convert dom4j.Document to net.sf.saxon.om.NodeInfo

I'd like to evaluate a xpath 2.0 type expression some xml info 
that I have as a dom4j.Document object.

Right now I'm dumping the dom4j.Document to a String 
using asXml() and then reparsing it.  

Is there a simple way to convert the dom4j.Document to 
a net.sf.saxon.om.NodeInfo?

Thanks.
