  No API lack. You use an API to dump the content of a LIST of node
when you want the content of a SINGLE node.
  There is a zillion ways to get it like accessing directly the
node->content pointer  or using the API getting the content of 
a single node like xmlNodeGetContent()

  Hum, no I just tried to get you to understadn that the data model is
a tree and you need to walk that tree ... and xmllint --debug is a
convenient way to see this tree.
