How to click on a hyperlink in a textbox?

I have a scenario where I have to click on a Hyperlink. 

The Hyperlink is stored in a textbox.

When scripting the scenario, I can click on the Textbox, but only when the Hyperlink is large enough the script continues.

But the hyperlink is most of the time a short text.

So my question is, how can I capture this, that when  clicking on the hyperlink a new window opens.
