Question

I have a text file contains:
<Response>
<IP>17.178.96.59</IP>
<CountryCode>US</CountryCode>
<CountryName>United States</CountryName>
<RegionCode></RegionCode>

US,
United States,
nil,
nil,
Chicago,
nil,
America/Chicago,
37.751,
-97.822,
0
Using the Lua script.

Answer 1

You don't show what you already tried, but there is a recently discussed SO question on how to iterate over XML nodes that should work well for your purposes. Just replace fixed element names with something like [%w_]+ and collect parsed values into a table and you'll get the result you are looking for.

Answer 2

This is what I am trying to do.
int = getInternet()
url3 = 'https://freegeoip.app/xml/17.178.96.59'
result = int.getURL(url3)
result = result:gsub("><",">nil<"):gsub("<.->",""):gsub("%c%s+",","):sub(2)..'nil'
print(result)
-- = 17.178.96.59,US,United States,nil,nil,nil,nil,America/Chicago,37.751,-97.822,0,mil
geoResult = {}
for word in string.gmatch(result, '([^,]+)') do
--print(word)
table.insert(geoResult, word)
--for i,v in ipairs(result) do print(i,v) end
end
print('IP : '..geoResult[1])
print('Country ID : '..geoResult[2])
print('Country Name : '..geoResult[3])
print('Region Code : '..geoResult[4])
print('Region Name : '..geoResult[5])
print('City : '..geoResult[8])
print('ZIP Code : '..geoResult[7])
print('Time Zone : '..geoResult[8])
print('Latitude : '..geoResult[9])
print('Longitude : '..geoResult[10])
print('Metro Code : '..geoResult[11])
-- result:
17.178.96.59,US,United States,nil,nil,nil,nil,America/Chicago,37.751,-97.822,0,nil
