title: GetElementsBy ... (javascript)
body: <p>I want to get the href value of the link that has rel='edit', i am wondering how i can do it.</p>
  
  <pre><code>&lt;link rel='self' type='application/atom+xml' href='https://spreadsheets.google.com/feeds/****'/&gt;
  &lt;link rel='edit' type='application/atom+xml' href='https://spreadsheets.google.com/feeds/****'/&gt;
  </code></pre>
  
  <p>I am trying</p>
  
  <pre><code>this.url = entry.getElementsByTagName('link')[1].getAttribute('href');
  </code></pre>
  
  <p>but i get href of the first link.</p>
  
  <p>thanks.</p>
  
  <p><strong>EDIT :</strong></p>
  
  <p>now what i don't understand is thateven when i am sure i get the right link, the href value is not what i expect</p>
  
  <pre><code>&lt;link rel='self' type='application/atom+xml' href='https://spreadsheets.google.com/feeds/list/**********/full/ba0fz'/&gt;
  &lt;link rel='edit' type='application/atom+xml' href='https://spreadsheets.google.com/feeds/list/**********/full/ba0fz/27mpei328jki4e'/&gt;
  </code></pre>
  
  <p>what i want is to do a regex on the href i want to get the "27mpei328jki4e"
  but instead of getting the full url, i get the short one, do you have any idea of why i get this result? no matter what method i use, neither the queryselector nor getElementsByTagName.</p>
  
  <p>my document is an xml</p>
