There may be a better way, but using revXMLChildNames allows you get the child names with the index appended (e.g. name[1], name[2], etc.)

 put field 1 into tData //source of xml text
 put revXMLCreateTree(tData,true,true,false) into tID
 put revXMLChildNames(tID, "person/aliases/", cr, "name" ,true) into tNameNodes
 put "" into tOut
 repeat for each line tNodeName in tNameNodes
   put "person/aliases/" & tNodeName into tNode
   put revXMLNodeContents(tID, tNode)  & cr after tOut
 end repeat
 put tOut into field 2
