This uses the xml-viewer JavaScript module to provide a simple collapsible tree viewer for HTML/XML documents, nodes, node sets and plain character HTML/XML in an htmlwidget pane.

xml_tree_view(doc = NULL, mode = c("traditional", "modern"),
  scroll = FALSE, width = "100%", height = NULL)

html_tree_view(doc = NULL, mode = c("traditional", "modern"),
  scroll = FALSE, width = "100%", height = NULL)

`doc`	`xml2` document/node/nodeset, an `HTMLInternalDocument`/ `XMLInternalDocument` or atomic character vector of HTML/XML content
`mode`	viewer mode. `traditional` uses tag notation; `modern` favors readability oveer angle brackets.
`scroll`	should the `<div>` holding the HTML/XML content scroll (`TRUE`) or take up the full viewer/browser window (`FALSE`). Default is `FALSE` (take up the full viewer/browser window). If this is set to `TRUE`, `height` should be set to a value other than `NULL`.
`width`	widget `div` width
`height`	widget `div` height

Large HTML or XML content may take some time to render properly. It is suggested that this function be used on as minimal of a subset of HTML/XML as possible or used in a browser context vs an IDE viewer context.
