Hi Folks,
I need to write a stylesheet which dynamically alters the value of a
globally scoped variable.
Some thoughts come to mind:
1. Create a global variable with a value, and then dynamically change
the value. Regrettably this is not allowed in 1.0 or 2.0.
2. Create a range variable with a sequence of values. From reading the
specs this seemed promising. Here's an example of how this might work:
<xsl:template match="/">
<xsl:value-of select="for $i in (1 to 10) return (ex:print())"/>
</xsl:template>
<xsl:function ex:print">
<xsl:value-of select="$i"/>
</xsl:function>
From reading the specs I got the impression that the range variable ($i)
would have a scope over everything within "return (...)". In my
example, within the return is a call to a function. I was thinking that
the range variable's scope would extend to the ex:print function. Alas,
it doesn't (unless there is a bug in SAXON).
I am out of ideas. Is there any way to create a dynamically changeable
global variable? /Roger
