There's ready snippet in link above.

If you wanna use php you can do it only in CodeCreator.

Will this code loop itself until it finds the element? What if the page return as server code 5xx error, what happens then?

This one? http://zennolab.com/discussion/threads/progruzka-stranicy-i-ehlementov-na-stranice.10529/#post-62000
It will wait for element. When time is out it will go to next action

Yes that one. But what if the server return an 502 error and it didn't find the element, how can I know. Am I missing something on that thread?

Im using btw:

Код:

HtmlElement he;
for(int i=0;i<20;i++)
{
    he = instance.ActiveTab.FindElementByAttribute("Your data in parameters");
    if(!he.IsVoid)
    {
        break;
    }
    System.Threading.Thread.Sleep(2000);
}

this code doesnt have in-built logic and it will be succesful in 100% of cases. you need to throw error if element is not found?

mtantouri · 18.02.2015

Could you possibly include that in the code if it's that hard for you, please :-)

Thank you.

Edit: I did read and try a couple of things without any luck with https://help.zennolab.com/en/v5/zennoposter/5.1/ZennoLab.CommandCenter~ZennoLab.CommandCenter.Document~FindElementByAttribute.html

    {
        found = true; break;
    }
    System.Threading.Thread.Sleep(2000);
}
if (!found) throw new Exception("not found");
