Hi Andrew, > Examples are almost non-existant and their mailing > list has been completely unresponsive. Which list are you sending messages to? I've tried to get the word out that the official support list for Saxon.NET is 'saxondotnet-help'. Unfortunately not everyone reads the blog entries on the project weblog (http://weblog.saxondotnet.org) and because I am slammed at the moment working on a project that has my time booked until the end of the month I havent had a chance to get the word out. Unfortunately for some reason SF.net doesnt allow you to delete mailing lists. As such there are several lists there that are inactive. As I mentioned my time is limited at the moment, but if you can post a message to the saxondotnet-help list I will take a look at this as soon as I have a chance and respond back via that mechanism. If there are others who have similar needs please visit > http://lists.sourceforge.net/lists/listinfo/saxondotnet-help Actually, in checking the archives I'm noticing a post from you (Andrew) from the 29th of July to saxondotnet-help. This is the first I've seen this... That worries me. I will check and make sure there isn't an error in the list-admin email address. If you could post your message again I can use this as a test. If you don't get a response within 12 hours or so then send a message directly to me and I will get to the bottom of the problem. Please note also that as per my last post to the project weblog > http://weblog.saxondotnet.org/archives/2005/08/saxonnet_85_rc1_1.html you can gain access to the Saxon.NET 8.5 bits via CVS. I haven't had the time necessary to run this release through the proper set of tests and as such have not packaged it as an official release. However, it may be worth your while to checkout the Saxon.NET-Latest module from the CVS repository on SF > https://sourceforge.net/cvs/?group_id=112449 While there is no guarantee this will solve your problem it might be worth the effort to give it a try. See ya over on saxondotnet-help (hopefully :) Cheers :) On 8/11/05, Andrew Sharpe <andrewrwsharpe@xxxxxxxxx> wrote: > Thanks very much Dr. Kay.
