Thank you for evaluating Test Studio. According to your explanation and looking the screenshot, you are trying to verify the test content of a Grid Cell. However you didn't specify what type of Grid or Table you are testing. Is it a Silverlight or an Html? Is it a generic control or a RadControl? Please give us as much info as possible.
Instead of using regex (which are always overly complex) you can use our testing framework capabilities to accomplish your scenario. See this video
for an example with similar verification against this HTML5 DataGrid demo
If you continue to have difficulty, please provide us with a direct access to your application or point us to similar publicly accessible application and we'll be glad to assist you with the desired verification. If you feel that information is sensitive, you can re-open your support ticket 604868 and provide the info there. Support tickets are confidential unlike forum threads.
If you nevertheless want to use a Regular Expressions, there's plenty of info online. Here
is an example. You can use them with Test Studio
using the same syntax.
