Empty document if passing HTML comments

[muschellij2]

I've bene using html_nodes in @tidyverse rvest to try to extract elements of extracted HTML, but I realized if I accidentally put in a commented string, it gives back a proper html_document, but then xml_find_all has an issue.

@carriewright11

string = "<!-- <img src=\"https://docs.google.com/\"/> -->"
doc = xml2::read_html(string)
doc
#> {html_document}
class(doc)
#> [1] "xml_document"
rvest::html_nodes(doc, xpath = "//img")
#> Error in UseMethod("xml_find_all"): no applicable method for 'xml_find_all' applied to an object of class "xml_document"
xml2::xml_find_all(doc, xpath = "//img")
#> Error in UseMethod("xml_find_all"): no applicable method for 'xml_find_all' applied to an object of class "xml_document"
