gt;2/28/2012 5:28:05 PM&lt;/DateTime&gt;
            &lt;Message&gt;S200&lt;/Message&gt;
          &lt;/RequestStatus&gt;
          &lt;SKUsDetails&gt;
            &lt;SKUDetails&gt;
              &lt;SKU&gt;N82E16834230265&lt;/SKU&gt;
              &lt;Model&gt;X54C-NS92&lt;/Model&gt;
              &lt;Stock&gt;true&lt;/Stock&gt;
              &lt;Domain&gt;newegg.com&lt;/Domain&gt;
              &lt;SalePrice&gt;439.99&lt;/SalePrice&gt;
              &lt;ShippingCharge&gt;0.00&lt;/ShippingCharge&gt;
              &lt;Currency&gt;USD&lt;/Currency&gt;
            &lt;/SKUDetails&gt;
          &lt;/SKUsDetails&gt;
        &lt;/GetSKUsPriceAndStockResult&gt;
      &lt;/GetSKUsPriceAndStockResponse&gt;
    &lt;/soap:Body&gt;
  &lt;/soap:Envelope&gt;
  </code></pre>
  
  <p>How can I read <code>&lt;SKUDetails&gt;</code> Node using XPath?. What will be XNamespace for above XML?</p>
