I would need to see a specific example. Can you post screenshots of your control and it's InnerHtml and then your automation?

I am no HTML expert, but "Style" doesn't look like an attribute. It doesn't follow the pattern attribute=value. Perhaps that is the problem. If you just need the stuff after the word style, you might use a RegEx on the InnerHTML of the control.

I would use a RegEx on the InnerHtml. Here;s a script you can paste into the script container. Just be sure to add a using statement at the top for System.Text.RegularExpressions;

        public string getStyle(string innerHtml)
        {
            /// <summary>
            ///  Regular expression built for C# on: Wed, Dec 11, 2019, 06:09:09 AM
            ///  Using Expresso Version: 3.0.5854, http://www.ultrapico.com
            ///  
            ///  A description of the regular expression:
            ///  
            ///  Style".+"
            ///      Style"
            ///      Any character, one or more repetitions
            ///      "
            ///  
            ///
            /// </summary>

            Regex regex = new Regex(
              "Style\".+\"",
            RegexOptions.CultureInvariant
            | RegexOptions.Compiled
            );

            //// Capture the first Match, if any, in the InputText
            Match m = regex.Match(innerHtml);
            return m.ToString();
        }

I don't really understand what you mean. Can you put together an example solution and attach it to the post?
