Hi
I'm trying to write a check to see if the word "error" is visible anywhere on the current page: how might I do this?
I'd hoped to be able to do something like...
Element e = Find.ByContent("p:error");if (e.Equals(null)){ Log.WriteLine("Could not find error message");}But I get this error:
System.NullReferenceException: Object reference not set to an instance of an object.
Any help gratefully received.
Thanks

Here is a sample piece of code that you may use to search for a word:
IList<Element> e = ActiveBrowser.Find.AllByContent("p:error");if (e.Count == 0){ Log.WriteLine("Could not find 'error' message");}else{ foreach (Element elem in e) { // print the inner text of the element Log.WriteLine(elem.InnerText); }}This will find all elements that contains 'error' string. It will work for all elements that are not in iframe though. If you have frame elements in your application - first you have to find this frame and than search in it.
I hope this clarification helps.

Hi
Thanks very much for that. I've tried it but unfortunately it doesn't find the word "error" as I was expecting.
In the attached screenshot the word "error" appears a few times but when I run the code above on it, it goes down the "Log.WriteLine("Could not find 'error' message");" branch.
I've highlighted the DOM at the bottom to show that at least one of the "error"s is not in its own frame.
Any ideas of other things I could try please?
Thanks
Mike
I reproduce your DOM structure and I still get the searched value using this code.
If your application is a dynamic one - double check that the search step is applied after the element containing "error" message appears in the DOM.

Hi
Thanks very much for your advice. If I run your code on a simple page it finds the text correctly.
The application I'm testing is dynamic, so I'm guessing that it might be a timing problem. I've tried putting a long delay (5 seconds, which is long after the page has finished loading) after loading the page but before I run the search step: unfortunately it still isn't finding the search text.
Is there a way of making sure that the DOM is fully ready before I run the search step?
Thanks
Mike
It could be not a timing problem. If this word appears in a part of your application that is attached to the DOM due to an user action like a button click or entering a text and submit - you have to search for it after that action. You may use "Wait for Exist" step to be sure that you have the element in the DOM that contains the word.

Hi
Thanks for your help: I've got it working now.
What I needed to do was to add a "Wait for exist" for an element that is on every page of the app I'm testing (not necessarily the element that I was searching for). Once I'd added that, your search code worked fine.
Thanks again
Mike
