XPath (XML Path Language) is a language for selecting nodes
from an XML document. In addition, XPath may be used to
compute values (strings, numbers, or boolean values) from
the content of an XML document. XPath was defined by the
World Wide Web Consortium, W3C.
The XPath language is based on a tree representation of the
XML document, and provides the ability to navigate around
the tree, selecting nodes by a variety of criteria. In
popular use (though not in the official specification), an
XPath expression is often referred to simply as an XPath.

What do you mean by query string?
a web application needs to be created to accept the product name and quantity of a toy from a customer. After the customer has entered the product name the application needs to display the discounted price of the product to the customer (company is offering 35% discount on all products). The application should allow the customer to select the product name from a list box. and also while i'm data binding to a label with custom data binding with some declarations : "The Discounted Price is "+((System.Convert.todouble(lblprodprice.text)*(system.convert.todouble(txtqty.text)) - ((System.convert.todouble(lblprodprice.text)*(system.convert.todouble(txtqty.text)*0.35)). Where i need to give this declaration in asp.net 2.0.
