XML : Can't get value with XPath in Soap XML

I have the XML and I want to find the path to price tag and code

    <soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">     <soap:Body>       <getProductDetailsResponse xmlns="http://warehouse.example.com/ws">         <getProductDetailsResult>           <productID>12345</productID>           <productName>Стакан граненый</productName>           <description>Стакан граненый. 250 мл.</description>           <price>9.95</price>           <currency>               <code>840</code>               <alpha3>USD</alpha3>               <sign>$</sign>               <name>US dollar</name>               <accuracy>2</accuracy>           </currency>           <inStock>true</inStock>         </getProductDetailsResult>       </getProductDetailsResponse>     </soap:Body>  </soap:Envelope>    

I can get the path to values if I delete namespace-xmlns="http://warehouse.example.com/ws"... The path is - /soap:Envelope/soap:Body/getProductDetailsResponse/getProductDetailsResult/price/text()

But server return it only with namespaces.

How I can get values?

Thanks in Advance
