Most things are roughly implemented but the devil is in the details. Controlling output is painful (through xsl:output, disable-output-escaping and friends) and other things don't work exactely as expected, leading to some teeth gnashing. There are also a few bugs in the current release. However it is moving fast and I think that it'll be stable soon enough. The biggest problem imho that might not be solved too soon is that it's string-in string-out, no support for SAX (from the Perl interface). The performance is getting much better too, though I still get better results piping through Saxon (haven't tried this in mod_perl though). -- robin b.

Sablotron from http://www.gingerall.com/ - all it lacks is xsl:number, as far as I know. AxKit has full support for XSLT transformations via Sablotron. However perl users interested in server side transformations might also be interested in XPathScript.

RE: [OT now] Re: Template techniques
Has anybody run into any Perl libraries that do XSLT transformations that are usuable? Last I looked, there was no library that implemented the spec or provided a useful API.

Re: [OT now] Re: Template techniques
We have done a comparison between Mason and Template Toolkit (both 1.x and 2.0). We ran several tests comparing cached and uncached components. For the tt tests, we wrote our own caching code against mysql as well as BerkeleyDB. What we discovered was that Mason is faster than tt 1.0 both cached and uncached. The big win is when moving to tt 2.0 as it is much faster. I also prefer the tt style of doing things since it is so flexible. We are going with the mysql cache - in our tests it was faster, but I know others who said BDB blew mysql away - it also fit our network architecture well. For what it's worth...

Re: [OT now] Re: Template techniques
I'm just using XML on the backend for content management and as a way to standardize what I recieve from partners and content folks, then storing parsed content in a database from which I output text, HTML, and/or XML. XML::Parser suits quite fine for the above. So, Perl has plenty of XML support, imo. I've taken a look at what Matt is up to and I'm intrigued, but don't have a need for it as yet. Joshua, what is the itch that you are scratching if you care to opine?

The more (and the sooner :-) packages support XML easily and natively, the better. I'm still an XML newbie, so all this recent perl XML development is very exciting for me! -- Drew Taylor Vialogix Communications, Inc. 501 N.
