Extended Replace with Regular Expressions

Question

I am trying to figure out how to user regular expressions in
HomeSite 5.5 extended search and replace.
I am trying to find all matches to: <span
class="someClass">FooText</span>
And replace with: <sometag>FooText</sometag>
I have been able to get the find part working with reg ex:
<span class=\"someClass\">*[A-Za-z0-9_
><.="']*</span>
However, I have not been able to figure out what to put in
the replace box. I have tried different combinations of syntax with
"\1" for the first match of the reg ex in the search field, but
nothing has worked.
Can someone help me out with the syntax for what I should
enter in the replace field?
