Stewart,

One thing to note. Answer 2 and 3 don't match the case for columns "name" and "componentname" as declared in the example code. Since I know little of XML, I took a stab at this question by eliminating those 2 answers first based solely on the columns not matching and then tried to figure it out. I got lucky and answered correctly.

Not sure how many others would narrow down their response this way but I thought I would bring it to your attention anyways.
