When I execute below command I'm getting more than 3000 items to my elm variable. Then I have to pass them in to a string array.

The below list contain so many blank data and there are some items which contains characters. But I need only elements with numbers. So is there any problematical way to remove all the blank elements and the elements with characters.

     IList<IWebElement> elm = driver.FindElements(By.ClassName("spy14"));

I was trying with a for each loop, but I stucked on some place.


    elm = elm.Where(x => !x.Text.Contains(" ")).ToArray();

With @PDHide's help I was able to get this thing done with above code.

  • Voting for closing because this question is regarding programming. On Stack Overflow people can tell you about list filters. Aug 31, 2020 at 6:38
  • I was thinking IList<IWebElement> are mostly used by test engineers ,and that's why I post it here.

You won't get blank data as its a IWebElement type list. If you meant that when you try to get text it returns empty for few elements then use:

 elm = elm.Where(x => !string.IsNullOrEmpty(x.Text)).ToList();

You will get elements for which Text is not Null or empty:

Reference: https://docs.microsoft.com/en-us/dotnet/api/system.linq.enumerable.where?view=netcore-3.1#System_Linq_Enumerable_Where__1_System_Collections_Generic_IEnumerable___0__System_Func___0_System_Boolean__

For getting only numbers try

 elm = elm.Where(x => decimal.TryParse(x.Text, out decimal myInt)).ToList();
  • Yeah its the text.
