Hi;
Two questions. I have an XPathNavigator object where it's OuterXml property
is "<jan>231</jan>" and I am trying to write an xpath statement that will
return the "jan".
XPathNavigator nav = ...;
1) I can do nav.Evaluate("n ame(parent::*)" ); and get "month". But if I do
nav.Evaluate("n ame(self::*)"); I get "" returned. Shouldn't I get "jan"?
2) This is for code that can be passed random xpath statements. For some it
seems I need to call nav.SelectSingl eNode(xpath) and for some (the name()
example) nav.Evaluate(). Is there any way to have a single call that handles
any xpath?

Hi Dave,
Thanks for posting!
1. I tried to reproduce it, but with my code below, it is working fine. The
object returns "jan".
XmlDocument doc = new XmlDocument();
doc.LoadXml("<M onth><jan>231</jan></Month>");
XPathNavigator nav = doc.CreateNavig ator();
XPathNavigator n = nav.SelectSingl eNode("//Month/jan");
object o = n.Evaluate("nam e(self::*)");
Could you show me your code that can repro it? Thanks.
2. The SelectSingleNod e method does different things from Evaluate method.
SelectSingleNod e does an XPath query and returns another XPathNavigator, so
that you can move to another node with it.
However, Evaluate method evaluates an XPath expression and returns result.
It will be converted to an object.

Hi;
Is there a way from an XPathNavigator object to get an xpath string that
will, when used in a Select(xpath) on the underlying base/root XPathNavigator
return the same XPathNavigator?
In other words, I initially create an XPathNavigator for my entire xml
document. To get an XPathNavigator object who's root is a given node in the
original xml document, there is a unique xpath that will return that node.
The unique xpath could have,...

I have implemented in .NET 2.0 a custom XPathNavigator for Xpath filtering

A closer look has shown that there seems to be a none optimal evaluation of
attribute predicates such as . It works as expected if there is a

Hi;
If I have an XPathNavigator object and for a given xpath statement need to
know if the node exists, how should I do this? I have found for some xpath
functions it returns an empty string if the node does not exist but that is
also the result for an empty node.

Morning all from a newbie.
I have recently written an automation program (my first ever program) for testing and now I am trying to read XML data and assign the values to variables (rather than Excel). Using XPathNavigator I managed to read some of the data, but in order to do this I had to manually remove the attributes from the Parent Nodes. Going forward this isnt an option as we may be reading and running hundreds of files a day and so I...
