item_get_wfs(ex_id) doesn't seem to be working for any ex_id we've tried.

well, good news and bad news. the good news: i found three items that work!

wfs <- item_get_wfs('57681584e4b07657d19f586d')
## OGR data source with driver: ESRI Shapefile 
## Source: "C:\...\Temp\1\RtmpSehK0O/file1e607e963f41", layer:  "USA_MO_Ironton_Airborne_survey_footprint_2016"
## with 1 features
## It has 22 fields
library(maps)
library(sp)
map('state', regions = 'missouri')
plot(wfs, add = TRUE, col='blue')

image

the other working items i found are 5699855be4b0ec051295ed8b and 58cbe556e4b0849ce97dcd31.

the bad news: i found 97 that should have but didn't work.

Warning messages:
1: closing unused connection 3 (https://www.sciencebase.gov/catalogMaps/mapping/ows/571e2412e4b071321fe5653f?service=wfs&request=GetFeature&version=1.3.0) 
2: In xpath_search(x$node, x$doc, xpath = xpath, nsMap = ns, num_results = Inf) :

when an item does work, it has a WFS link on its browser-accessible page, e.g., https://www.sciencebase.gov/catalog/item/57681584e4b07657d19f586d

item_get_wfs can't currently handle >1 layer; based on the above sample, it looks like there are many items where this would be useful.
