Subject: Re: [xsl] perfomance question about selecting from child-node From: David Carlisle <davidc@xxxxxxxxx> Date: Thu, 22 May 2003 17:23:25 +0100 |
> it is slower when i am on a specific branch/node, if i go back to t It probably is, but there is probaby a time cost in passing parameters as well. Which one wins will be highly processor specific. Compared to using keys instead of //* which can make orders of magnitude difference, this is likely to be a very small effect as you are only going .. to access th eparent and I would guess most systems optimise .. fairly heavily. If you were searching up arbitrary amounts, ancestor::*[this and that and the other] then not doing that search and passing down a parameter will probably start to win. (Unless your xsl system spots that the same search is being done repeatedly and optimises it away...).
