Can any one recommend a tutorial site or documentation on using XPATH and
SelectNodes with Tdom, i'm playing with the traversal of nodes and am not
familiar with the syntax.


one example is lets say I have this basic xpath structure

/Level1/A/a/blah/blah...
/Level1/A/b/blah/blah...
/Level1/A/c/blah/blah...
...
/Level1/B/a/blah/blah...
/Level1/B/b/blah/blah...
/Level1/B/c/blah/blah...

and what I want to do is put together a query that will return the nodes
/Level1/A/ , /Level1/B/ , etc.  I dont want leaf nodes,  just a list of the
Nodes say A, B, C, ..., (2nd level nodes)... so that I can pass this list of
nodes to a function for processing :)

I know this is a basic question and there has to be a good site that would
maybe go over this and some other basic queries too, if u can point me in
that direction too that would be great.

thanks for your time,
