Okay,
Now I have a different approach. I define a function:
<xsl:function name="s:measure-block">
<xsl:param name="length-left"/>
<xsl:if test="$length-left > 0">
<xsl:text>e</xsl:text>
<xsl:value-of select="s:measure-block($extent-left - $extent)"/>
</xsl:if>
</xsl:function>
and I'm calling it with
<xsl:value-of select="string-join(s:measure-block($length),'')"/>
... i.e., an old fashioned recursive function.
Any notions as to what the relative virtues are of this vs the XPath 'for x
return y' approach, if the casting problem below can be solved?
Thanks,
Wendell

Hi,
I'm trying to write an expression in XPath 2.0 to return me a string given
a numeric argument as input, plus a parameter.
Call the parameter 'extent'. If $extent is 42, I'd like
(42) => e
(43) => ee
(84) => ee
(85) => eee
that is, as many 'e' as ceiling($arg div $extent)
But if I say
string-join((for $i in (1 to ceiling($arg div $extent)) return 'e'),'')
I get an error (Saxon 8.4) telling me I need an xs:integer as the second
argument of the range expression "1 to ceiling($arg div $extent)", but I
have an xs:decimal.
How do I make ceiling($arg div $extent) into an integer?
Alternatively, what neater ways are there to generate the string I need?
Am I even approaching this the right way?
Cheers,
Wendell
