function curl(x,y){let txt; var result; var rx = new RegExp(`["|" ]${y}[ "|" | " |"]:[ "|" | " |"|["](.+?)[}|"]`, 'g');
fetch(x).then(r => r.text()).then(t => {
t.match(rx).forEach(e => { var v = e.replace(rx, '$1');  txt += v + ',' });
var re = decodeURIComponent(JSON.parse('"' + txt.replace(/\"/g, '\\"') + '"'));
result = re.replace(/undefined|"|,\s*$/g,'').replace(/,,/g,'<br>');
alert(result);
});
}
