there is no linear processing, you just start someplace and recursively 
deal with the tree (which often looks like linear when you start at the 
root but basically you can access everything everywhere)

just pass the root element i.e. instead of #1 in

  \xmlfilter{#1}{/abstract/command(xml:article-meta:abstract)}

as #1 is just an abstraction for the current element; you pass the name 
you used when loading the tree (often \xmldocument works too)

there are plenty examples in the documentation and test suite and in 
some styles
