How to get the img src using Nokogiri and at_css
nokogiri, ruby, ruby-on-rails, ruby-on-rails-4
Solution
If you need the `src` attribute, you can do it like this:
pace.doc.at_css('#idLinkProductMainImage img').attr('src')
Also, I believe the problem is the way you are getting the `img` tag. You are trying to get all `img` tags inside `#productMainImage`, but this `id` is the image itself, so it will find nothing.
If you use the link id `#idLinkProductMainImage`, then you have a `img` tag to search inside it.
Problem
I'm trying to get the `src` value of a block of HTML. I am specifically trying to achieve this using the `at_css` and not using XPath. So far all I'm getting is either nil or a blank string. This is the HTML: ``` <div class="" id="imageProductContainer"> <a id="idLinkProductMainImage" href='URL'> <img id="productMainImage" src="SRC.jpg" alt="alt" title="A Title" align="left" class="product_image_productpage_main selectorgadget_selected"> </a> </div> ``` The code I have is: ``` item = page.doc.at_css("#productMainImage img").text.strip unless page.doc.at_css("#productMainImage img").nil? puts item #prints blank item = item["src"] puts item #prints blank ``` Where `page.doc` is the Nokogiri HTML element.
