<P>
The methods in this class are convenience methods into the
 low-level XPath API.
 These functions tend to be a little slow, since a number of objects must be
 created for each evaluation.  A faster way is to precompile the
 XPaths using the low-level API, and then just use the XPaths
 over and over.
