not sure I understand what you are trying to do. getData() is for getting the 
contents of a data node. Your <article> node is not a data node. You can do 
getData("article[1]") but it will be empty. If you want a list of the 
children of the <article> node, do an evaluate/match on /article[1]/* or 
whatever; this will return a nodeset array which you can then process with a 
do-loop or whatever on the individual child nodes, for example, to get their 
data contents.
