I thought that even though it might be an awkward way to do it, the example that doesn't work is walking through each node and then reading to the next chapter element. So why would this only get the first value but not eventually the second, even if in a non efficient manner? Seems like it has something to do with cursor position but I don't know exactly what.
How I see it is that it goes to the first node, and then goes to the chapter element and gets the value, and then the Read method would read the next node after the first chapter element that readtofollowing("chapter") took the cursor to, and then go to the second chapter element following the node that it is currently on, and then walk through any other nodes remaining and fail on an attempt of readtofollowing("chapter") because there would be no more chapter elements left.
So I am missing something very fundamental and important.
How I vision this is that in the first iteration of the while, the Read method takes me to the first node. Then the readtofollowing method within the while loop takes me to the chapters element after the first node. Then, on second iteration of the while loop, the Read method takes me to the next node after the first chapter element. So if the next node did not have a second chapter element, wouldn't it then go from the node it is at and find the second chapter element in the "novels" element through it's call to reaftofollowing within the while loop?
Your answer makes sense and I think I already know the answer to the second question I am asking, but I would like confirmation. Thanks.
