Good morning everyone,
Hmmm interesting. I set up the same stylesheet xsl:if
test for the function and get Michael's true result.
So I know that extension functions for Saxon are there
butttt...
The xsl:when test still returns the same results which
makes me think maybe my logic is screwed up? It's
simple test logic so not sure why it is behaving the
way it is...
Logic in <ans3> below:
When saxon:evaluate-node available, use it.
When dyn:evaluate available, use it.
Otherwise output error.
(
I guess the logic could be better like below so if
both fucntions are available, it does things better,
but still original should work...
When saxon:evaluate-node available, use it.
Otherwise
When dyn:evaluate available, use it.
Otherwise output error.
)

A possible explanation is that you are running with
extension functions
disabled: how is Saxon being invoked? Another
possibility is that you aren't
actually running Saxon at all - add a call on
system-property('xsl:vendor')
to the stylesheet to check.

Hey,
What namespace URI is bound to the prefix
"saxon"
I bind http://saxon.sf.net/ to saxon
...
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:dyn="http://exslt.org/dynamic";

Which version of
Saxon are you using?
"Saxon 8.3 from Saxonica"
Thanks,
Arian

Subject: [xsl] function-available() problem
while
using Saxon
Hello all,
One last question for the day hopefully.
I deciding since I might be using FOP(which
uses
Xalan) and at some points be using Saxon to
see
whats
wrong in my .fo output, that I would see which
extension function is available and use it
accordingly.
Xalan checks to see if saxon:evaluate-node is
available 1st and fails. Then dyn:evaluate is
available and correctly used.
In Saxon, it checks to see if
saxon:evaluate-node
is
available and FAILS?, then I believe tries to
USE
dyn:evaluate and errors? It shouldn't even get
to
the
point of using dyn:evaluate since it isn't
available
right? (i am prob doing something very wrong).
I
should mention I do put saxon: and dyn:
namespaces
in
the top of the xsl I am using, so thats not
the
problem.
XP0003: XPath syntax error at char 18 on line
200
in
{dyn:evaluate($exp)}:
Cannot find a matching 1-argument function
named
{http://exslt.org/dynamic}evaluate()
###part that selects what function to use
<xsl:choose>
<xsl:when
test="function-available('saxon:evaluate-node')"><xsl:for-each
select="document(@href)/Document">
<xsl:apply-templates
select="saxon:evaluate-node($exp)"/>
</xsl:for-each></xsl:when>
<xsl:when
test="function-available('dyn:evaluate')"><xsl:for-each
select="document(@href)/Document">
<xsl:apply-templates
select="dyn:evaluate($exp)"/>
</xsl:for-each></xsl:when>
<xsl:otherwise><xsl:message>EXSLT:EVALUATE()
OR
SAXON:EVALUATE-NODE() NOT FOUND IN YOUR XSL
PROCESSOR</xsl:message></xsl:otherwise>
</xsl:choose>
Thanx again to the xsl list and Michael Kay
Unrelated Note if someone notices I could use
a
simpler template for Saxon: I dont use that
simple
template like below because if Xalan is being
used, it
will not like the 'function call as a step in
the
xpath' as it parses beforehand, so i keep it
as
is.
<xsl:apply-templates
select="document(@href)/Document/saxon:evaluate-node(current()
/@nodes))"/>
