Evaluate XPath expression to select a single node, nodes collection, or to evaluate other XPath expression that do not return the node-set (such as XPath functions). Type the XPath expression; write the namespace bindings required, if any; and select the appropriate selection criteria (node, node-set or other expression). MSXML selectSingleNode and selectNodes is used to get the node-set(s); and XSLT stylesheet is applied to evaluate the XPath expressions such as XPath functions, etc.
