Subject: Re: [xsl] Xsl stylesheet version =1 with saxon 9.x From: "Michael Kay mike@xxxxxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx> Date: Thu, 7 Mar 2019 16:27:33 -0000 |
The effect of having version="1.0" is that the stylesheet runs in "backwards compatibility mode", meaning that some constructs behave as described in XSLT 1.0 / XPath 1.0 rather than as defined in 2.0/3.0. For example, xsl:value-of applied to a sequence of several nodes displays the first in 1.0 mode, but throws an error in 2.0 / 3.0 mode. I don't think that making random changes is generally an effective strategy to problem solving; I prefer to work from the code and the failure symptoms. Even if the failure symptoms appear random, there will be some kind of pattern that gives clues. It would help, however, to try it on the latest Saxon release in case it's a known bug. Sometimes the problem is not with the XSLT code, but with the way you are running it (e.g. from the Java API). I suggest you raise a report, with as much information as possible, at saxonica.plan.io. If it's a simple stylesheet then it should be possible to put together a repro so we can try and replicate the problem; if you don't want to share your code you're welcome to send it privately.

In the past 6 months , very randomly the system is throwing a random exception , which is pointing in the direction of stylesheet xpath not returning anything .. when same file is run again, it works just fine..I could well change the version to 3.0 and fingers crossed it won't happen again. But wanted to know if there is any benefit in doing so. Clearly the dev team could not find any other issue. > > Having an xslt with version 1.0 and saxon 9.7 .. how does it treat the stylesheet ... > > > XSL-List info and archive <http://www.mulberrytech.com/xsl/xsl-list> > EasyUnsubscribe <http://lists.mulberrytech.com/unsub/xsl-list/293509> (by email <>)
