A string that expresses an XPath query.
Return Value
An array of NSXMLNode objects that match the query, or an empty array if there are no matches.
Discussion
The receiver acts as the context item for the query (”.”). If you have explicitly added adjacent text nodes as children of an element, you should invoke the NSXMLElement method normalizeAdjacentTextNodesPreservingCDATA(_:) (with an argument of false) on the element before applying any XPath queries to it; this method coalesces these text nodes. The same precaution applies if you have processed a document preserving CDATA sections and these sections are adjacent to text nodes.
