Removing Commas

I've written a regular expression in which three
numbers are returned. E.g (1-10) of 750,0000 results
found.

The regex that I've did worked and it's:

 regexp="<font size=-1>Results <b>([0-9]*)</b> -
<b>([0-9]*)&</b> of about <b>([^<]*)</b>"
parenthesis="3" subgroup="3" />

I managed to get 750,000 but I do not want the commas
I need to remove those.

Is there any syntax that I need to add /change to the
current regex?

Thank you.
