XML & C# challenge - #4

All - can someone tell me how to achieve this? Here's the background:

There are multiple <Notes> tag but only want the one inside the <Header> (see the image for a clearer illustration of this). Then I want to concatenate the two notes tag into one sentence.

For instance, the output should be:
This is the first note. This is the second note.

Thanks in advance!
