[XML4Lib] XSLT call name of variable dynamically?

[Walker, David]

Thanks for all the responses, everyone!  My second approach is working well now -- sometimes sending a message to a listserv allows you to focus more clearly on what you've already done -- so I'm good.  But you've given me some other ideas for future stuff, so it was well worth the discussion.

Hi David -

Just re-read this message & realized that my previous message didn’t
cover your exact use case.

If you really want to do it like this, look at exslt:eval(...) [1].

Another way would be the basic method I outlined in the last message,
but with per-stylesheet variables:

<xsl:variable name="labels">
  <labels>
    <label name="text_breadcrumb_databases_categories" value="..."/>
  </labels>
</xsl:variable>

then use select="exslt:node-set($labels)//label[@name=$var]/@value"
(or something like that).

I’m still not sure why you need per-page overrides for label text, but
it could be done like this.

best,
Erik Hetzner
