Interesting; I'm not entirely sure that I clearly understand what you're doing and what value you're trying to get from the rule engine here, which might somewhat help to pick an approach.

However, then I begin to wonder if you're going to get a lot of value out of the rule engine that you won't get out of Java and XPath already. You may, if you have a lot of little rules to run on a large XML document, and/or need to change them regularly, but ... curious. Either way, I hope you report back on your experiences, this use of Drools would be novel to me at least. - Geoffrey Martyn > > <http://www.greenhatconsulting.com/><http://www.greenhatconsulting.com> > > *Martyn Bedford* > > *Head of Solutions Practice* > > *Green Hat* > 107-111 Fleet Street > London > EC4A 2AB > > Tel: +44 20 7936 9303 > Fax: +44 (0) 20 7936 9243 > Mobile: 0777 585 2584 > > *www.greenhatconsulting.com* <http://www.greenhatconsulting.com> > > <http://www.greenhatconsulting.com/emailfooter/index.html><http://www.greenhatconsulting.com/emailfooter/index.html><http://www.greenhatconsulting.com/emailfooter/index.html><http://www.greenhatconsulting.com/emailfooter/index.html> > > Registered in England and Wales as company number 3395844 and having its > registered office at Lynton House, 7-12 Tavistock Square, London, WC1H 9LY. > The information in this internet E-mail is confidential and is intended > solely for the addressee.
