Hello every one
I am stuck in a problem that how to pass QueryString (Request.QueryString["RefId"]) to xpath into XML
following is the code of my

XmlNode newParent = doc.SelectSingleNode("/LinkInformation/ScreensToSupport/ScreenToSupport/SupportItems/ScreenSupportItem[RefId=@'+(Request.QueryString["RefId"])+]");

I have to pass Query String RefId in the doc.SelectSingleNode
Please any can tell me.
I will very thankful to you

Life might be simpler for you if you split that one line into a couple of lines. This way you can check what is in the xpath variable by debugging the code - if this isn't what you want then you can change the line ot get it to work.

You include the '@' in your xPath - if this is because RefId is an attribute then it should be '@RefId'. If you're just getting it confused with the C# string literal character then you don't need it.

string refId = Request.QueryString["RefId"];

string xpath = "/LinkInformation/.../ScreenToSupportItem[RefId='" + refId + "']";

XmlNode newParent = doc.selectSingleNode(xpath);
