How do I select with multiple XML level ?

Question

0.00/5 (No votes)

See more:

I have the following xml tree :

<tree>
 <subtree>
   <leave> green </leave>
   <leave> orange </leave>
   <leave> red </leave>
 </subtree>
</tree>

I need to query to pick the second leave value.

What I have tried:

I'm on a fail with :

dim color = from u in myXMl.<tree>.<subtree>.<leave>.where(function(u) u is u.elementAt(1)) select u.value

1 is for the index, the collection of nodes start at 0,
and the error thrown is "out of range" type

I really don't guess where am I faulty

and

u is u.elementAt(1)

looks too tricky, maybe wrong too

Thanks for suggestions or a new way to solve this

Solution 1

<leave>isn't the collection you want to iterate: if you want a leaf in a subtree, you query the subtree which is a collection of leaves. Try something like:

VB

from u in myXML.<tree>.<subtree>.Where(...
