[colug-432] Command-line Snow Emergency Level

[Rob Funk]

In case you need a command to quickly get the current Franklin County
snow emergency level:


#!/bin/sh
# Franklin County Snow Emergency Level
#
# Required commands:
#     curl
#     xpath (from libxml-xpath-perl package)
#     html2, 2xml (both from xml2 package)

tmpfile="/tmp/snow-$$.xhtml"
url=https://sheriff.franklincountyohio.gov/info/snow-emergency-levels.cfm

xhtml_cleanup() {
    html2 | 2xml
}

##

curl -s "$url" | xhtml_cleanup > "$tmpfile"
status=$?
if [ $status -gt 0 ]; then
    rm -f "$tmpfile"
    exit $status
fi

xpath -q -e "//div[@class='main']/div//text()" "$tmpfile"

rm "$tmpfile"

Those two package names are on Ubuntu. YMMV.

Sending you a message when this changes, or handling other counties,
are left as an exercise for the reader.
