RE: [xsl] Passing a variable number of parameters or rather an array

["Matthieu Ricaud" <matthieu.ricaud@xxxxxxx>]

using XSLT 1.0, you can simulate the tokenize XSLT 2.0 function with an
simple reccursive named template, in your case something like this :

	<xsl:template name="MakeTreeFromStrList">
		<xsl:param name="strList"/>
		<xsl:choose>
			<xsl:when test="contains($strList,',')">
				<foo><xsl:value-of select="substring-before($strList,',')}"/></foo>
				<xsl:call-template name="MakeTreeFromStrList">
					<xsl:with-param name="strList" select="substring-after($strList,',')"/>
				</xsl:call-template>
			</xsl:when>
			<xsl:otherwise>
				<foo><xsl:value-of select="$strList"/></foo>
			</xsl:otherwise>
		</xsl:choose>
	</xsl:template>

calling the template inside a variable declaration with $sampleString as
param will make your variable a node-set, which you can interate :

	<xsl:variable name="tokenizedSample">
		<xsl:call-template name="MakeTreeFromStrList">
			<xsl:with-param name="strList" select="$sampleString"/>
		</xsl:call-template>
	</xsl:variable>

with <xsl:variable
name="sampleString">XML,XSLT,XPath,SVG,XPointer</xsl:variable>
$tokenizedSample is the folowing xml fragment :
	<foo>XML</foo>
	<foo>XSLT</foo>
	<foo>XPath</foo>
	<foo>SVG</foo>
	<foo>XPointer</foo>

which you can iterate using a node-set extension (depends on your parser)
with MSXML it looks like this :
    <xsl:for-each select="msxsl:node-set($tokenizedSample)/foo">
      <xsl:value-of select="."/>
      <xsl:text>! </xsl:text>
    </xsl:for-each>

this is untested..., and hoppefully it is not out of subjetc (i didn't read
the whole thread...)
hope this help anyway,
regards
Matthieu.

Thanks everyone for the help.

Argh, so I tried this approach and I even found another example of it at:
http://www.xml.com/lpt/a/2003/05/07/tr.html

And yet it doesn't work in xalan, which is frustrating:

<xsl:variable name="sampleString">XML,XSLT,XPath,SVG,XPointer</xsl:variable>

<xsl:variable name="tokenizedSample" select="tokenize($sampleString,',')"/>

    <xsl:for-each select="$tokenizedSample">
      <xsl:value-of select="."/>
      <xsl:text>! </xsl:text>
    </xsl:for-each>

does anyone know why this gives me the error:

ERROR:  'Error checking type of the expression 'funcall(tokenize,
[variable-ref(sampleString/result-tree), literal-expr(,)])'.'
FATAL ERROR:  'Could not compile stylesheet'

Just give this a try..... I havent tried it out myself....

Step1 :  Store it into a variable..
Step 2:  Iterate through using <for-each>

<for-each select="tokenize($category,'\s+')">
  <individualFruit>
    <xsl:value-of select="."/>
  </individualFruit>
</xsl:for-each>
