Perhaps you can use a regular expression.
If you are using the selector use the .re method:
>>> sel.xpath('//*[@class="priceright
secondarytextbold"]/text()').re("\d+\.\d+")
[u'117.95']
If you are using an item loader use the re argument:
loader.add_xpath('price', '//*[@class="priceright
secondarytextbold"]/text()', re='\d+\.\d+')
