Result of Transformation

PKHG · August 5th, 2008, 02:08 PM

Struggling with hello.xml, transformed by hello.xsl
this can be remarked:

Asking for the source of the result (either IE7 or FF3) the XML is shown!?
In FF3 with Firebug-plugin one may inspect elements and doing so the transformation is nicely seen.

Using Saxionb like this

Code:

c:\web\xampp\htdocs\xml\saxonb>java -classpath . -jar saxon9.jar -t -s:hello.xml hello.xsl 
java -classpath . -jar saxon9.jar -t -s:hello.xml hello.xsl 
Saxon 9.1.0.1J from Saxonica
Java version 1.6.0_07
Warning: at xsl:stylesheet on line 2 column 80 of hello.xsl:
  Running an XSLT 1.0 stylesheet with an XSLT 2.0 processor
....

Shows the HTML code too (nice!)

Where did the Warning come from? In the orginal has this line:

Code:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

replacing 1.0 by 2.o the Warning vanisches :D

IE has a plug-in to allow you to view the generated HTML, but I've forgotten where you get it from.

>Where did the Warning come from?

The W3C WG decided that because there is a very small risk that an XSLT 2.0 processor might produce different results from a 1.0 stylesheet than a 1.0 processor would produce, the processor must give you a warning if you do this. In my view, however, it's not a particularly good idea - those who know about the version differences don't need the warning, and those who don't get unnecessarily alarmed. Also, it tends to encourage people to do what you have done - change the version to 2.0 - which is far more likely to introduce minor incompatibilities if you don't know what you are doing, because in cases where there are differences, a 2.0 processor will use the version="1.0" setting as a signal to behave in a backwards-compatible way.

OK, understood.
Only one idea: the Warning is a little bit strange: couldn't it be more precise? column 80 (end of line I think) says what? Version Warning would be more understandable, wouldn't it?
Because I did not get yet other warnings, ...

Sorry, I can't see how the message could be more precise. It says it's a warning, it says where it's encountered in the source, it says that the (possible) problem is that you are running an XSLT 1.0 stylesheet using an XSLT 2.0 processor. What more is there to say (short of giving a list of all the things that could conceivably go wrong when you run a 1.0 stylesheet using a 2.0 processor)?

You are right, so sorry .... I did not read the second line, but focussed on column 80
Please forgive me. Will try to do better
