Rather than using the above (or the above with namespaces) as data
elements in your stylesheet and then doing something like:
<xsl:value-of select="name(document('')/*/my:months/*[$monthNum])" />
you would declare a global variable:
<xsl:variable name="months">
<January />
...
</xsl:variable>
and then do:
<xsl:value-of select="name($months/*[$monthNum])" />
Now that we don't have result tree fragments, defining a tree in a
variable (a temporary tree) and accessing information from that tree
is very easy.
Like Mike, I expect that this will be used in preference to the
document('') method as it's much less fiddly and works well across
multiple stylesheet modules.
Cheers,
Jeni
