hi,
I want to test the xsl provided by mukul in this thread, but i do not find
any xml file there,
in that case what i have to do, (ie what source doc i have to use) please
provide me a sample source doc
to use the style doc provided by mukul.
Regards
Eugene

Re: [xsl] Recursion performance (fibonacci numbers)
Hi,
Is your question related to the below thread? If not, you need
to go through the XSL list guidelines. You need to start a new thread when
you want to ask a new question.
Having said that, an XSL stylesheet is plain text and hence is not
executable by itself. But if you have a XSLT processor like saxon, xalan
etc, they can load your stylesheet and execute them for you. The command
to
execute under each processor is as follows:
saxon 6.5:
java com.icl.saxon.StyleSheet [options] source-doc style-doc
{param=value}... > xslt.out
xalan 2.9
java com.sun.org.apache.xalan.internal.xslt.Process -IN infile.xml -XSL
infile.xsl -OUT outfile
You would need to have the relevant jars in your classpath before you can
run your commands though.
Hope this helps.
cheers,
prakash

Hi all,
Can anybody tell me, how to execute the xsl stylesheet in the command
prompt.

Re: [xsl] Recursion performance (fibonacci numbers)
Thanks Mike. I was using the wrong namespace. With
saxon:memo-function="yes" its quite fast.

It's not linear at large values of "n" because BigInteger arithmetic
takes
longer the larger "n" becomes; but the use of a memo function certainly
solves the XSLT-level problem.
Are you sure you used the right namespace http://saxon.sf.net/ ?

Dear All,
I am running this XSLT stylesheet with Saxon b 8.6.1. This prints
1st n Fibonacci numbers, where n is supplied as a stylesheet
parameter.
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:xs="http://www.w3.org/2001/XMLSchema";
xmlns:myfunc="http://dummy";
version="2.0">
<xsl:output method="text" />
<xsl:param name="n" />
<xsl:template match="/">
<xsl:for-each select="1 to $n">
<xsl:value-of select="myfunc:fibonacci(position())"
/><xsl:text> </xsl:text>
</xsl:for-each>
</xsl:template>
<xsl:function name="myfunc:fibonacci" as="xs:integer">
<xsl:param name="n" as="xs:integer" />
<xsl:sequence select="if (($n = 1) or ($n = 2))
then
1
else
(myfunc:fibonacci($n - 1) +
myfunc:fibonacci($n - 2))"
/>
</xsl:function>
</xsl:stylesheet>
The problem is, that it takes long time for large values of n. I
observed the following timing
n=32 -> 35.5 secs
n=33 -> 55.2 secs
n=34 -> 1 min 27.3 secs
n=35 -> 2 mins 20.1 secs
Is it possible I can improve the performance of this stylesheet for
large values of n?
Regards,
Mukul
