To traverse the children of a node, you can use the following type of loop:
##
put revXmlFirstChild(tDocId, tParentNode) into tChildNode
repeat until tChildNode is empty
  -- do your thing with the child node
  put revXmlAttribute(tDocId, tChildNode, "icon") into tIconPath
  -- move on to the next child
  put revXmlNextSibling(tDocId, tChildNode) into tChildNode
end repeat
##
