Show Items structure in Sitecore

The following example demonstrates how to get the information about a node on the back side of a node by giving the item.ID. You also could do it easier by having the full path instead of creating an ID.
It is important to do all this inside a SecurityDisabler. You might have some nodes that are not accessible to anonymous user, if the code is running for without proper security.
