Hi,

I am trying to use \xmlfirst to find a reference that is not in the current
node. In the manual there is the exmple:
{\xmlfirst
  {example-3-1}
  {div[@class='footnotes']/ol/li[@id='\xmlrefatt{#1}{href}']}}

This is quite close to what I need, but I am not processing a buffer. How
can I use this lookup mechanism to look over the current file/all nodes?

Best,
Denis
