	Create an XML document on which to test new XPath 2.0
	functionality support.

<!--- Groovy - now let's execute some XML Path queries. --->
<cfscript>


	// Get all of the ratings that are greater than or equal to 4.5.
	results = xmlSearch(
		bookData,
		"//book/@rating[ number( . ) > 4.0 ]"
	);


	// Get the average rating of the reviews.
	results = xmlSearch(
		bookData,
		"avg( //book/@rating )"
	);


	// Get a compoud result of the Title and Author notdes. Notice
	// that we can now create divergent results in the SAME path.
	// We don't need to create two completely different paths.
	results = xmlSearch(
		bookData,
		"//book/( title, author )"
	);


	// Get all of the book's children EXCEPT for the ISBN number.
	// XPath 2.0 introduces some intesting operators like "except",
	// "every", "some", etc.
	results = xmlSearch(
		bookData,
		"//book/( * except isbn )"
	);


	// XPath 2.0 now uses sequences instead of node-sets which allow
	// for more interesting data combinations. This only gets the
	// nodes from one collection that are NOT in the other collection.
	// We're using inline branching and merging!
	results = xmlSearch(
		bookData,
		"//book/( (title, published) except (isbn, published) )"
	);


	// Get all of the ISBN numbers that use a 10-digit ISBN. XPath
	// 2.0 now supports regular exprdssion functions like matches(),
	// replace(), and tokenize() -- thought it is quicky and a
	// bit limited in patterns.
	results = xmlSearch(
		bookData,
		"//book/isbn[ matches( text(), '^\d{10}$' ) ]"
	);


	// Iterate over one collection and map it onto the resultant
	// collection. We can now iterate inline within a path.
	results = xmlSearch(
		bookData,
		"for $b in (//book) return ( $b/published )"
	);


	// We can now pass in params into our xmlSeach() calls. Notice
	// that the key, "title" is quoted - that is because XPATH is
	// case-sensitive.
	results = xmlSearch(
		bookData,
		"//book/title[ . = $title ]",
		{
			"title": "The Fountainhead"
		}
	);


	// Get the given book, no matter what the casing. FINALLY, we
	// can case-insensitive searching in XML :)
	results = xmlSearch(
		bookData,
		"//book[ upper-case( title ) = 'THE FOUNTAINHEAD' ]"
	);


	// Debug the results.
	writeDump( results );
