Here's a follow-up: I've also added a function named jsonget. It's in the snapshots for Windows and OS X quartz. To get use it on Linux you have to build from CVS, with the json-glib-1.0 library installed (plus its "dev" or "devel" package, if that's separate). This function takes two string arguments: the first should be a JSON buffer (as acquired via the curl function), and the second is the JsonPath to what you want. The function returns a string (with one element per line if the thing you want is an array). For the syntax of JSON paths, see https://developer.gnome.org/json-glib/stable/JsonPath.html or http://goessner.net/articles/JsonPath/ Here's a complete working example: <hansl> set echo off set messages off bundle req req.URL = "http://api.bls.gov/publicAPI/v1/timeseries/data/"; req.header = "Content-Type: application/json" string s sprintf s "{\"seriesid\":[\"APU0000701111\"],\"startyear\":\"2002\",\"endyear\":\"2012\"}" req.postdata = s curl(&req) s = req.output check = jsonget(s, "$.status") if check != "REQUEST_SUCCEEDED" print "Failed to get data" quit endif string allval = jsonget(s, "$.Results.series[0].data[*].value") string allyrs = jsonget(s, "$.Results.series[0].data[*].year") string allper = jsonget(s, "$.Results.series[0].data[*].period") string val yr per printf "obs %s\n", jsonget(s, "$.Results..seriesID") loop while getline(allyrs, yr) --quiet getline(allper, per) getline(allval, val) printf "%s:%s %s\n", yr, per+1, val endloop </hansl> Allin
