Ayup.
Assuming you're using dom4j:
import org.jaxen.dom4j.XPath;
XPath xpath = new XPath( "/melty/cheese/is/great" );

There's a difference between evaluating the expression, which means
applying your xpath to a document, and 'walking the expression', which
means walking the object-tree of internal implementation objects that get
built when the string "/melty/cheese/is/great" gets parsed by the engine.
Consider it a rought 'compilation' structure for the expression itself.
Which do you really want to do?
