Can't apply xml_structure to xml_document

[hadley]

xml_structure(xml_new_document())
#>  no applicable method for 'tree_structure' applied to an object of class "xml_document"

And I think this is the same underlying problem:

root <- xml_new_document()

root %>% 
  xml_add_child("a") %>% 
  xml_add_child("b") %>% 
  xml_add_child("c") 
root
#> {xml_document}

Hmmmm, maybe we should resolve this by making xml_new_document() optionally take a string that gives the name of the root node. Oh, but then you'd also need to take attributes.
