title: Extract text from div class with scrapy
body: <p>I am using python along with scrapy. I want to extract the text from the div tag which is inside a div class. For example:</p>
  
  <pre><code> &lt;div class="ld-header"&gt;
      &lt;h1&gt;2013 Gulfstream G650ER  for Sale&lt;/h1&gt;
      &lt;div id="header-price"&gt;Price - $46,500,000&lt;/div&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>I've extracted text from h1 tag</p>
  
  <pre><code>result.xpath('//div[@class="ld-header"]/h1/text()').extract()
  </code></pre>
  
  <p>but I can't extract Price. I've tried </p>
  
  <pre><code>'price': result.xpath('//div[@class="ld-header"]/div[@id="header-price"]/text()').extract()
  </code></pre>
