LINQ to XML: how do I get only direct descendants of an XElement?

Question

Dim xml = <Root>
            <Parent id="1">
              <Child>Thomas</Child>
            </Parent>
            <Parent id="2">
              <Child>Tim</Child>
              <Child>Jamie</Child>
            </Parent>
          </Root>

Dim parents = xml.Elements

In this case, children includes all the Parent elements and all of the Child elements. What's the best way to grab only the direct descendants of <Root>?

Should I write a LINQ query that selects elements where parent = <Root>? Or is there some built-in method I'm missing that can get this for me?

EDIT: I had some confusion between XElement.Elements and XElement.Descendants. As Ruben Bartelink pointed out, XElement.Elements will give me exactly what I was looking for.

Answer 1

Exec summary - you want:

xml.Elements.Select(function(element) new XElement(element.Name,element.Attributes))

First answer:

XElement.Descendants, or is it a trick question ? :P There's an example of usage of Descendants here

Revised answer, thanks Tormod -- something did feel wrong!:

Elements gives direct descendants, as you're looking for. Descendants gives the full hierarchy [as you are alleging Elements does]. (The example I linked to makes this clear. Apologies for the confusion!

So, finally, what you're looking for is (this time in VB):

Dim xml = <Root>
        <Parent id="1">
          <Child>Thomas</Child>
        </Parent>
        <Parent id="2">
          <Child>Tim</Child>
          <Child>Jamie</Child>
        </Parent>
      </Root>

REM All nodes two levels down in the hierarchy
Dim level2Nodes = xml.Elements.SelectMany(function(element) element.Elements)
level2Nodes.Dump

REM All Child nodes, no matter where they are:
Dim children = xml.Descendants("Child")

Each of which will yield you the 3 ``` elements for different reasons as covered in the REMs.

(Paste the above directly into LINQPad in VB statement mode)

I now see what might be confusing you - when you use Elements and look at it in a visualiser, you are still seeing the children:-

Dim parents = xml.Elements

If you only want the actual names, you can use something like:

Dim parentNames = xml.Elements.Select(function(element) element.Name)

Note that in each of these cases, you are getting two results.

If you really want to strip out the chidren, you want:

Dim parentElements = xml.Elements.Select(function(element) new XElement(element.Name,element.Attributes))

Can you extend your question to show what you're really looking for?
