RE: How to do a dynamic XML lookup within a repeat?

Thanks Mark - figured it was something easy! And yeah, now that I think of
it, I did have to use current() in some XSLT as well. I'll give it a try. 

Regards,

Brian.

The answer to your question doesn't lie within XForms or FormsPlayer!
You
need to use "current()" in place of ".", since as you rightly say, the
context for the @name comparison has changed to be the 'element'.

This works:

xforms:instance('metaData')/element[@name=local-name(current())]/@label

As it happens, this is a problem that people often have when doing XSLT,
and
it also catches people out with xf:bind.
