XPath functions: substring, substring-after with XPathNavigator.Select

[seotonseibot]

Is it possible to select substrings of selected node values with XPathNavigator.Select ?For example, what I am trying to do is:\[code\]xPath = @"//object/@data/substring-after(., '\')"var pathNavigator = xdoc.CreateNavigator();var pathNodeIterator = pathNavigator.Select(xPath);\[/code\]
