How do I exclude certain text in an HTML p tag with Nokogiri using CSS selectors? -

i dealing html follows structure below. want ignore "random text" , want pull "text want" css selector.

the selector using right pulling of text:

variable = page.css('div.eight.columns.listingdetail p') 

this html:

<div class="eight columns listingdetail"> <p> <span class="bold">random text</span> text want 1 </p> <p> <span class="bold">random text</span> <span class="bold price"> text want 2 <span></span> </span> </p> <p> <span class="bold">random text</span> </p> <p> <span class="bold">random text</span> text want 3 </p> </div> 

so first p , inside find last element , text:

puts page.css('div.eight.columns.listingdetail p').first.children.last.text 

and find span bold , price classes inside 1 of p element , text:

puts page.css('div.eight.columns.listingdetail p span.bold.price').text 

and last one:

puts doc.css('div.eight.columns.listingdetail p').last.children.last.text
