Scripting Wikipedia to get RTL languages list

rtl_from_wikipedia.md

This shows how to obtain a list of the known languages that are written from right to lift.

Scripting is done on ISO 15924 Page on Wikipedia

Get Data Container:

var t = document.querySelector('table.wikitable');
var tb = t.getElementsByTagName('tbody');
var ch = tb[0].children;
ch = ch[0];

Define the lists:

var rtl_iso_code = []
var rtl_iso_num = []
var rtl_unicode = []
var rtl_full = []

Pupulate the lists:

for (var i = 0; i < ch.length; i++) {
  var c = ch[i];
  if (c.children[4].innerHTML == "R-to-L")
    rtl_iso_code.push(c.children[0].innerHTML);
}

for (var i = 0; i < ch.length; i++) {
  var c = ch[i];
  if (c.children[4].innerHTML == "R-to-L")
    rtl_iso_num.push(c.children[1].innerHTML);
}

for (var i = 0; i < ch.length; i++) {
  var c = ch[i];
  if (c.children[4].innerHTML == "R-to-L")
    rtl_unicode.push(c.children[3].innerHTML);
}

for (var i = 0; i < ch.length; i++) {
  var c = ch[i];
  if (c.children[4].innerHTML == "R-to-L")
    rtl_full.push(c.children[2].children[0].innerHTML);
}

The lists extracted:

for(var i = 0; i < rtl_iso_code.length; i++){
  str += rtl_iso_code[i] + " ";
}
console.log(str);

// Output:
// Adlm Arab Aran Armi Avst Cprt Egyd Egyh Hatr Hebr Hung Inds Khar Lydi Mand Mani Mend Merc Mero Narb Nbat Nkoo Orkh Palm Phli Phlp Phlv Phnx Prti Samr Sarb Syrc Syre Syrj Syrn Thaa Wole

str = ""
for(var i = 0; i < rtl_iso_num.length; i++){
  str += rtl_iso_num[i] + " ";
}
console.log(str);
