Description
Fell into this today:
xml2::read_html("<!DOCTYPE html>")Rscript -e 'xml2::read_html("<!DOCTYPE html>")' # to ensure it's not RStudio or R GUI causing the issue
{xml_document}
Error in eval(substitute(expr), envir, enclos) :
external pointer is not valid
Calls: <Anonymous> ... xml_attrs -> xml_attrs.xml_node -> node_attrs -> .Call
Execution haltedThat's with the github version of xml2. With the CRAN version of xml2 it hard crashes R.
Of note:
Rscript -e 'XML::htmlParse("<!DOCTYPE html>")'works fine.
I'm trying to put together some small reproducible examples that also break both xml2 and XML but I suspect I'll be filing those bugs with the libxml2 folks.
Rscript -e "library(xml2); library(XML); devtools::session_info()"
