Following an example in the chapter on Expressions and filters for xml-processing one can select on an attribute ‘name’ in the node <file name=“whatever”/> file[@name=="whatever”]/command(todo) However, I would like to select on a combination of alternatives, so that equivalent are <file name=“whatever”/> and <file src=“whatever”/> I tried several variations but none of them work. \xmlfilter{#1}{file([@name=="whatever”] or [@src=="whatever”])/command(todo) \xmlfilter{#1}{file[@name=="whatever”] or [@src=="whatever”]/command(todo) \xmlfilter{#1}{file[@name=="whatever”] or file[@src=="whatever”]/command(todo) \xmlfilter{#1}{(file[@name=="whatever”]|file[@src=="whatever”])/command(todo) How to? Or is this impossible? Hans van der Meer
