title: How to get the latest release version in Github only use python-requests?
body: <p>Recently,I make an app and upload it to my GitHub release page.I want to make a function to check update to get the latest version(in the release pages).</p>
  
  <p>I try to use <code>requests</code> module to crawl my release page to get the latest version.Here it a minimal example of my code:</p>
  
  <pre><code>import requests
  from lxml import etree
  
  response = requests.get("https://github.com/v2ray/v2ray-core/releases")
  html = etree.HTML(response.text)
  Version = html.xpath("/html/body/div[4]/div/main/div[3]/div/div[2]/div[1]/div/div[2]/div[1]/div/div/a")
  print(Version)
  </code></pre>
  
  <p>I think the xpath is right,because I use <code>chrome -&gt; copy -&gt; copy xpath</code>.But it return me a <code>[]</code>.it can't find the latest version.</p>
