title: reddit scrapy xpath inconsistencies
body: <p>I want to extract the following information from each reddit post:</p>
  
  <p>post title : (contained in the following xpath as an example) :</p>
  
  <pre><code>&lt;h2 class="s56cc5r-0 kTdpMJ"&gt;Japanese Weekly Tournament "Legacy Weekly Japan#142" is now live!&lt;/h2&gt;
  </code></pre>
  
  <p>link to the post : </p>
  
  <pre><code>&lt;a data-click-id="body" class="SQnoC3ObvgnGjWt90zD9Z" href="/r/starcraft/comments/9q30xf/japanese_weekly_tournament_legacy_weekly_japan142/"&gt;&lt;h2 class="s56cc5r-0 kTdpMJ"&gt;Japanese Weekly Tournament "Legacy Weekly Japan#142" is now live!&lt;/h2&gt;&lt;/a&gt;
  </code></pre>
  
  <p>user who posted : (contained in the following xpath as an example) : </p>
  
  <pre><code>&lt;a class="_2tbHP6ZydRpjI44J3syuqC s1461iz-1 gWXVVu" href="/user/Horiken"&gt;u/Horiken&lt;/a&gt;
  </code></pre>
  
  <p>comment :</p>
  
  <pre><code>&lt;a rel="nofollow" data-click-id="comments" data-test-id="comments-page-link-num-comments" class="_1UoeAeSRhOKSNdY_h3iS1O _1Hw7tY9pMr-T1F4P1C-xNU _2qww3J5KKzsD7e5DO0BvvU" href="/r/starcraft/comments/9q30xf/japanese_weekly_tournament_legacy_weekly_japan142/"&gt;&lt;i class="icon icon-comment _3ch9jJ0painNf41PmU4F9i _3DVrpDrMM9NLT6TlsTUMxC" role="presentation"&gt;&lt;/i&gt;&lt;span class="FHCV02u6Cp2zYL0fhQPsO"&gt;1 comment&lt;/span&gt;&lt;/a&gt;
  </code></pre>
  
  <p>All of these are contained under div elements wth an id attribute, so I start my xpath as follows:</p>
  
  <p>".//div[@id]"</p>
  
  <p>but when i do (for the post url for example) :</p>
  
  <p>".//div[@id]//a[@data-click-id]"</p>
  
  <p>I get an empty result back. </p>
  
  <p>Even when I copy paste the xpath locations I still get empty resuts when I use scrapy response selectors. What is the correct xpath?</p>
