Div.prototype.nele=function(component,data)
{

var children =component.findElement(By.xpath(".//*));

if(children.length!=0){
for(var ele in eles)
{
if(ele!=null){
if(ele.getText()==data.get("text")){

You might be missing on the syntax:

var children =component.findElement(By.xpath(".//*"));

Also do have a look at this thread for element not found exception https://www.edureka.co/community/399/selenium-xpath-error-element-not-found
