Match each node in the tree with a line in the XML document above (draw a tree with the same layout as the given XMLTree where each node has the line number corresponding to that node).

Draw the node(s) in the tree that correspond to line 3 in the XML document.

Draw the node(s) in the tree that correspond to line 8 in the XML document.

What line(s) in the XML document correspond to the node?

Consider the text node An American in Paris in the XML tree above.

Draw the nodes on a path from the root of the tree to this node.

Suppose we modified the XML document above so that both the and the tags have an attribute born whose value is the date of birth, i.e.,

3 4	George Gershwin Leonard Bernstein

Draw the nodes in the XMLTree that would have to be modified to include this new information.

Now suppose we wanted to change the tag in the XML document above so that the date is not an attribute of the tag but instead atext child of the tag node.

Rewrite line 5 in the XML document above to show the result of this change.

Draw the nodes in the XMLTree that would have to be modified to reflect this change in the XML document.

Draw the complete XMLTree corresponding to this document.

A city is logically inside a state. So, change the structure of the XML document to put the element inside the element. What essentially arbitrary decision did you make when doing this? Redraw the part of the XMLTree that is changed by this modification, taking care to match the document with respect to the decision just mentioned.
