string-join

[Al Bondy]

Hi,

I'm trying to use the XSL function string-join() as explained at the
following link : http://www.w3.org/TR/xpath-functions/#func-string-join

Here is my line of code
<xsl:value-of select="string-join(('Now','is','the','time','...'),'
')" />
which returns the following error :
"System.Xml.Xsl.XsltException:
'string-join(('Now','is','the','time','...'),' ')' is an invalid XPath
expression."
I would expect the following string:
"Now is the time ..."

However, this line of code
<xsl:value-of select="concat('Now ','is ','the ','time ','...')" />
returns me the expected string, telling me that my problem is with the
string-join() function
"Now is the time ..."

But, I need to use the string-join() function...

Here is the header of my XSL file:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema" >

Any help will be much appreciated.

"System.Xml.Xsl.XsltException:

That system implements XSLT 1.0 (The current recommendation)

http://www.w3.org/TR/xpath-functions/#func-string-join

That is part of the current _draft_ of Xpath 2.0 so to use it in XSLT
you need an implementation of the current working draft of XSLT 2.0, the
only implementation that's currently advertised as being supported is

Thanks David,
That explains a lot.
What I actually need is a function that returns me 'n' times a string
's', which I'd like to use as follow:
<xsl:value-of select="myFnc(($s,$n)" />

Do you know if this function exists in XSLT 1.0 (couldn't find it), or
how could I write it myself ?

Thanks
Al
