At this point, there is no tool in the Test Studio user interface to set up data driven find expressions. You can, however, use a coded step. You may already know how to add an XML document as a data source. Once you have done so, you can use code to find an HTML link based on the value of a variable in your XML document. The last code sample on the page accomplishes your goal, where "Col1" is the name of the variable in your XML document containing the TextContent you are searching for. Please let us know if we can help you further.
All the best,
