xpath

My code doesn't return the node

XmlDocument xml = new XmlDocument();
xml.InnerXml = text;

XmlNode node_ =  xml.SelectSingleNode(node);
return node_.InnerText; // node_ = null !!!!!!!!!!!!!!!!!!!

I'm pretty sure my XML and Xpath are correct

My Xpath : /ItemLookupResponse/OperationRequest/RequestId'

My XML :

<?xml version="1.0"?>
<ItemLookupResponse xmlns="http://webservices.amazon.com/AWSECommerceService/2005-10-05">
<OperationRequest>
<RequestId>xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxxx</RequestId>
.......(the rest of the xml is irrelevant)..........

The node my XPath returns is always null for some reason. Can someone help?

Dynamic Type to do away with Reflection

as seen on West-Wind - Search for 'West-Wind'
The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions… >>> More
