Ah. But I didn't say it was impossible, just impractical. I wonder about the XSLT code and processor you're using. Suppose your super incremental parallel includer/transformer (SIPIT) has received half of the included fragment, and meanwhile your XSLT processor is positioned at this template: <xsl:template match="eggs"> [...] </xslt:template> How does it deal with the fact that it cannot complete the node-set that matches the pattern? Does your processor use something like DOM's live node lists, where it can begin instantiating the template for the first few nodes in the set, and hopefully the other nodes are dynamically added as the inclusion half of SIPIT proceeds? I'm guessing processing would block until the end of the node-set is inicated, in which case you face _very_ poor parallel processing performance. Even if your processor can do this much, you have a _very_ nifty processor, and I'd like to know where you cache the source code so I can steal it. If not, I'm guessing you can't handle the above very simple, very common use-case correctly. > lot of actual XML processing will have some problems with parallel > processing, but this is an implementation issue not an XSLT language issue. Hmm. This leads me to believe we have a miscommunication. You seemed to be saying that I was wrong about the impracticality because you have a processor in your labs that can do the parallel inclusion/transforming. So do you or do you not have a SIPIT. And if you do, can I have some stock in your company? > displayed as a table (month view), as a list (day view).

My turn to go impractical, but it would be interesting if there were a Linda-like model where depending on load and capability, the transforms could be scheduled on whatever resource was best. Perhaps the server, perhaps the requestor. Perhaps even some tertium quid. "Hey, quit transforming your XML doc with _my_ CPU cycles" As Paul Prescod might note, I'd better patent the idea before Ray Ozzie gets hold of it. -- Uche Ogbuji Principal Consultant uche.ogbuji@f... +1 303 583 9900 x 101 Fourthought, Inc. http://Fourthought.com 4735 East Walnut St, Ste.
