A Find expression to find everything in span tag

I imported word doc into my robohelp project and there is a lot of span tag junk i want to get rid of.

Is there an expression i can build in the "find and replace" tool that will find any span tag and its contents?

In the following example I want to delete the whole string including the brackets:

<span style="letter-spacing: .05pt;">

I'm thinking possibly a wildcard like: <span ***>

I don't see a wildcard option in robohelp help related to building find expressions.
