I need to grab a price from one element and add it to another.

I am using this:

$d+(?:.d+)?

Which seems to work for $0.50, $1.00, $20.00, $200.00 but I hit a brick wall on $1,000.00 and $10,000.00

(Unlikely $10,000.00 will ever be used).

The comma is tripping me up.

** Edit **

I went away for an hour to come back to heaps of answers. Before I go through them I thought I'd clarify rather than answering all comments:

The platform being used auto generates the total value of items in a shopping cart. It gets rendered in a an element - this changes depending on whether a user is adding or removing items.

The value is unlikely to go into 10,000.00 because the product costs are not that high.

I am new to using the regex it took me long enough to get this far, hence the question.

Auto generated HTML:

<span vertical=False quote=False id=catCartSummary>

   <table cellspacing=0 class=cartSummaryTable>

     <tbody>

       <tr>

         <td class=cartSummaryItem>3 item(s), Total: $115.00 <a href=# class=cartSummaryLink>View Cart</a></td>

       </tr>

     </tbody>

   </table>

</span>

I just need the $ value in this case $115.00 - But I need it to work for $1,000.00
