How to select a boolean from a XpathNavigator

[Steve]

Hi. I have ax xpath expression which returns a true or false. I don't know
which method to use from the XPathNavigator object to get the result.
There's not a ".SelectValue("xpath expression") method. Typically, I may use
..Select or .SelectSingleNode but I'm not returning a node or set of nodes?
Maybe I shouldn't be using a XPathNavigator? Please let me know if you have
any ideas.
Thanks!

Hi Steve,

Use the XpathNavigator.Evaluate("XpathExpression") method. It will return an
Object variable, that you can convert to Boolean using CType.

HTH,

Use the method Evaluate, its return type is the generic object, you can
then cast to the type you expect e.g. a bool in C#.
