Extract or set the contents of a leaf XML node
Some types of XML nodes have no children nodes, but are leaf nodes and
simply contain text. Examples are XMLTextMode, XMLProcessingInstruction.
This function provides access to their raw contents.
This has been extended to operate recursivel on arbitrary XML nodes
that contain a single text node.
