I'm pretty new with regular expression. Basically, I would like to use regular expression to remove `<sup> ... </sup>` from the string using regular expression.

Input:

```
<b>something here</b><sup>1</sup><sup>,3</sup>, another here<sup>1</sup>

```

Output:

```
<b>something here</b>, another here

```

Is that a short way and description on how to do it?
