element(by.xpath("//div[@id='patients']")).all(by.xpath("div[@class='ng-scope']")).then(function(divtags){for(i=0;i<divtags.length;i++){divtags[i].element(by.xpath("div[1]/div[2]")).getText().then(function(time){if(time==createdTime){ /*Here i am getting 'i' value every time last divtag length */        divtags[i].element(by.xpath("div[@class='patient']")).getText().then(function(patientName){if(patientName==createdPatient){divtags[i].click();}})}});}});
