var test = document.getElementById('test-list'); li = test.getElementsByTagName('li'); for(var i=0;i<li.length;i++){ // console.log(li[i].innerText); if(li[i].innerText === 'Swift' || li[i].innerText === 'ANSI C' || li[i].innerText === 'DirectX'){ // console.log(li[i]); test.removeChild(li[i]); } }
