XPath
? XPath specifies path expressions that match XML data by navigating down (and occasionally up and across) the tree
? Example
? Query: /bibliography/book/author
? Like a file system path, except there can be multiple "subdirectories" with the same name
? Result: all author elements reachable from root via the path /bibliography/book/author
