Newbie help; getting the text outside of span tag

Newbie help; getting the text outside of span tag

<span class="uc-price-product uc-price-sell uc-price"><span class="price-prefixes">Price: </span>$34.00</span>

My generated HTML is like above.  How do I get 34 from above? 

I tried the following to get $34.00 like this, but not working:
alert ($(".uc-price-list").text());  //it is getting inner span along with the $34.00; i just want number part.  Thanks for the help.
