Re: [xsl] Performance degraded with grouping and sorting.

RE: [xsl] Performance degraded with grouping and sorting. | Re: [xsl] Performance degraded with grouping and sorting.
Hi All,

As Pieter (our PM for the Saxon.NET project) has pointed out the SF.net 
site is more up to date with the latest bits than the projects main 
site.  Unfortunately this is my own fault as a combination of the 
XMLDevCon (and preperations for it - see 
http://www.sellsbrothers.com/conference - I have pics and reports to 
blog as soon as a free moment opens up and will let you all know when 
there live) coupled with a new protocol I am working on and an outline 
for another project has slowed down my maintenance of the main project 
site.  I have been keeping the builds up to date and Pieter has been 
posting them regularly. I am currently working on an extension library 
that encapsulates the functionality of Saxon.NET and System.Xml and 
exposes an API that allows for only one imported namespace to take any 
XML/XSL source as input (XmlDocument(DOM), file, stream, etc...) and 
produce any desired output (string, XmlDocument, file, stream, etc...).  
This will hopefully simplify the coding process as well as the required 
imports to successfully perform a transformation while using a similar 
API to that contained in System.Xml.

Before the weekend is over the site WILL be updated and I will 
definitely have more time to refocus my efforts into producing more 
capability and extensibility into the code base that more directly 
corrolates with that of System.Xml.  I have also heard rumor (well, more 
than a rumor... I've actually had a chance to play with it a bit) from 
Pieter that he has in the works a pretty sweet sample app for testing 
stylesheets.  With that said my guess is that over the coming weeks you 
will be seeing a lot more action from the Saxon.NET project as a whole.

Best regards,

<M:D/>
