title: How to get the value of input with Selenium IDE
body: <p>How to retrieve the field value "value" from input via the Selenium IDE (this value is variable so I want to recover its value for reuse)
  My input field:</p>
  
  <pre><code>    &lt;input class="myClass" type="text" value="15" name="myName"&gt;
  </code></pre>
  
  <p>When I tried the following code:</p>
  
  <pre><code>&lt;tr&gt;
      &lt;td&gt;store&lt;/td&gt;
      &lt;td&gt;xpath("//input[@name='myName']").getAttribute(​"value");&lt;/td&gt;
      &lt;td&gt;x&lt;/td&gt;
  &lt;/tr&gt;
  &lt;tr&gt;
      &lt;td&gt;echo&lt;/td&gt;
      &lt;td&gt;${x}&lt;/td&gt;
      &lt;td&gt;&lt;/td&gt;
  &lt;/tr&gt;
  </code></pre>
  
  <p>I have:</p>
  
  <pre><code>[info] echo: xpath("//input[@name='myName']").getAttribute("value");
  </code></pre>
  
  <p>instead of:</p>
  
  <pre><code>15
  </code></pre>
  
  <p>thanks for help</p>
