與XPath的單值解析XML返回空字符串

我想在這個XML得到這個值B006PF20EI與XPath的單值解析XML返回空字符串

<ItemSearchResponse xmlns="http://webservices.amazon.com/AWSECommerceService/2011-08-01"> 
    <OperationRequest>...</OperationRequest> 
    <Items> 
     <Request>...</Request> 
     <TotalResults>8</TotalResults> 
     <TotalPages>1</TotalPages> 
     <MoreSearchResultsUrl>...</MoreSearchResultsUrl> 
     <Item> 
      <ASIN>B006PF20EI</ASIN>

我使用XPath的，像這樣

public String parseXml(String xmlString){ 

    DocumentBuilderFactory domFactory = DocumentBuilderFactory.newInstance(); 
    try { 

     DocumentBuilder builder = domFactory.newDocumentBuilder(); 
     Document dDoc = builder.parse(new InputSource(new StringReader(xmlString))); 

     XPath xPath = XPathFactory.newInstance().newXPath(); 
     //Node node = (Node) xPath.evaluate("/Items/Item/ASIN", dDoc, XPathConstants.NODE); 
     //System.out.println(node.getNodeValue()); 
     String value = xPath.evaluate("/ItemSearchResponse/resp/status", dDoc); 
     return value; 
    } catch (Exception e) { 
     Log.e("MYAPP", "exception", e); 
     return null; 
    } 
}

但它看起來像該方法只是返回一個emptry字符串

使用良好的路徑：

/ItemSearchResponse/Items/Item/ASIN
