Thank you for sharing your ideas.
Though it is important to note that Test Studio is not supporting CSS selector so these could not be applied like you could in Selenium.
On the other hand Test Studio is using an intelligent element identification scheme
which could be even more powerful than css selectors. Even if the elements have dynamic ids they probably could be identified by some of their other attributes and properties or a set of these which point to a unique element on page. Probably you could rely on text content, for example.
The chained find expression could be applicable and useful depending on the structure of the web page under test. In most cases there is a parent element which could be identified by a unique attribute among the rest elements and then could be used to narrow down the amount among which the required one should be identified.
If the above information does not provide sufficient information to accomplish your goals you could probably provide a sample application along with a scenario in which you are facing difficulties. This will be the easiest way to provide exact directions.
Thank you in advance for the cooperation! I am looking forward to hearing from you in case of any further queries.
