[thelist] Generating html links with XSLT

[Dave Merrill]

Hi Volkan, thanks for jumping in. I know about zvon; I'm using Cooktop for
some of my experiments, and it has link there in its Help menu.

I also understand your js-based ideas to avoid having to output @name inside
presetRecall's params, but I'd rather get this working if I can. It seems
cleaner to me, more like what I'd do in straight html or a server-side
language I know better than xslt. I'm also sure this kind of thing will come
up in other contexts, so I'd just like to understand how to do it.

In any case, not from anything I saw on zvon, I've started looking in this
direction:
-----------------------
<a href="#">
	<xsl:attribute name="onclick">
    		<xsl:value-of select="concat('presetRecall(', @name, ')')"/>
  	</xsl:attribute>
  	<xsl:text>Recall</xsl:text>
</a>
-----------------------

That's getting close; the result is:
-----------------------
<a href="#" onclick="presetRecall(foo)">Recall</a>
-----------------------

...where 'foo' (w/o the quotes) is the actual literal value of that node's
'name' attribute. Only thing missing is the quotes I need around the value,
which I still haven't seen a way to do.

I tried this for the select:
-----------------------
select="concat('presetRecall(&#39;', @name, '&#39;)')"
-----------------------
... but got:
ERROR: Description: Expected token ')' found 'STRING'.

I also tried using fn:codepoints-to-string(34), but 'fn' is an unrecognized
namespace, and the function can't be found without it. It looks like that's
not implemented yet in either Cooktop or the libraries underlying ColdFusion
(server-side language used for this).

Any ideas from here? (And thanks again...)
