Could someone provide a link or examples of parsing XML document in R? Few specific questions below:

For instance I can retrieve specific nodes using this: node <- xpathApply(xml, "//" %+% xtag, xmlValue)

  1. I want to be able to retrieve parent node for this node, how can I do this? getParentNode() does not seem to cut it.
  2. How can I retrieve children nodes for a particular node?
  3. How can I create an iterator to iterate through the whole tree?

Thank you,
Pratt
