问题 I'm building a workflow for reading multiple-geometry KML files into R. This is my working map, with point and path geometries.

阅读更多关于 Parsing small web page with xml2 throws XML_PARSE_HUGE error

Recently a user of my rNOMADS package in R began getting unexpected errors: Error: Excessive depth in document: 256 use XML_PARSE_HUGE option [1] We tracked the issue down to this command: html.tmp <- xml2::read_html("http://nomads.ncep.noaa.gov/cgi-bin/filter_rap.pl?dir=%2Frap.20151120") Upon following the link, it appears that the web page to be parsed is no larger than other ones that work fine, and much less than the 1 megabyte limit that should require the XML_PARSE_HUGE option. Furthermore, xml2::read_html actually has no XML_PARSE_HUGE option anyway. The only other potential solution,
