RE: [xsl] xsl:function

["Dominic Blythe" <dblythe@xxxxxxxxxxxxxxxxxx>]

thanks David...
having noted that saxon7 is alpha only, i've gone back to 6.5.2
so the following has <saxon> elements. I'm trying to pad the string
out to a given length to output in fixedwidth format. The <xsl:variable/>
on line 5 doesnt seem to work - when i return $paddedString without
doing the <saxon:while/> it is empty. I expect it to be the equal to
$theString as set in the expr attribute.

<saxon:function name="pcs:pad">
	<xsl:param name="theString"/>
	<xsl:param name="fixedLength"/>
	<xsl:variable name="i" expr="string-length($theString)"
saxon:assignable="yes"/>
	<xsl:variable name="paddedString" expr="$theString"
saxon:assignable="yes"/>
	<saxon:while test="$i &lt; $fixedLength">
    		<saxon:assign name="i" expr="$i+1"/>
		<saxon:assign name="paddedString" expr="concat($theString,' ')"/>
	</saxon:while>
  	<saxon:return select="$paddedString"/>
</saxon:function>
